Best Gaming Monitors

• The most important facts in brief
• Gaming monitors are a little more expensive, but they offer better picture quality.
• Not only gaming fans, but also other users can benefit from the advantages of gaming monitors.
• Curved monitors with curved panels offer a more natural viewing experience and make the eyes tire more slowly.
• When selecting the monitor size and resolution, the user’s visual behaviour and ability are very important.

What distinguishes a gaming monitor?

First of all, the fast response time is an important point. Experts also speak of the image build-up time, also called latency. This indicates exactly how long the LCD cells of the monitor need to build up the new images. Since fractions of seconds decide what happens in many computer games, this characteristic is of outstanding importance for most gamers. Of course, a smooth and jerk-free picture also ensures unadulterated viewing pleasure for action films and sports programmes. It is not only gamers who benefit from the fact that graphics card manufacturers such as NVIDIA and AMD use circuit boards as special components that are matched to the graphics cards in the computer. This also ensures particularly fast performance. In addition, the monitor can automatically switch to the correct refresh rate mode set by the graphics card in the computer. Inconsistencies here often lead to jerky images.

The picture quality of gaming monitors is usually significantly better than that of normal monitors, especially in the dark colour range. The simple reason for this is that many action games take place in a dark and threatening environment. Most gaming monitors are also very good at colours and contrasts.

For those who like to use their computers to watch films or live streams of sporting events, the purchase of a gaming monitor is also worth considering. Likewise, all those who attach importance to high quality in the visual display also come into question as a target group. This means that gaming monitors can also show their advantages in image and video editing.

The following table summarises the advantages and disadvantages of gaming monitors:

The terms “cold pressed” or “cold extract” are signs of quality for high-value extra virgin olive oil. A differentiation is made between cold press and cold extract. With both methods, olive oil is extracted from olive pulp at a maximum temperature of 27°C. During cold pressing, olive pulp is compressed in a hydraulic press. This differs from cold extraction, where a centrifuge is used to separate the oil from the fruit pulp through a fast-spinning drum. Cold pressed and cold extract olive oil both have many plus points, as well as a few drawbacks. These are all shown in the following table.

The different panel types

An important distinguishing feature of gaming monitors is the panel type. The panel is the heart of every monitor, because this is where the LCD crystals and, in most models, the backlight are located. As with televisions, there are commonly four different types of panels: the TN panel (Twisted Nematic), the IPS panel (In-Plane Switching), the PVA panel (Patterned Vertical Alignment) and the MVA panel (Multi Vertical Alignment).

TN panel

The differences lie on the one hand in the dependence on the viewing angle. With TN panels, voltage applied causes liquid crystals to rotate polarised light and send it through a filter. Viewers from a more oblique angle cannot see the image as well as with the other types. Therefore, a monitor with this type of panel is good for a solo gamer, because generally the power consumption is lower than the other panels, plus the response time is also faster. And the monitors with this type of panel are also the cheapest.

With both methods, olive oil is extracted from olive pulp at a maximum temperature of 27°C. During cold pressing, olive pulp is compressed in a hydraulic press.

Cold pressed and cold extract olive oil both have many plus points, as well as a few drawbacks. These are all shown in the following table.

IPS-Panel

With IPS panels, the viewing angle dependence is even less than with the VA type. In operation, electrodes lying next to each other align themselves parallel to the screen surface. The black is very powerful and the contrast ratios are very good, but not on the level of VA displays. In dark rooms, there is also the so-called “IPS glow” effect. Seen from a sharp angle, a faint glow is noticeable.

VA-Panels

The VA panel, on the other hand, has a much more stable viewing angle and is therefore very good for TV evenings in a larger group. In operation, vertically arranged molecules align with two polarisers. Other advantages include splendid colour reproduction and sharp contrast. However, with some models, an acute viewing angle has a negative effect on colour representation. The response times of both the MVA variants and the newer PVA panels are lower than those of IPS monitors. In terms of colour and contrast reproduction, the monitors are more efficient than the TN panels.

Gaming monitors with VA panels therefore combine the advantages of TN and IPS panels, which is, however, reflected in a higher purchase price.

4K, WQHD, UWQHD, Curved – what’s the difference?

One of the undisputed most important parameters of a monitor is of course the resolution. A 4K resolution means a fourfold Full HD resolution with about 3,840 x 2,160 pixels, which corresponds to about 8,000,000 pixels. Monitors with WQHD do not resolve quite as high, as they “only” quadruple the 720 pixels of simple HD. Some manufacturers also omit the “W” and just write QHD, but then they mean the same thing. The format is always 16:9. In the ultra variant UWQHD, the format is even 21:9. Accordingly, the vertical resolution is the same as with (W)QHD (i.e. 1,440), only the horizontal is even higher with 3440 instead of 2560 pixels. But even this is not the end of the line: the Samsung CRG9 even offers an aspect ratio of 32:9 and a resolution of 5,120 x 1,440 pixels. The manufacturer thus achieves a very high degree of immersion. However, the space requirement of these ultra-wide screens is also correspondingly large.

What are the advantages of a curved monitor?

As the name suggests, the display of curved monitors is slightly curved. In this way, the manufacturers want to provide a more natural and realistic viewing experience. Gamers speak of “immersion” when they can really immerse themselves in the game world. Since the distance between the eyes and the edges is not so great, the eyes are also supposed to tire more slowly. Curved monitors are increasingly being used not only by gamers, but also in offices where there are usually two monitors side by side at the workplace. For the deep and spatial effect to really come into its own, however, the monitor should be at least 27 inches in size. The degree of curvature is indicated by a number and an “R” for “radius”. A typical value is about 1800R. The curvature is weaker at 1500R and stronger at 2300R. Some models have two video inputs whose content they can show simultaneously. This gives the user two monitors in one.

The special features of gaming monitors

G-Sync

G-Sync is a proprietary technology of the graphics card manufacturer NVIDIA. It automatically adjusts the refresh rate of the monitor to that of the graphics card in the computer and vice versa. This means that the output also depends on the performance characteristics of the monitor. This is to avoid stagnant playback and delays in image processing.

Free Sync

This technology works similarly to G-Sync and comes from the competitor AMD. However, unlike NVIDIA, it does not use a chip for synchronisation, but a specific protocol integrated into the display port. Monitors equipped with FreeSync are often cheaper, but the quality of synchronisation is not as uniformly good as with G-Sync.

Refresh rate

The refresh rate is also called frame rate in some data sheets. The more often the monitor refreshes the image, the smoother the display. A high frame rate is therefore particularly advantageous for fast games. It also makes it easier for the viewer to follow fast camera movements, for example during sports broadcasts. The more fluid motion also makes the picture appear sharper. While refresh rates of 60 hertz used to be standard, 120 hertz or even 144 hertz for top models are now common.

Latency

The signal delay caused by the monitor is called latency or response time and is given in milliseconds. The value given by the manufacturer usually refers to the pixel response time. However, it should be treated with caution because it represents an ideal value that usually only applies to black and grey tones. For colour representations, the latency is often somewhat higher. Naturally, the response time of the monitor is closely related to the refresh rate. If this is 144 hertz, the line-by-line image build-up takes less than half as long as at 60 hertz.

HDR compatibility

Resolution

Resolution is a key characteristic of the monitor. It indicates the width and height of the screen in pixels. For example, a screen with a resolution of 2,560 x 1,440 has 3,686,400 pixels.

Common screen resolutions are 1,920 x 1,080 (also called Full HD), 2560 x 1440 (QHD or WQHD) and 3,840 x 2,160 (UHD or 4K (Ultra HD)). Meanwhile, there are also ultrawide screens with special resolutions such as 2,560 x 1,080 (UW-FHD), 3,440 x 1,440 (UW-QHD), 3,840 x 1,080 (DFHD) and 5,120 x 1,440 (DQHD). A resolution of 1,280 x 720 is already considered HD resolution (HD Ready).

The higher the resolution, the less you can see individual pixels with the naked eye: the sharpness of the picture increases. Since gamers usually sit closer to the screen when playing games than film fans, the advantages of a high resolution are also more readily apparent to them.

But a high resolution is not only an advantage when playing computer games or at the cinema. Those who use a high-resolution monitor in the office literally have more space to arrange windows and applications on the desktop. This is an advantage that is particularly important for graphics programmes and video editing.

Monitor size

The size of the monitor is given in inches. For this purpose, manufacturers measure the diagonal distance from one corner to the other. Gaming monitors have a minimum size of 24 inches; anything less is considered impractical. The usual dimensions range from 24 to 27 inches.

Connections

The connections of the monitors are usually located on the bottom or back. They can be roughly divided into three categories: Video, Audio and Peripherals.

VGA

This 15-pin analogue connection is a bit outdated, but sometimes it is still present. It transmits only the video signal, with resolutions up to a maximum of 3,840 x 2,400 pixels.

DVI

This digital display interface, single- or dual-link DVI (Digital Visual Interface), has a 24-pin connector and also transmits video only. Resolutions up to 1,920 x 1,200 (single) or 2,560 x 1,600 (dual) are supported.

HDMI

This port, which is now widely used, transmits video and audio and is also found on many game consoles.

DisplayPort

The DisplayPort interface provides a very high bandwidth and also transmits video and audio. To take full advantage of its performance, a DisplayPort cable with active electronics is required. Version 1.2 upwards allows several monitors to be cascaded, i.e. wired in series one behind the other.

Line-in

The 3.5 millimetre jack connector as input is only available on a few models. These are monitors with integrated loudspeakers. Connected to the computer’s sound card, the monitor outputs the computer or console sound. Due to the design, the size of the speakers and thus bass is limited, as with flat-screen TVs. Therefore, the use of external speakers or headphones is more common in the gaming scene. The standard is increasingly losing importance, as digital standards such as HDMI or DisplayPort transmit the sound without together with the video signal and without an additional cable.

Headphone output

If available, users can connect headphones to the 3.5-millimetre headphone output. If the sound from the computer or console is usually output via the monitor’s speakers, they can easily redirect it to their headphones.

USB

USB slots directly on the monitor are particularly practical. This way, users can easily connect peripherals such as USB sticks or charge their smartphone. Newer models also potentially have the new USB-C standard.

Thunderbolt 3

Useful additional functions

Apart from the performance of their display, almost all gaming monitors offer additional functions that provide added value for the user. In addition to USB connections, these include built-in speakers, a height-adjustable stand and a space-saving wall mount.

Is it possible to use a gaming monitor as a USB hub?

Thanks to its slots, the monitor can take on the function of a USB hub to which the user can connect the keyboard and mouse if the PC no longer has enough free slots. And even if not everything is occupied there, the USB ports on the monitor are usually much easier to reach. For this to work, the monitor must be connected to the computer via a special USB upstream cable. This is either included in the scope of delivery or can alternatively be purchased by the user. A blue inside on the cable and port indicates that it is a fast USB 3.0 connection. This connection is always preferable for fast data transfer.

In order for the PC to recognise the peripheral devices correctly, some monitor models also require a corresponding entry in the menu. Once this setting has been made, the computer should recognise all devices connected via USB, whether keyboard, mouse, external hard drive or webcam, and supply them with the necessary operating voltage.

Are monitors with built-in speakers useful?

Some models have built-in speakers. This is an advantage if you want to save space or money for external speakers or a whole stereo system. The monitor should have at least two speakers to be able to reproduce at least stereo sound. The technical data sheet states the power consumption in watts. Usually, the higher the wattage, the more powerful the sound. However, even 5-watt speakers, which are relatively powerful for a monitor, cannot be expected to produce the kind of powerful sound that can be achieved with a surround system. This is not possible simply because of the small size of the speakers. For most gaming freaks, the built-in speakers are therefore more of a stopgap solution. In the end, it is your own demands on sound quality that decide whether an external solution is better.

What options are there in terms of position and ergonomics?

Since the user wants to feel comfortable in front of the monitor, ergonomics is an important point that is often neglected in the purchase decision. Practically all gaming monitors offer the tilt function, which allows the tilt to be adjusted up or down. The swivel function means that the monitor can be rotated to the left or right. Some models even allow users to rotate a full 360 degrees around their own axis. The pivot function is particularly interesting for graphic artists because it allows the display to be rotated 90 degrees, i.e. on edge (curved monitors do not offer this option, of course). Gaming monitors with a height-adjustable stand offer another advantage. The user can extend or retract the stand to find the optimal position.

Wall mounting

As with floor stands, there are also wall mounts with tilt, swivel and pivot functions. To increase the distance from the wall if necessary, some wall mounts also offer a movable swivel arm.

Further test reports

Please note: This is a comparison of gaming monitors. We have not subjected the products presented to any tests.

When looking for a test, many users first look at the homepage of the renowned Stiftung Warentest. Here they also find what they are looking for: In a monitor test in August 2019, the testers did not explicitly refer to gaming monitors, but highlighted two models in the test that are particularly suitable for the gamer target group due to their very high speed in image build-up.

These were the 24-inch models Asus VP248HL and Acer ED242QR, both of which scored satisfactory and were in the mid-price segment with a price of just under 300 euros at the time.

The experts of the computer magazine CHIP examined several gaming monitors for testing purposes in January 2020. The winner was the Acer Predator X35. The excellent picture quality, high-quality features and comparatively low power consumption helped it achieve the final grade of “very good” (1.5). The only drawback: the price of well over 2000 euros. The picture quality of the Asus ROG Swift PG27UQ was even better. All in all, it received a final score of 1.6 (“good”), but plays in a similar league in terms of price.

The internet portal techradar also looked at current gaming monitors. Although the experts did not award any grades in their test in October 2020, they did choose the LG UltraGear 38GN950 as the test winner. It offers a 37.5-inch screen diagonal and 160 hertz frame rate. The testers also describe it as extremely responsive. The price is slightly lower than that of CHIP’s test winners.

Second place went to the Samsung CRG9, which even offers an almost unbelievable 49 inch screen diagonal. Thanks to two video inputs, you can also simulate a dual-monitor setup with it. The picture quality is outstanding. The price is well below 1,000 euros.

The testers name the Alienware AW3418DW as the third-best monitor. Alienware is the gaming brand of the renowned computer manufacturer Dell. For an ultrawide monitor, it offers the highest frame rate at 120 hertz and is also very responsive. In terms of price, it ranges from 1,000 to 1,500 euros.

The BenQ PD3200U with 4K resolution came in fifth in the ranking. Originally developed for CAD applications, it can also delight gamers. The testers were particularly impressed by the viewing angle stability.

The AOC CU34G2X also makes it into the techradar top ten. The curved monitor with a 34-inch diagonal captivates gamers with its immersive performance. However, the buyer has to do without G-Sync.

In July 2020, the online magazine techrush took a close look at the Omen 27i, a product from Hewlett Packard‘s gaming range.The fast refresh rate of 165 hertz provides plus points, as do the high resolution (2,560 x 1,440) and the vivid colours. However, the brightness values as well as the contrast sharpness leave something to be desired.
