If anything faces an uphill battle to stand out, it’s the AOC CU34G2X from the G2 series. The battle to be the best ultrawide monitor is an ironically crowded market, so how do you make your mark when black and red gaming displays are practically the norm? By showing, not telling.  

Rather than advertising its gamer-centric nature via sharp angles and aggressive RGB lighting, this ‘frameless’ monitor works hard to provide a best-in-class performance, instead.

Although it may not look like much from the outside, this display packs a punch.

  • AOC CU34G2X (Blue) at Newegg for $525

Price and availability

You’ll have no trouble at all if you’re hunting down the AOC CU34G2X in the US or UK; it’s widely available in both territories. What’s more, it’s not offensively priced in either of them. Getting it stateside will set you back around $450, while the UK version is similarly priced at £450.

Unfortunately, the monitor doesn’t seem to be available in Australia – at least not as it appears everywhere else. The closest equivalent appears to be the C32G2E. 

The latter is smaller at 31.5 inches, but it still offers a curved QHD screen, a 1ms response time, and 144Hz (unfortunately, we couldn’t find pricing information for that one at the time of writing).

In a world of over-the-top screens that practically shriek “witness me”, the AOC CU34G2X is refreshingly subtle. It opts for a more subdued approach thanks to sleek black with red accents along a chassis that looks like it could take more than a few knocks. 

Because the base is constructed from sturdy metal, it’s also not going anywhere fast – you don’t have to worry about it toppling over if your desk is knocked.

However, the CU34G2X’s modesty won’t be to everyone’s taste. Although it’s a handsome bit of tech, you could also argue that it’s dull. This is a workmanlike piece of kit without much flair, for better or worse. 

It’s also very similar to the ASUS ROG range, further lessening its impact – every monitor we test these days seems to be constructed from angular black plastic with red trimming, so this one arguably disappears into the crowd as a result.

(Image credit: Future)

However, the AOC CU34G2X has plenty going for it under the hood. To begin with, it’s an ultrawide 34-inch QHD screen with 21:9 widescreen resolution (3440×1440), 144Hz, and a 1ms response time to go with it.

It offers AMD FreeSync as well, not to mention half-a-dozen SS USB ports and the usual display accoutrements. In other words, it’s stacked with all the features you need for modern gaming.


Happily, the AOC CU34G2X’s performance is also much better than any of our earlier quibbles above would suggest. The curve doesn’t feel too overwhelming when leaning in close over your keyboard, and it’s one of the most immersive experiences you can have when you slap on a gaming headset as well. 

What’s more, it’s devastatingly responsive thanks to that 144Hz refresh and 1ms response time – there’s no perceptible screen-tearing even during the intense, busy firefights of The Division 2, for example. 

It also needed no adjustments for great color-balance; the hues and shades of Ubisoft’s shooter and Total War: Warhammer 2 were gorgeous right off the bat.  

(Image credit: Future)

As for range, the CU34G2X is no slouch either. Metro Exodus is always a good show of shadow or light, and AOC’s latest does a superb job. 

Although it verges on the darker end of the spectrum (our gamma tests almost entirely removed the left-most icon you’re barely supposed to see), this is to the game’s benefit.

Skulking around the Moscow underground reveals gloomy tunnels that fall away into a pitch blackness that’s claustrophobic, disorienting, and almost absolute without your torch. 

The screen’s HDR features are pretty good as well despite the CU34G2X not being an actual HDR monitor. They still result in rich, vivid, and deep shades, even though you shouldn’t expect anything mind-blowing (it should also be noted that we went with the standard DisplayHDR mode – the game-specific one was a bit grainier than we liked). 

The one downside? Getting to those settings is a bit of a faff. That’s because you need to press the menu button to bring it up, press again to activate the setting you want, make any changes with the left or right buttons, and then press again to lock your choice into place.  

The buttons themselves also feel small and somewhat tacky. But hey: when the performance elsewhere is this good, we can forgive that. And does it matter all that much? Not particularly.

Final verdict

Despite a subtle but potentially plain design, the AOC CU34G2X is the Millennium Falcon of monitors – it has it where it counts. Superb performance and impressive technical stats make it a worthy purchase, particularly at that sub-$500/£500 price. 

This is also a screen that’ll serve you well going forward. A 144Hz refresh rate and 1ms response time ensure that the demanding games on our horizon – like Cyberpunk 2077 – will look their best.

And even though it’s not a 4K device, that’s not a huge issue right now; 4K gaming is an expensive business requiring nothing but the best hardware, so the CU34G2X is a fine choice for now and the next few years.

Samsung Odyssey Neo G9 review

The behemoth of gaming monitors

Best in Class

(Image: © Future)

TechRadar Verdict

The Samsung Odyssey Neo G9 is an absolute monster of a gaming monitor and packs some of the most impressive tech we’ve ever seen in a PC display. However, the super high price and massive size will probably stop most people from ever getting their hands on it.

There are few gaming monitors out there more luxurious than the Samsung Odyssey G9. The massive 49-inch monitor rocked a massive 5,120 x 1,440 resolution with a 240Hz refresh rate and even backed it up with an HDR 1000 rating. However, 2021 is a whole new year and now we’re getting the Samsung Odyssey Neo G9, which takes everything that the Odyssey G9 did and turns it up to 11. 

We’re talking about better lighting, an HDR 2000 rating and a move to Mini-LED technology, which makes the Samsung Odyssey Neo G9 one of the most advanced gaming monitors we’ve ever seen. However, not only will you need one of the best gaming PCs – probably something like the RTX 3080 as a minimum – the Neo G9 is even more expensive than it was last year.

But it’s largely worth the added cost if you can afford it. The display is genuinely the best we’ve ever used, with amazing color and black levels that you simply won’t find in most other gaming monitors. Playing games on this thing is truly a luxurious experience, which makes the mind-blowing price tag feel at least a little justified.

Pricing and availability

  • Samsung Odyssey Neo G9 at Amazon for $1,308.63

The Samsung Odyssey Neo G9 is available now for a blistering $2,499 (£1,749, AU$2,999). 

This is, by far, one of the most expensive gaming monitors on the market, but it does bring a lot to the table that other gaming monitors simply can’t match. To our knowledge, this is the only gaming monitor with an HDR 2000 rating, which means it knocks the socks off of even the Asus ROG Swift PG27UQ, and it provides the best HDR we’ve ever experienced, including TVs we’ve seen. 

So while the price has been bumped up by a lot over last year’s $1,479 (£1,289, AU$2,799) model, it actually makes sense when you consider all the flashy new tech that Samsung has thrown in here. The Odyssey G9 was already the king of ultrawide gaming monitors, but the Samsung Odyssey Neo G9 takes it to a frankly absurd level that is perfect for the type of gamer that demands nothing but the best experience money can buy.  

It’s definitely a case of “if you get sticker shock looking at the price tag, it’s probably not for you”. It’s something we probably would never fork over money for, but we definitely have had fun in our time with it, and are not looking forward to sending it back to Samsung.

For something a bit less grandiose, consider the Odyssey G7

(Image credit: Future)

The Samsung Odyssey Neo G9 is big. And while that is pretty obvious from the fact that it’s a 49-inch ultrawide monitor, it doesn’t hit until you take it out of its box to set up on your desk. 

We’re lucky enough to have a pretty large 61-inch desk, and even with that it takes up nearly the entire length of it, leaving just enough room for our PC on the side. But, that gargantuan size definitely works in its favor when you’re just looking for an immersive gaming experience. 

When we’re sitting in front of the Samsung Odyssey Neo G9 and playing games – mostly Final Fantasy XIV, let’s be real – the game takes up nearly our entire field of view, making it extremely easy to lose ourselves in the moment. Distractions basically don’t exist unless you really want them to, and when we’re grinding in a desperate last bid to get our relic weapon before Endwalker drops in November, it’s definitely a blessing to be able to focus so entirely on the game. 

Bezels are definitely still visible, especially along the bottom, but because the screen is so big, it’s not something you’re going to notice on a day-to-day basis. Plus, the only logos you’ll find on the front of the display is the Nvidia G-Sync logo, which we would rather not be there. But hey, at least the monitor has G-Sync. 

Just like the last monitor, there’s a little joystick/button combo thing slightly right of center on the bottom of the display. You can press in to open the on-screen menu, where you can change all the usual things you’d want to mess around with on a monitor. You can also flick it to the sides to quickly switch inputs or flick it up and down to quickly change some display settings like brightness and contrast.  

Next to the little joystick thing, there are three recessed buttons. You can use these to save specific settings for up to three different games, which is useful if you’re constantly switching between different types of games – like if you find yourself switching between a competitive FPS like Paladins to a rich and beautiful RPG like Cyberpunk 2077. 

The back of the monitor looks pretty much identical as last year, with an all-white colorway with some futuristic designs etched in. Also returning is the RGB circle around where the stand mounts in the back. The cables go into a little compartment in the bottom of the display, and you get a huge plastic panel that you can slide into it to hide where all the cables go in.

Unfortunately, that’s also where the biggest issue in this monitor’s design arises. Likely because of how heavy this monitor is – and trust us it’s very heavy, the stand doesn’t really have any channels you can use to hide cables. That makes cable management a little bit harder, which is definitely a shame with a monitor of this class. Because anyone who is going to fork over the cash for a monitor of this caliber is probably going to take their desktop appearance pretty seriously – obviously not us, though. 

Now, of course, you can use another stand with this monitor, as it has a standard VESA-compatible mount. However, the massive weight of the monitor gets in the way again, and you’re going to have to make sure you get a stand that can handle it. Honestly, we’d recommend just mounting it on your wall – and when we spoke to Samsung about this display its representatives told us the same thing. 

As far as how many ports are there, though, you get a disappointingly standard array. There are two USB Type-A ports, one USB Type-B cable (to enable the USB passthrough), two HDMI 2.1 ports and one DisplayPort. Samsung includes both an HDMI 2.1 cable and a DisplayPort cable, though if you want to take full advantage of the 240Hz refresh rate you’re going to have to use HDMI 2.1, as the refresh rate will be limited to 120Hz over DP.  

It’s just a bit disappointing that the display inputs are so limited especially given that one of the coolest things about this monitor is its ability to basically emulate two 27-inch 1440p monitors, which would be even more useful with a wider array of connected devices. It would be nice, for instance, to have our PS5, 2 ports for our PC and our Nintendo Switch, so we could easily swap between all of our devices. Oh well, maybe something for next year’s model (if there is one).

It’s hard to overstate just how much this monitor will blow you away the first time you use it. Samsung was somehow able to double the peak brightness over the 1,000 nits in last year’s model to 2,000 in the Samsung Odyssey Neo G9. That gives it an HDR 2000 rating, which is the best HDR you’ll find outside of just playing your PC games on a top-end OLED TV. 

That alone would be impressive, but it  also includes Samsung’s new Quantum Mini LED tech, which is behind its latest QLED TVs. So, the Samsung Odyssey Neo G9 has 2,048 local dimming zones, which is a massive improvement over the measly 10 dimming zones in last year’s model. 

In games like Destiny 2, which is our go-to game to test HDR, the monitor is absolutely stunning. HDR really is a luxury addition, but you’ll never want to give it up when you get it, and the move from the HDR 400 displays we’re usually testing – gaming monitors really need to get their stuff together – an HDR 2000 display like this really is in a whole other world of brightness and color.

Because the Samsung Odyssey Neo G9 isn’t just big and it’s not just a high resolution, it’s also brighter and more colorful than anything you’ve probably ever seen. And, when you combine that with the high refresh rate, it’s kind of a piece of gaming heaven that you’ll definitely want to be part of. But with that high refresh rate and the high resolution, you run into one giant problem: performance.

The Samsung Odyssey Neo G9 has a 5,120 x 1,440 display, which is pretty much 4K. Reviewing this display, we’re using a gaming PC equipped with an Nvidia GeForce RTX 3090, and even then there are not many games where we’re locked at 120 fps on this display, much less 240. 

For instance, in Deathloop, we’re usually hovering around 110 fps, with it often dipping down to 100 or 90 fps. That’s still a fast frame rate, don’t get us wrong, but we’re pretty far off from being able to totally saturate this display. 

Still, with a monitor that costs as much as the Neo G9, you’re going to want to give it some room to grow in the future, and it will be a long time before this monitor’s performance is considered standard.

Buy it if…

You don’t want to compromise
With a 5,120 x 1,440 resolution, a 32:9 aspect ratio, 240Hz refresh rate and HDR 2,000 the Samsung Odyssey Neo G9 is basically the gaming monitor to end all gaming monitors. This is what you get when nothing but the best is acceptable.

You play a lot of MMO and other UI-rich games
If you play a game like Final Fantasy XIV where more screen real estate means more space for buttons and meters, the Samsung Odyssey Neo G9 is great for that.  

You want the latest tech
The Samsung Odyssey Neo G9 is the most top-end gaming monitor that exists right now, and it’s not just because it’s a big screen. With Mini LED and HDR 2,000, this really is a cutting-edge display.

Don’t buy it if…

You’re on any kind of budget
The Samsung Odyssey Neo G9 costs $2,499 (£1,749, AU$2,999). That’s it, that’s all we have to say about that.

You have a smaller desk
Even our giant 5-foot long desk is barely big enough to contain this absolute beast of a gaming monitor. If you have any kind of shortage of space, you’re probably better served by another display.

short review – Hardware on DTF

13 352

This article is a small amateur review of the 21:9 widescreen monitor market (2560×1080 and 3440×1440), as well as a written reflection on choosing a monitor for an upgrade in the near future.

Articles and sections of websites were used in the process of writing /monitor

And also utub, a little Yandex market and pages of some stores.

Initial data . For some time now I have been thinking about gradually upgrading my computer with a 23” 1080 60Hz monitor, and since a complete replacement would be especially expensive, I decided that the first item would be a bunch of monitor + video card, in which the monitor would be the determining point, like hardware, directly setting the requirements for the remaining components. And it was the question of choosing a monitor that sucked in a hell of a hole of time. Initially, I was looking at 27” 1440p 120-144Hz monitors, but then I accidentally stumbled upon the r/ultrawidemasterrace/ subreddit and sure enough… started looking into the 21:9 formatin more detail. On my computer, I mainly play shooters, single-player and pve wankers, with an admixture of non-cybersports pvp components (like battles), which means that viewing angles (like in overwatch) do not threaten me and the 21:9 format is suitable for most of my preferred games and will be helpful. And I still focus on 144 Hz monitors, in which this hertz will be native, and not taken in overclocking with a limitation of other characteristics.

You guys always act like you’re better than me

Current status . Three main manufacturers of matrices for them should start in the matter of choosing a monitor: AU Optronics , Samsung and LG . It is they who determine the main range of characteristics of monitors that are important for the average user: diagonal, resolution, matrix type and screen refresh rate. It is by their plans that we can understand what awaits us in the future in the market. Although the very presence of matrices does not guarantee us that monitor manufacturers will use them in their models. For example, currently there is only one model on the market with a diagonal of approximately 30 “and a resolution of 2560×1080 and a refresh rate of 200 Hz.

In this format, I singled out two main resolutions for myself: budget (in terms of the load on the rest of the hardware) 2560×1080 and “medium boyar” 3440×1440. For brevity, in the future I will call 2560×1080 1080p, and 3440×1440 just 2k. I did not consider 4k and super ultrawides because of money. The diagonals for these resolutions are mostly the same, 34-35 inches. The important point here is the following: with a diagonal of 34 ”and a resolution of 1080p, the ppi of such a monitor is worse than that of a standard 16:9 24”, which can be noticeable with normal media consumption. Since I would like to improve the main characteristics of my new monitor, 1080p at 34″ diagonal I excluded from my list.

After the first runs through sites and articles, I was left with the following set of characteristics: about 30 inches for 1080p and 34-35 for 2k. I still consider VA and IPS matrices equally, since it was not possible to personally compare them.

The first combination is now found only in ACER PREDATOR Z301CBMIPHZX , which is not very easy to find, and it somehow costs not quite budget. In addition, this is a fairly ancient model, and I want the monitor to be a reflection of modern technology. In the near future, the situation will not change much, although new models of this format will appear: Cooler Master GM219-30 , MSI PAG301CR and Sceptre C305B-200UN . All in all, we have few major players and not very intense competition between the old Acer and the upcoming MSI.

Major shifts are taking place in the 2k segment, where 2020 will be very interesting. For quite a long time, the 21:9 format crawled out of 60 Hz, slowly accelerating the old matrices to 75, then 100, then 120 Hz. Even now, if you want native 144Hz, then you have very limited options: LG 34GK950F , the best ultra wide gaming monitor according to rtings, displayninja, which is getting excellent reviews in unison, probably everywhere, it’s not normally sold in Russia yet (only its brother with g-syn and 120 Hz,), options Asus ROG and Acer Predator are like housing in some countries, and fresh models have not yet been delivered. In the year 20, it seems that it will be the right time to purchase such models: native 144Hz become almost the standard for new high-hertz panels, as well as AMD FreeSync support, already released models will reach our market, there will be more monitor manufacturers in this category, there will be no models only in the price category “a little bit did not reach 100k”, but also quite budget alternatives.

Let’s start with the latest: just the other day AOC introduced the CU34G2X with a price tag of 41k. Compare this to 78k for the currently very rare LG 34GK950F (and 68k for the g-sync version at the time of writing): this one model, if the price remains, without competition, may well become the dominant in the segment and attract new consumers. Let’s continue with the models. Alienware AW3420DW (on the same matrix as the previous LG with g-sync) with native 120 Hz and g-sync has not yet reached us, and after that it will cost very decently, MSI OPTIX MPG341CQR is not yet very common and may raise some doubts in the experience of its manufacturer. We will send LENOVO G34W , a relatively new player, to the same category. AOC AGON AG353UCG is built on the same matrix as the predator X35, but it costs not 230k, but 80k, which is already significant progress. That being said, I would like to emphasize that the AOC currently separates the Agon into a separate premium division. From more budget systems from AOC I started above. In general, this is all that I could find so far from what we have either already supplied or in the plans.

What is the result? From my consumer point of view, I see that the market for super wide monitors is developing and advertised by manufacturers (for example, a separate line of LG ultra wide with regular advertising) is much more active. There are high-performance (144 Hz), as well as budget solutions, which is especially nice, and new players in the segment. What I would like to see is more 1080p 30″ models, more activity like Samsung in this segment (which makes sensors but not ultra-wide format models). But, perhaps, the most earnest desire is the support of this format in consoles.

best monitors with G-Sync support for PC

We will tell you about the best monitors that use Nvidia’s excellent adaptive sync technology.

When choosing a new monitor, there are several factors you must consider. Most often, users pay attention to the resolution and screen size, as well as the response time and refresh rate, which is especially important for online and competitive games, and to a lesser extent for casual ones. It’s often worth seeing how the monitor will interact with the PC, and if you have an Nvidia GPU, you definitely need a monitor with G-Sync technology.

G-Sync is a technology developed by Nvidia that focuses on the speed and fluidity of monitors. It synchronizes your display refresh rate with your PC’s in-game rate, which eliminates screen tearing, giving you a crisper, smoother, and overall improved performance and visual experience. At the moment, not every monitor boasts this technology, so when buying a new device, it is better to check for its availability.

Considering the graphics they have to offer, it’s fair to say that G-Sync monitors are extremely well-received, and for that reason we decided to compile a list of the best of them.

It’s worth noting that this year Nvidia graphics cards started supporting FreeSync monitors (an “alternative” to G-Sync technology) via driver loading released in January. This makes the technology a little more open and widespread, but it’s a bit limited at the moment.

1. Asus ROG Swift PG279Q

Best G-Sync Monitor for Gaming

Screen Size: 27″ | Panel type: IPS | Aspect ratio: 16:9 | Resolution: 2560 x 1440 | Response time: 4 ms | Refresh Rate: 144Hz (overclocked to 165Hz) | Weight: 7 kg

This 27-inch monitor has a resolution of 2560×1440, which in our opinion is almost ideal for high-end gaming: it offers much more than a standard FullHD display without being as demanding as like a 4K screen. This results in games that look extremely good and don’t require much GPU power. Plus, you can still get the “regular” refresh rate out of the box that we’ve all gotten used to and is still a bit lacking on 4K screens. And the IPS panel can be overclocked to an ultra-fast 165Hz.

More utilitarian-wise, the monitor inputs include DisplayPort 1.2a as well as HDMI 1.4 (one each), which is a nice addition. If you’re looking for a screen with the best performance at the highest resolution, but without a mind-boggling price tag, then this is the monitor for you. The device will serve you for many years and will provide you with a fast, responsive display with excellent resolution and excellent G-Sync technology.


  • 1440p 144Hz refresh rate, overclocked to 165Hz;
  • Extremely fast refresh and low input lag for an IPS screen.


  • Quite expensive.

2. Asus ROG Swift PG27UQ

Best G-Sync Monitor for 4K HDR Gaming

Screen Size: 27″ | Panel type: IPS | Aspect ratio: 16:9 | Resolution: 3840 x 2160 | Response time: 4 ms | Refresh rate: 144Hz | Weight: 12. 7 kg

This is a great G-Sync monitor with lots of features and features, but it’s a big investment, but we still recommend it as one of the best on the market. This device has an incredibly powerful 27-inch display with stunning 4K resolution and HDR technology for super-sharp visuals, and G-Sync means everything is fluid – even at 144Hz. But this monitor will show the best results if you have a truly powerful PC.

The device has all the ports you need: HDMI 2.0 input, DisplayPort 1.4, 3.5mm audio, and two USB 3.0 ports. The price is really high, which is why users opt for other, cheaper options, but if you have a decent budget and are willing to spend money, then this monitor is what you need.


  • Great design;
  • Really excellent picture quality.


  • Incredibly expensive;
  • Powerful PC required for best results.

3. Acer Predator X27

The Best G-Sync Monitor for Balanced PCs

Panel type: IPS | Aspect ratio: 16:9 | Resolution: 3840 x 2160 | Response time: 4 ms | Refresh rate: 120Hz (overclocked to 144Hz) | Weight: 12. 13 kg

In this case, you can forget about G-Sync, because this is one of the best monitors in general. The use of Nvidia screen technology along with 4K resolution and HDR technology means this beast gives you literally everything. Its 144Hz IPS panel is enhanced with Acer’s own integrated VisionCare technology that aims to protect the retina, plus the device looks damn good.

G-Sync technology allows the monitor to refresh at a variable rate, in sync with the game’s refresh rate, further reducing the chances of tearing. You’ll also have no problem connecting to a range of ports covering the back and left sides: there are two USB 3.0 ports on the sides; on the rear panel there are two more USB 3.0 ports, as well as HDMI 2.0 and DisplayPort 1.4 out. The disadvantage of X27 is the price tag: the device is really very expensive.


  • Bright display with 4K HDR graphics;
  • Has a high refresh rate that can be increased.


  • Response time could be faster;
  • Incredibly expensive.


4. Acer Predator XB321HK

Best G-Sync Monitor for PC with Elite Graphics Card

Screen size: 32 inches | Panel type: IPS | Aspect ratio: 16:9 | Resolution: 3840 x 2160 | Response time: 4 ms | Refresh rate: 60 Hz | Weight: 11.2 kg

A hurdle or problem to overcome when choosing a new screen, especially in 4K, is the trade-off between a higher refresh rate and more pixels. This includes the Acer Predator XB321HK, which has a 60Hz refresh rate, the same as most 4K TVs.

The 32-inch IPS panel is bright and clear, producing vivid images and a screen large enough to make the most of 3840×2160. However, the monitor does not have HDR. Yes, this matters with regard to 4K TVs, but the lack of technology in this device is not a problem, but only reduces its cost. After all, Acer offers a great price for a G-Sync 4K monitor. If the refresh rate compromise doesn’t scare you, it’s still a decent gaming device.


  • Excellent 4K size;
  • Vibrant colors and contrasts.


  • No HDR;
  • Lower update rate than competitors.

5. Alienware AW3418DW

Top Reliable G-Sync Monitor

Panel type: IPS | Aspect ratio: 21:9 | Resolution: 3440 x 1440 | Response time: 4 ms | Refresh rate: 120Hz | Weight: 7.2 kg

The Alienware AW3418DW is a stunning curved monitor. It has a 100Hz refresh rate that can be overclocked up to 120Hz, and has a gorgeous 34-inch display, perfect for beautifully and smoothly playing all the cool new gaming titles.

Alternative: FreeSync Monitors


Best FreeSync Monitor

Screen Size: 2 7 inches | Panel type: IPS | Aspect ratio: 16:9 | Resolution: 2560 x 1440 | Response time: 4 ms | Refresh rate: 144Hz | Weight: 7. 2 kg

This is the best FreeSync monitor because it has no real competition in this area. It’s a 1440p IPS screen with a refresh rate of up to 144Hz and the picture is incredibly smooth. But since the monitor uses the open FreeSync technology instead of G-Sync, the price of the device is not so high.

The monitor’s bezels are nice and thin, which is great. The device itself is solid and allows for a lot of manipulation in terms of height adjustment, tilt, etc. The contrast ratio is also quite large, and the MG279Q offers great support when it comes to ports, so connecting a console is no problem. This is helped by the monitor’s internal scaler, a notable difference between G-Sync and FreeSync panels. The MG279Q is a great monitor and is especially suitable for those who use AMD graphics cards.


  • IPS panel;
  • Refresh rate 144 Hz at 1440p.


  • Very good image quality right out of the box;
  • No blur-free mode;
  • The adaptive refresh range is only 35-90 Hz.

Screen size: 28-inch | Panel type: TN | Aspect ratio: 16:9 | Resolution: 3840 x 2160 | Response time: 1 ms | Refresh rate: 60Hz | Weight: 7.19 kg

The BenQ EL2870U is one of the best monitors on the market. This is a fairly high-quality and reliable display that has 4K and HDR. It also offers an affordable (and quality) path to the latest and greatest gaming screen technology.

Although it has a TN sensor and therefore limited viewing angles, other features make up for this. The response time is competitive with the best devices on the market – it is only 1 ms. Finally, HDR, which the BenQ EL2870U has, is controlled by a single and labeled button that turns the technology on and off. This is generally convenient, and adds another simple level of customization.

Add to that an affordable price and you have one of the best monitors on the market!


  • Affordable 4K HDR;
  • Integrated stereo speakers;
  • Excellent response time.


  • Viewing angles;
  • Low update rate.

Testing gaming monitors

There are two main ways to test a monitor. The first is to play it, which is obvious. Subjective testing of the gaming performance of each panel will not necessarily give you an idea of ​​the technical features of a particular screen, but will allow you to test the functional aspect ratio and various technologies.

Comparing each screen side-by-side to identify subtle differences between each device is incredibly helpful. When you’re only using one monitor, it’s easy to overlook the disadvantages of other monitors. Such testing also allows you to detect and highlight specific problems on each of them.
