If money is not an issue and you really want the toughest 4K monitor, then the PG27UQ from Asus is a must.
With a refresh rate of 144 Hz, combined with 4K UHD resolution and G-Sync HDR technology, the Asus ROG Swift PG27UQ can bring some impressive visual effects to your desk. It has an LED backlight that is dynamically controlled over 384 zones and thus offers a very good contrast between light and dark images.
In addition, there is almost perfect color coverage, HDR 10 support with good maximum brightness and extremely low input lag for fast gaming. In addition, it features Quantum Dot technology and a DCI-P3 color space, which offers a 25% wider color range than sRGB monitors, so the monitor can display much more accurate colors. With the latter feature, this 4K bolide is also suitable for video and graphics editing, which justifies the price a little better.
But Asus also goes all out with the design: a very solid base, all ergonomic functions, cool lighting and stylish elements.
So if you want a strong gaming PC (at least GTX 1080 Ti, with other equally powerful components) and really want to have the best 4K experience, then take a look (budget assuming).

As the next “cheaper” alternative to the Asus model above, the Acer Predator XB273K has a very good 4K monitor. With similar features and technical requirements, you get a good price performance for just US$800-1000 less. Nevertheless, the part is very expensive, but if you want G-Sync and 144Hz on an IPS panel with 4K resolution, you currently pay that much.
In any case, the Acer Predator XB3 is an ultra-fast G-Sync HDR gaming monitor that is priced between the premium model Predator X27 and the cheaper Nitro XV3. However, the XB3 is far more powerful than the XV3 and comes close to the screen quality of the much more expensive X27.
As a close relative of the Acer Predator X27, the XB273K has everything the X27 has and only makes slight compromises in terms of HDR quality. Otherwise, it is a sensationally good 4K monitor and much cheaper than other high-end models.
You get really excellent image quality with very good color quality, high contrast and color depth. The 144Hz of the monitor is ideal for faster games and with G-Sync you get the best adaptive synchronization technology for your PC. In addition, there is the extremely low input lag of only 5ms, which means you can even tackle competitive gaming in 4K.
The ergonomic stand is exactly what you would expect from an expensive 4K gaming monitor and with several setting options, it is suitable for everyone. There are also protective covers on the side that are supposed to block annoying rays of the sun or curious glances at LANs.
The XB273K offers you a complete package that you will rarely find. If you have enough budget to buy this monitor (and the PC to run it) don’t waste your time and get one – you won’t regret it.

You really want G-Sync and an IPS panel for your 4K monitor, but you don’t even have over US$1000 lying around? Then take a look at the Acer Predator XB271HK.
The above mentioned Acer and Asus monitors clearly show that monitors with 4K resolution are very expensive. With 4K monitors you almost always have to make a compromise between resolution and refresh rate in the somewhat lower price regions. And that’s exactly what happens here.
Apart from the 60Hz, the Acer Predator XB271HK can still come up with an impressive range of features. The high-quality 27-inch IPS panel gives you bright colors, razor-sharp gaming thanks to G-Sync, low input lag, good gray values and color depth (unfortunately no HDR).
In addition, the design is impressive: the matte coating of the black housing with a thin frame looks great. There is also the stable V-shaped base and a stand that can be tilted, swiveled and rotated. The case can also be removed from the stand using the VESA-compliant mounting holes and an optional wall-mounting kit.
Even if the compromise in the refresh rate and the lack of HDR is unsightly at first glance, it is still a high quality 4K monitor that performs exceptionally well.

- FLEXIBLE CONNECTIVITY: The XG3220 supports laptops, PCs,…
Would you prefer a VA panel with free sync instead of the IPS panels above? Then check out this part!
The XG3220 supports native 4K (2160p) resolution, 60 Hz, HDR10, AMD FreeSync, HDMI 2.0, USB 3.0 and DisplayPort. It comes with a three-year warranty and also includes built-in speakers. This 32-inch monitor can easily replace a television without the need for additional devices – so it is also interesting for console gamers.
The ViewSonic XG3220 also swaps some speed for the number of pixels. Nevertheless, the VA panel offers you an ultra-sharp picture, a good response time of 5 ms and a low input lag of 11 ms. These are good values for an affordable 4K monitor, but eSports pros are probably better off with faster displays. However, if you want to play AAA titles with a resolution of 4K at 60 FPS, then the ViewSonic XG3220 is a top choice.
All content formats look incredibly good on the 4K panel of the XG3220: The colors are rich, as the display has an extended black stabilization, so that even dark games are shown to their best advantage.
HDR is supported here, but not with real 10 bits. For real HDR10, a panel needs a color depth of 10 bits, the XG3220 has 8 bits and uses dithering for the display of 10 bits. This subtle difference is more important to graphic designers than gamers, but it’s still worth noting. It’s also worth noting that a 10-bit monitor costs significantly more than this model (see our recommendations above).
All ergonomic functions for adjusting the display, enough connections and a solid base are standard. In addition, the OSD offers a lot of practical settings, including preset gaming modes for FPS, MOBA or RTS.
5. LG 27UD68
This brings us slowly into the somewhat “cheaper” hemispheres of 4K monitors. The LG 27UD68 is another great 4K gaming monitor in our comparison. It supports Freesync for a smooth picture and its low input delay and motion blur ensure that all games are responsive and immersive. Unfortunately, due to its refresh rate of 60 Hz, it is also less suitable for competitive gaming, but often you don’t want to achieve that with 4K monitors anyway.
In a market where most Ultra HD monitors either look downright boring or not very elegant, the 27UD68 offers a welcome change. But not only the design is convincing here.
To be honest, the LG 27UD68 delivers an excellent performance almost all of the time. This is all the more impressive at the relatively low price when you look at the features: IPS panel, 5ms response time with an input lag of less than 10ms and good brightness as well as free sync.
The colors are excellent and very realistic right from the start. A slight calibration makes them look even better, while the contrast quality, peak brightness and black values are extremely convincing. Since the 27UD68 is an IPS monitor, it offers an excellent wide viewing angle with high color and contrast levels at the same time.
On the whole, LG’s 27UD68 is an absolute bargain for the price. This monitor delivers great color performance, excellent contrast, and some very good gaming features. As long as the missing USB ports don’t bother you, you can access here without hesitation.
6. Samsung UR59C

- CES 2019 INNOVATION Award Winner
- INCREDIBLY VIBRANT AND DARKER BLACKS with 1 billion colors…
- SPLIT SCREEN FUNCTION like PBP (Picture-by-Picture) lets you…
- GAME MODE optimizes image contrast in each game genre
This curved 4K monitor from Samsung is a little cheaper than the model from LG just presented. And the Samsung UR59C is definitely one of the best 4K gaming monitors for anyone who wants a curved display.
The 31.5 inch UR59C is a curved 16: 9 monitor (1500R curve) with a VA panel and a pixel density of 139 pixels per inch. VA panels stand for high contrast and the UR59C definitely does not disappoint with a rate of over 2,500: 1. The Samsung model can also convince in terms of color coverage with 103% volume in the sRGB range; the image is crystal clear thanks to an excellent anti-reflective layer.
The refresh rate is unfortunately a maximum of 60 Hz and there is no adaptive synchronization (like FreeSync or G-Sync). For us gamers this is a little annoying, but to be honest, Samsung doesn’t even explicitly market the UR59C as a gaming monitor. Nevertheless, the part has a fast response time of 4 ms and many tests have shown that the input delay is less than with many other 60 Hz UHD monitors. Unfortunately, there is no precise information about the input lag of the Samsung UR59C, but according to the test by Tomshardware, this should be very low.
At a price of less than US$400, Samsung also has to make savings somewhere. There are further savings with the minimalist stand. This is extremely solid, but also very light and thin. In addition, the screen can only be tilted; there are no vertical or swivel movements here. In addition, you will look in vain for a VESA mount.
Nevertheless, this Samsung monitor is perfect for gaming, because the clarity of the UR59C is first-class due to the high pixel density and high contrast. The benefits of having a wide dynamic range shouldn’t be underestimated – everything looks better. The colors in games are stronger, photos and videos are clearer, and black text on a white background is easier to read. If color accuracy is your priority, this monitor won’t disappoint.
For the best gaming results, set the Samsung Overdrive to maximum and V-Sync to triple buffer mode if possible. Then you will definitely enjoy 4K gaming with the Samsung UR59C (and without ghosting or tearing).

The 32-inch UHD panel of the BenQ EW3270U offers a good price-performance ratio for a monitor in this price range in terms of resolution and screen size. It offers you exact colors, a good grayscale performance, very good contrast values, acceptable brightness (less for HDR content) and good black values. You also get extremely good values for color coverage, which are sufficient even for professional graphic designers.
In addition, reflections are avoided very well, there are no pixel errors and no other problems with flickering or ghosting. For us gamers there is only 60Hz, but still a fast 4ms response time and support for AMD Free-Sync. In addition, there is a very low input lag of 9.4 ms, so at a price of around US$400 you can’t complain here.
Its stand is limited to tilt adjustment, and as is common with more expensive monitors, the downward facing ports on the back are inconveniently placed.
If you have around US$400 budget for a large 4K monitor and you don’t mind the few restrictions, then this is exactly the right choice!
8. BenQ EL2870U
- High resolution 4K monitor: 28-inch LCD TN 3840×2160…
- Eye Care comfort for extended sessions: Proprietary…
- Smooth game play: AMD Free Sync for smooth game play,…
- Get connected: HDMI, DisplayPort input for multi-device…
- Hear the action: built-in speakers x 2, Headphone jack
Finally, our savings tip. The BenQ EL2870U is a 28-inch 4K HDR monitor with a very attractive price, perfect for everyone who wants to test 4K in the first place.
Even if it cannot win a design award and the frame is a bit bulky, the stand offers sufficient stability. Unfortunately, this can only be tilted – no other settings.
The screen is a TN panel, which is always viewed controversially. However, this is quickly forgotten despite the 60Hz, especially since the monitor with its 1ms response time and a sensationally low input lag performs very well in gaming. But also in view of the 4K resolution combined with HDR technology and free sync support.
Of course, you have to cut back on contrast, black levels and the color spectrum, but if you take a closer look at the price, you can overlook it.
In addition, there are the unique BenQ screen technologies that the manufacturer integrates into its panels. The EyeCare technology of the BenQ monitors consists of two parts: Low Blue Light technology, which removes harmful blue light, and intelligent brightness adjustment, with the help of which the EL2870U can automatically change the brightness depending on the environment and color temperature.
If you ask us: At the price, you can’t go wrong here, provided you are looking for a cheap 4K monitor and are willing to accept a few optical losses.
4K Monitors: Things to keep in mind
Whether for gaming, working, your favorite films or creative work – a 4K monitor is a must for some of you. However, the 4K monitors available today are extremely diverse.
Some are designed to deliver fast frame rates and low input lag, which we gamers benefit from. Others are designed for the graphics professional, with extreme color accuracy and support for large areas of color.
Therefore, below you will find everything you need to know about the advantages (and possible pitfalls) of your new 4K monitor. And what else is important before buying.
What is a 4K Monitor?
Any monitor that can produce 4K resolution is called a UHD display (Ultra High Definition). In other words: A 4K monitor can display images with a width of more than 3,840 pixels and 2,160 pixels in the vertical direction (3,840 x 2,160 pixels). This results in twice as many rows and columns of pixels and four times the total number of pixels on a 1080p monitor with the same aspect ratio (16: 9).
These panels are still an expensive choice, but they are becoming increasingly popular. But before we get too into the topic, we should first answer the following key question.
Do I need a 4K Monitor?
Depending on what you use your monitor for most and where you set it up, it may not be worth investing in an expensive 4K monitor for you. Especially since you get a lot more features for less money with a lower resolution screen.
When a 4K monitor is not worthwhile: If you have to turn down the graphics detail settings in games to make it work better in 4K, it will negate much of the 4K benefits. Often you are better advised to use a lower resolution monitor.
Gaming on a 4K Monitor
For starters, let’s take gaming. New games in particular are great to look at in 4K resolution, but the whole thing requires a lot of graphics performance to reach 60 FPS (the minimum for many gamers). Currently, only a handful of the best graphics cards can really reliably provide a 4K screen with enough power for current AAA game titles. And believe us: you want to turn everything up so that the 4K investment pays off.
These graphics cards are the Nvidia GeForce RTX 2080, GeForce RTX 2080 Ti, GeForce RTX 2080 Super, the older GeForce 1080 Ti and the AMD Radeon VII – all very expensive graphics cards, starting at around US$750-800.
If you don’t own any of these cards, playing at 4K will require compromises – and it may not be worth it.
Entertainment on a 4K Monitor
If you only need a 4K monitor for entertainment purposes where PC games are not the focus, a good 4K TV is probably the cheaper option. This is because many 4K TVs are not subject to the same standards as 4K monitors. Such as the need for increased refresh rates (for gaming purposes), high or specialized color accuracy (for graphics work) or low input lag.
So before you buy a 4K monitor: Make sure that you have enough juice for your good colleague so that it is worthwhile.
Why a 4K Monitor could be worth it
With a high resolution like 4K you get a higher level of detail on the monitor with improved textures and more vivid colors. These differences may hardly be noticeable on monitors with a screen diagonal of 27 inches and below, but the 4K resolution comes into its own on larger gaming monitors. This difference depends on the pixel density, which is essentially the number of pixels that are crammed into the display. With an ultra-wide 32 inch monitor with a 1080p resolution, for example, you can slowly start counting the individual pixels. Nobody wants that. In this case, a 4K gaming monitor could be the solution.
Can you even see 4K resolution?
Yes, you read that right. That’s a very relevant question before you just blindly buy a 4K monitor.
When it comes to televisions, the answer to whether or not to choose a 4K model these days is almost always “yes”. Why?
Because we sit much closer to our monitors than to our televisions. It’s not that easy with 4K monitors. So if you really want to take this question seriously, things like algebra, pixel pitch, pixel density, and other complicated things come up on the table. We’ll try to keep it simple.
Whether you can determine the difference in resolution between a 4K panel and, for example, a 1440p panel (with 2,560 x 1,440 pixels) depends on your eyesight, the viewing distance and the screen size.
The tricky thing is that the viewing distance is not uniform because it depends on the size and layout of your desk.
We therefore recommend you: Check out 4K monitors with different screen sizes in a local specialist shop to see whether you can really SEE the difference in the increased pixel density. However, you should be looking at the same image on the screen, which may not always be practical. Still, it’s often the only option you have.
Do you already have a 27-inch monitor with a resolution of 2,560 x 1,440 pixels (1440p) and usually sit around 90 centimeters from the screen? Then a 4K monitor is probably not a sensible “upgrade” for you to justify the costs with the same screen size and distance. It all depends on how big your 4K panel is, how close or far you are sitting, and how well you can see.
Even if not entirely representative (you would need a 4K monitor to really see the differences), you can also watch the following video:
Which panel makes the most sense with 4K Monitors?
- VA panels are one of the oldest display technologies. They often offer the highest contrast ratios and better viewing angles and color rendering compared to TN panels. However, they are also the slowest of all display technologies and therefore usually have the worst response times and input lag values.
- TN screens, on the other hand, are extremely fast in terms of pixel response and average response times of between 1 and 5 milliseconds. They are relatively inexpensive compared to other types of panels, making them ideal for gamers. The tradeoffs are uneven color production, limited viewing angles, and lower contrast ratios. That’s why 4K TN displays are usually only seen in gamer-centric models.
- IPS panels are widely used in 4K monitors. They are usually a little more expensive than VA or TN panels, but they offer the best all-round experience for most users: strong color rendering, moderately fast response times and the widest viewing angles of all display types outside of OLED. However, this comes at a higher price, as IPS models often cost more than the corresponding non-IPS models.
How to buy the right 4K Monitor?
Although 4K monitors are still far from the norm, the top models rely on fast pixel response times and incredibly fast refresh rates. What are the main features to look out for as the technology in the panels (and the GPUs required to provide proper power) continues to advance? Let’s look at it.
There has been a huge development in refresh rates in recent years, especially for monitors with native resolutions below 4K. Monitors with a lower resolution have developed rapidly from 60 Hz (which has long been the standard for “normal” screens) to 144 Hz, 165 Hz and even up to 240 Hz.
Again, it’s more complicated with 4K. Due to the bandwidth limitations of the HDMI 2.0 and DisplayPort 1.4b interfaces and their cables, early 4K monitors were limited to just 60 Hz. However, in recent years several models have been launched that push this cap to 144 Hz (like our two high-end recommendations above).
The input delay is roughly measured as the time it takes your monitor to display an external action. For example, if you fire a weapon with the mouse in Counter Strike, the entry delay, measured in milliseconds, indicates how long it took for the click to appear as an on-screen action.
Some of the best gaming monitors on the market can achieve input delay values of less than 2 ms. But here, too, the whole thing often works differently with 4K displays, especially since the pixel density is much higher.
Newer good 4K monitors like the one we are presenting to you here also achieve values of less than 10 ms, which is perfectly fine.
Not to be confused with the input lag. The response time refers to the time it takes a pixel to switch from black to white or from one shade of gray to another. In practice, you should expect a response time of less than 20 ms even with the slowest 4K panels. When buying a gaming monitor in particular, it is better to aim for a response time of 5 ms or less in order to stay on the ball in the long term.
Adaptive Sync Technologies
Nvidia G-Sync, AMD FreeSync and AMD FreeSync2 are variants of the so-called “Adaptive Sync” technologies. Without delving too deeply into the subject matter – all three are designed to avoid choppy images and smears on the screen. These problems can occur especially in very fast games.
4K monitors often support HDR (High Dynamic Range) content for particularly bright and colorful images. However, you need a monitor with G-Sync Ultimate or FreeSync 2 HDR in order to adaptive sync with HDR games or videos (otherwise you have to select HDR or G-Sync / FreeSync).
Nice to have, of course, but these technologies always result in a surcharge for the respective monitor (especially with G-Sync).
Beware of V-Sync technologies
Note that you need a compatible graphics card to be able to work with G-Sync or FreeSync. A compatible Nvidia GeForce card is required for G-Sync (all newer cards support this), for FreeSync an AMD Radeon card is required. A small group of monitors with the label “G-Sync Compatible” can also use G-Sync technology, although they do not have the specific and exclusive G-Sync-capable circuitry of previous G-Sync versions.
Adjusting the monitor stand may seem unnecessary, but it can affect your comfort – depending on where and how you use the monitor.
A tilt function is quite common, things like panning, height adjustment or even rotating for a portrait format are mostly only found in more expensive models. Think about what you need and see what the respective model can do.
Connectivity is another thing to look at. While an HDMI or DisplayPort input is sufficient for most people and most 4K monitors have both, sometimes you want more than one.
Pay attention to a match with your video source. Some monitors support connection using Thunderbolt 3, which is suitable for certain laptops. This is often only found in non-gaming models.
In order for a 4K monitor to run at over 60 Hz refresh rate, you need a graphics card that can output the signal via a DisplayPort 1.4b cable. With some 4K 144 Hz monitors you even have to connect two of these cables at the same time.
HDR is a color specification that is widely used on modern 4K televisions. With monitors, HDR is still relatively new. On PCs, HDR is available exclusively for 4K monitors and ensures that pictures, videos and games look absolutely spectacular. Of course, you need media that was recorded in HDR or games that support this specification.
However, 4K monitors with true 10-bit HDR are still extremely expensive. So think carefully about whether you really need this feature.
