best 4K gaming monitor under 400

If you’re after a 4K display, the LG 27UL500 is the best IPS monitor under $400. Keep in mind that it only costs less than $350 when on sale. In case it doesn’t, we recommend the Philips 276E8VJSB as an alternative, although it does not support some features such as compatibility with FreeSync , HDR, or VESA mounts .

We highly recommend saving an additional ~ $70 for the ASUS VG289Q with a wide color gamut, HDR, FreeSync, and fully adjustable stand as the best budget 4K IPS monitor.

Image quality

4K Ultra HD resolution delivers incredible picture quality with maximum detail. The LG 27UL500 is equipped with an IPS panel with 10-bit color support (8-bit + FRC ), 1000: 1 contrast ratio, 300-bit maximum brightness and color space coverage Factory calibrated 98% sRGB .

So not only will the image be crisp and vivid, but it will have vibrant and crisp colors suitable for budding designers.

Unfortunately, PC gaming in 4K is quite demanding, so you need to have a powerful computer or lower the picture settings in some games. A good thing is that due to the high resolution, you won’t need to use anti-aliasing , which will help you improve frame rate performance.

As the LG 27UL500 supports FreeSync, the monitor is better suited for RX Vega 56/64 and Radeon VII cards, as the variable refresh rate can also greatly contribute to performance, although the dynamic refresh rate range is only 40Hz. -60Hz. Other functions such as black stabilizer and dynamic action synchronization are also available.

The display also supports HDR (High Dynamic Range). However, if it can accept HDR signal and display it, it lacks display capabilities like wider color gamut, higher contrast and higher brightness to actually improve the quality of the video, picture. So the HDR image will look washed out most of the time.

This software support for HDR doesn’t really impact the price of the monitor, so it’s more of a gimmick bonus feature than a real reason to buy this display.


As the LG 27UL500 is 27″ in size, the 4K resolution will result in a very high pixel density of around 163 PPI. So everything will be tiny, and you’ll have to scale everything to make the text readable.

Unfortunately, some applications (including some video games) are not to scale, although this is mostly the case with outdated software.

Design and connectivity

The LG 27UL500 4K monitor has a fairly thick frame and is compatible with VESA mounts, but only tilted. Connectivity includes two HDMI 2.0 and DisplayPort 1.2 ports. FreeSync is supported on both DisplayPort and HDMI ports with a range of 40-60Hz. With NVIDIA cards, however, G-SYNC seems to only work in the basic FreeSync range which is 48-60Hz.

2. AOC CQ32G1: The best 32″ curved monitor for gaming under $400

curved monitor for gaming under $400

Want a large 32″ gaming monitor? The AOC CQ32G1 offers exceptional value for money. Note that there is no 32″ 1440p 144Hz model with TN or IPS models, so you’ll have to settle for a VA display if you want a 32″ display.

Image quality

Now, since the 2560 × 1440 resolution is displayed on a larger screen in this case, you won’t have as much space and detail as on a 27″ 1440p monitor.

However, you get a bigger screen which can make the gaming experience more immersive for some users. Keep in mind that a 32″ monitor is large enough and you will need to sit a little further away from the screen.

Other specs related to the display include a 3,000: 1 contrast ratio, 300-bit peak brightness, and a color gamut of around 125% sRGB.

Although the colors of the CQ32G1 are not as precise and consistent as those of the IPS panels, they are rich and vivid, much better than those of any TN model.

The monitor’s 3,000: 1 static contrast ratio results in deep blacks as well as a more vivid relationship between darker and lighter tones.

Alas, when pixels need to switch between colors, they can’t quite keep up with the refresh rate of the monitor. This results in visible drag from fast moving objects, especially noticeable in dark scenes where dark pixels are involved.

Some people can tolerate this phenomenon because in return you get excellent picture quality, but others, who play fast games in competition, will not be able to stand it.

So if you are a casual gamer this shouldn’t be a problem.


The AOC CQ32G1 monitor features motion blur reduction technology which can be activated by setting the Overdrive parameter to “Boost”.

You can also adjust the frequency of the backlight strobes via the “MBR” parameter. This can go a long way in eliminating motion blur, but this feature cannot be enabled at the same time as FreeSync.

FreeSync is supported on both HDMI and DP with 48-144Hz dynamic refresh rate range with stable G-SYNC performance.

Plus, you’ll find pre-calibrated picture presets (FPS, RTS, Racing, and three customizable player profiles) as well as Shadow Control and Game Control for gamma / saturation adjustments.

Design and connectivity

The AOC CQ32G1 has a tilt mount only but it can be mounted to a third party mount via the VESA 100x100mm model. On the back of the monitor you will find HDMI 1.4, HDMI 2.0 and DisplayPort 1.2 inputs as well as an audio jack. The HDMI 1.4 port is limited to 75Hz at 1440p.


The AOC CQ32G1 is the best 32″ 1440p 144Hz gaming monitor you can get for under $400. If you want a similar monitor but with a flat screen instead, check out the LG 32GK650F.

3. LG 32UK550: 4K 32″ monitor with FeeSync

monitor with FeeSync for 400

Today you can even get a 4K monitor for under $400 on 32″, but with a VA panel, not IPS, which has both pros and cons.

Image quality

The LG 32UK550 is equipped with a VA panel with a static contrast ratio of 3000: 1 and a wide color gamut DCI-P3 at 95%. So its colors might not be as accurate and consistent as those of IPS models, but you still get immersive picture quality with rich colors and vivid shades of black.

The problem is, the response time is slower, which means there will be more drag and motion blur in fast-paced video games. However, unless you’re playing first-person shooter games, the ghost count is tolerable.


As for the features, you will find all the standard LG functions such as black stabilizer, screen splitting, on screen control, etc.

The monitor also supports HDR, and while it has no local dimming, its wide color gamut, high contrast ratio, and peak 400-bit brightness can dramatically improve the quality of the screen. image for HDR content, which makes it a great gaming monitor for PS5 and Xbox Series X.

AMD FreeSync is also supported by HDMI and DP systems with dynamic range 40-60Hz, but VRR with NVIDIA cards only works in basic mode (range 48-60Hz).

Design and connectivity

LG 32UK550 monitor stand can be elevated up to 120mm, tilted and VESA mounted. Connectivity options include two HDMI 2.0 ports, DisplayPort 1.2, a headphone jack and two built-in 5W speakers.

The Acer XF252Q is the best 240Hz gaming monitor for serious gamers. It is equipped with 240Hz technology, less than 1ms response time, FreeSync function and backlight strobe technology with strobe frequency up to 240Hz.

Image quality

Since it is based on a TN panel, the Acer XF252Q has narrow viewing angles, which means the image will change color, contrast, and brightness when viewed from oblique angles. But as long as you’re sitting directly in front of the screen, that’s okay with you.

You also won’t get as vivid picture quality as the other gaming monitors included in this guide, which have higher resolutions and IPS or VA panels that offer wider viewing angles and better colors. and better contrast.

But the Acer XF252Q isn’t about image quality, it’s about performance and thanks to its 240Hz refresh rate paired with ~ 0.3ms response time, you’ll get a most responsive gaming experience!

It is based on a new 240Hz TN panel with a native GtG response time of ~ 0.5ms, compared to 1ms for slightly older models. Visit our Acer XF252Q overview for more information.

The Acer XF252Q supports AMD FreeSync with a 48-240Hz VRR range and will work seamlessly with compatible NVIDIA cards.

You can also use its backlight strobe technology called VRB (Visual Response Boost) which can operate at 120Hz, 144Hz and 240Hz; most 240Hz models with MBR can only strobe at 144Hz maximum!

You cannot use the MBR and VRR at the same time, and using the strobe reduces the brightness of the monitor. However, the amount of brightness sacrificed for clarity of movement on the XF252Q is minimal.

Additionally, the monitor offers additional useful gaming features including Black Boost (improves visibility in darker games) and Aim Point (customizable reticle overlay).
