If you want to get the most out of your games, you need two things: a powerful PC and a corresponding gaming monitor. GIGA has selected a selection of different models for you be it for the tight budget, gaming in 4K resolution or in ultrawide format. We also explain what you need to consider when buying a gaming monitor.

Purchase advice

Strangely enough, many gamers save money on buying the monitor of all things. The screen is crucial here – even with the most powerful gaming computer, poor image quality cannot be compensated for. It is not just the number of pixels that is important here, but also the type of panel installed, the refresh rate and many other factors.

GIGA price tip: Acer Predator XB253QGP

Acer Predator XB253QGP (24.5 inch) "src =" https://games.no1geekfun.com/wp-content/uploads/2021/02/The-best-models-at-a-glance.jpg

Acer Predator XB253QGP (24.5 inches)


  • Top price
  • Adaptive Sync support (up to 144 Hz)
  • Short response time
  • Integrated USB hub


  • Relatively small at 24.5 inches
  • Full HD resolution only
  • Weak HDR effect (HDR 400)

The Acer Predator XB253QGP offers an affordable entry into the world of gaming monitors. For less than 300 euros you get a really successful overall package: an IPS panel with a refresh rate of up to 144 Hz, an extremely short response time and finally Adaptive Sync. Thus, both the FreeSync standard from AMD and G-Sync from Nvidia are supported and unsightly tearing is avoided.

The monitor only has a full HD resolution, which is bearable with a screen diagonal of 24.5 inches. However, if you are looking for a larger monitor, that would be the one for you AOC Gaming C27G1 a good 27-inch alternative. Although G-Sync compatibility was waived here, the model is a bit cheaper overall.

The all-rounder: LG UltraGear 27GL850-B

LG 27GL850-B (27 inch) "src =" https://games.no1geekfun.com/wp-content/uploads/2021/02/1612462963_772_The-best-models-at-a-glance.jpg

LG 27GL850-B (27 inch)


  • Excellent price-performance ratio
  • Adaptive Sync support (up to 144 Hz)
  • Short response time
  • Integrated USB hub


  • Operating in the fastest mode leads to ghosting
  • Weak HDR effect despite HDR10 certification

The LG UltraGear 27GL850-B is a true all-rounder. This gaming monitor with QHD resolution has a 27-inch nano IPS panel and an HDR10 certification, although you shouldn't expect too much from the HDR mode in this price range. It also covers 98 percent of the DCI-P3 color space and the refresh rate of 144 Hz makes it ideal for shooters or the like.

But that wasn't all: The monitor is official "G-Sync Compatible", therefore, owners of both Nvidia and AMD graphics cards can look forward to synchronized frame rates. The main argument in favor of buying the LG UltraGear 27GL850-B, however, is its extremely short response time. This in itself would not be a special feature if it weren't for an IPS panel that normally struggles with precisely this problem.

Note: If you want to achieve the advertised response time of 1 ms, you have to use overdrive, which leads to overshoot artifacts. So we recommend that instead of the "Faster"-Option rather the "Nearly"Variant is selected in the menu. This avoids so-called inverse ghosting without causing excessive motion blur.

The best 4K monitor: Acer Predator XB273KGP

Acer Predator XB273KGP (27 inch) "src =" https://games.no1geekfun.com/wp-content/uploads/2021/02/1612462963_770_The-best-models-at-a-glance.jpg

Acer Predator XB273KGP (27 inch)


  • 4K resolution with up to 144 Hz
  • Adaptive sync support
  • Short response time
  • Integrated USB hub


  • Weak HDR effect (HDR 400)
  • High price

The Acer Predator XB273KGP really has it all. This is not least due to the high price, for which you could theoretically assemble a complete gaming computer. But its equipment leaves little to be desired: 4K resolution, IPS panel, a refresh rate of up to 144 Hz and thanks to Adaptive Sync, both FreeSync and G-Sync are supported.

All in all, this is a really successful overall package. The built-in IPS panel ensures high viewing angle stability and strong colors including HDR functionality. The whole thing is then supplemented with the short response time of theoretically 1 ms, which is caused by the use of the "Visual Response Boost" (VRB) should be made possible. Unfortunately, this feature cannot be used in tandem with FreeSync.

The best ultrawide monitor: Samsung C49RG94SSU

Samsung C49RG94SSU (49 inch) "src =" https://games.no1geekfun.com/wp-content/uploads/2021/02/1612462963_77_The-best-models-at-a-glance.jpg

Samsung C49RG94SSU (49 inch)


  • High ergonomics / immersion thanks to the curved screen
  • Refresh rate of up to 120 Hz
  • FreeSync support
  • HDR 1000
  • Integrated USB hub


  • Assumes sufficient space on the desk
  • Relatively high response time
  • High price

What primarily sets the Samsung C49RG94SSU apart from the competition mentioned so far is its range. In this case, the ultrawide monitor dispenses with the conventional 16: 9 aspect ratio and instead uses a 32: 9 format. This means that the 49-inch device is effectively the size of two 27-inch monitors. The resulting resolution of 5120 x 1440 pixels is between that of a QHD and 4K monitor.

The built-in VA panel ensures the necessary viewing angle stability as well as an accurate color display, which can be increased again if necessary using the HDR 1000 functionality. The maximum refresh rate for this model is 120 Hz. FreeSync is also available. The successor in the form of the Samsung Odyssey G9 goes one step further and comes up with a refresh rate of a full 240 Hz and G-Sync support. But the model is almost twice as expensive.

Overall, the Samsung C49RG94SSU was able to convince in our test, but you should make sure that there is enough space on the desk beforehand. If this screen size is a bit too much for you, you can use the Alienware AW3420DW in the somewhat more compact 21: 9 format as an alternative.

Monitor for esports enthusiasts: Asus ROG Swift PG259QN

ASUS ROG Swift PG259QN (24.5 inch) "src =" https://games.no1geekfun.com/wp-content/uploads/2021/02/1612462963_100_The-best-models-at-a-glance.jpg

ASUS ROG Swift PG259QN (24.5 inch)


  • IPS panel with up to 360 Hz
  • Native G-Sync including reflex technology
  • Measurable latency through "Nvidia Reflex Latency Analyzer"
  • Extremely short response time
  • Integrated USB hub
  • Space-saving table mount included


  • Weak HDR effect (HDR 400)
  • High price

The Asus ROG Swift PG259QN is definitely no ordinary gaming monitor. It is aimed primarily at eSports enthusiasts or those who at least want to feel that way. With a maximum refresh rate of 360 Hz and the extremely short response time of just 1 ms, the monitor easily meets the highest demands. The built-in Nvidia G-Sync processor also allows you to synchronize your frame rates with an Nvidia GPU. The real highlight is the so-called "Nvidia Reflex Latency Analyzer".

The technology takes precise measurements of the respective latencies and then optimizes them again. By then at the latest you will know whether your miserable KD ratio is really due to your hardware or perhaps just a lack of skill on your part. Jokes aside: The Asus ROG Swift PG259QN offers ambitious gamers pure speed in several ways. At a high price of currently over 700 euros, you should think carefully about whether you actually need that much power.

The best gaming monitors: This is how it was chosen

When it comes to gaming monitors, the choice is almost endless these days. As if the decision weren't difficult enough, manufacturers advertise a variety of special functions that are supposed to make gamer hearts beat faster. Some of them make perfect sense, others are just a gimmick. Ultimately, it depends on your individual needs and, above all, your wallet.

In our selection, we deliberately considered models that cover different price segments. So that we can also give you the best possible overview, in addition to our own experience, we have also relied on user ratings and external test institutions.

Buy a monitor: what do I have to consider?

Size, format and screen diagonal

The size of the monitor is of course also a decisive factor. Since you usually sit very close to a monitor, you should think carefully beforehand how big it should be. Common models these days have one Screen diagonal between 24 and 27 inches, so about 61 to 69 cm. If the monitor is too large, it may happen that the game is out of focus.

In addition to the actual size, there are also different formats. The classic among them is still the 16: 9 format. In the meantime, more and more exotic formats such as 21: 9 or 32: 9 by. Where previously several screens were necessary, a single screen in ultrawide format is now sufficient to provide you with the same image area.

If you want to “immerse yourself” completely, you can use the 32: 9 format monitor as an alternative. (Image: GIGA)

Also, because of their enormous size, ultrawide screens are often curved so that content fits more naturally into the human field of vision. This also ensures increased immersion in games without having to look at unsightly edges of the screen. However, this resolution has one catch: There are still a number of games that do not support the format. So this should be considered before making a purchase.

Resolution: 1080p, 1440p or 4K?

When deciding which resolution the gaming monitor should have, your computer and your future upgrade plans should primarily decide. If your PC is not powerful enough to play games in the native resolution of the monitor, a lower resolution screen may be a better choice.

Depending on how your graphics card and monitor handle the upscaling of games in full HD resolution (1920 x 1080 pixels) to 4K (3840 x 2160 pixels), the picture may be slightly blurred The same applies to the opposite way. For the best end result, it is recommended to really use the to use the native resolution of the monitor.

As far as screens with a resolution of 1440p (QHD) or 4K (UHD) are concerned, these are still a lot more expensive than variants with Full HD. It is therefore also advisable to always make the question of resolution dependent on your budget.

TN, IPS or VA: advantages and disadvantages of the panels

As far as the built-in panel of a monitor is concerned, there is unfortunately no general answer as to which of these is the best. Each panel has its advantages and disadvantages that must be weighed up. The following overview therefore shows the most important differences between Twisted Nemantic (TN), In plane switching (IPS) and Vertical alignment (VA) listed:

  • TN: Due to their construction, such displays are still the cheapest and also have the shortest response time. In return, however, their image quality and viewing angle stability suffer.
  • IPS: Models with an IPS panel, however, are pretty much the exact opposite. They shine with excellent image quality and viewing angle stability, but are significantly more expensive and have slower response times.
  • VA: These displays represent a compromise between the two types mentioned above. The picture quality is better than that of TN panels, but does not come close to that of an IPS panel. The situation is similar with the response time, since it is less than that of IPS displays, but still doesn't come close to that of a fast TN panel.

Response time, contrast & input lag

With a flat screen monitor you were well prepared for the next LAN party. With the boom in LCD technology, however, certain downsides came to the fore, which posed a problem for gamers in particular: ghosting (dragging images), washed-out black that could only pass through as dark gray and so-called "image enhancement" functions that were too massive Input lag.

Fortunately, nowadays you don't have to worry about it if you buy the monitor from a well-known manufacturer. Even inexpensive monitors have a response time of 6 milliseconds and come up with a static contrast value of over 1000: 1.

Refresh rate: 60, 144, 240 or 360 Hz?

The first important question that gamers should ask themselves when purchasing a new gaming monitor: What refresh rate (Hz) do I need? This decision in turn depends on how many frames per second (FPS) you would like to gamble with in the ideal case. fact is that Games appear much more fluid to the human eye, the more FPS are currently displayed.

So what does the refresh rate have to do with the FPS? Quite simply, let's take a monitor with 60 Hz: This can easily display up to 60 images per second. If the FPS of the respective game is now significantly below or above the refresh rate of the monitor, it can lead to jerking or unsightly artifact formation (tearing).

This is what screen tearing could look like using The Witcher 3: Wild Hunt as an example. (Image: CD Projekt Red)

Before making your decision, you should also consider the performance of your computer and the type of games that you mainly play. Shooters, especially in the eSport sector, benefit most from increased frame rates. These are often graphically less demanding titles that crack the magical limit of 144 FPS without any problems, even with average hardware. In such a case, a correspondingly fast monitor with 144 Hz, 240 Hz or even 360 Hz is definitely worthwhile.

G-Sync and FreeSync: a must or just a gimmick?

One problem that high FPS numbers often lead to is the aforementioned artifact formation also called screen tearing. For a long time, the only solution was the use of Vsync. Unfortunately, often at the cost of increased input lag and overall less FPS. In the meantime, manufacturers such as Nvidia and AMD have developed their own solutions: G-Sync and FreeSync. Both technologies work in a similar way and ensure that the Images of the graphics card are synchronized with the refresh rate of the monitor will.

Basically, it makes perfect sense to opt for a device with one of the technologies mentioned. The two standards are now relatively widespread, making monitors much more affordable. For a long time G-Sync was only compatible with Nvidia graphics cards and FreeSync was therefore reserved for AMD cards. In the meantime, however, many monitors have so-called "Adaptive Sync" and therefore support both standards.

Nvidia Reflex: What the technology is all about

With Nvidia Reflex, the hardware giant is taking a further step in order to once again optimize the gaming experience of eSports enthusiasts and shooter enthusiasts in particular. The new technology is linked to several interfaces, all of which are dedicated to the analysis and reduction of all potentially occurring latencies. The following video explains the principle behind the technology in detail:

The aim is to determine how long it actually takes from the mouse click to the action visible on your monitor. So far, such values ​​could only be measured with the help of expensive special cameras. That should change in the future. It should be noted, however, that you need suitable hardware for this – both the monitor and your mouse must be compatible with Nvidia Reflex. You also need an Nvidia GPU of the 900 series or newer. After all, not every game is compatible with the new technology: Currently these are Apex Legends, Valorant or Fortnite, among others.

Which monitor is right for me?

By now it should have become clear how much a qualitative monitor makes a difference. So now it's time to decide on a model. Unfortunately, there is no universal formula for this, as the choice of a monitor depends heavily on your individual requirements. Still, there are a few scenarios where certain monitors are better suited than others:

  • Do you mainly play shooters and maybe competitively? The image quality is also far from being as important to you as precise inputs and maximum FPS? In this case, a monitor with a fast TN panel and a correspondingly high refresh rate beyond 144 Hz is suitable. Ideally, the monitor also has G-Sync or FreeSync. If you really want to get the absolute maximum in precision, opt for a model with the so-called Nvidia reflex technology for measuring and reducing the input lag.
  • Stands for you appealing graphics in the foregroundthat lets you immerse yourself completely in the game? Here you can either use a monitor in 4K resolution or a model in ultrawide format (21: 9 or 32: 9). However, both options require a powerful graphics card due to the increased pixel density. This should be included in the price before making a purchase.
  • You prefer to grab yours Controller and then play comfortably from the bed or sofa? If you have the budget, you can go to one "Big format gaming display" (BFGD) take hold. Usually a corresponding gaming television would be much cheaper and almost as good.
