Now, since you have quite a diverse selection at this price range, it’s important that you pick the right panel typescreen sizeresolution and refresh rate according to your preference.

Visit our dedicated monitor buyer’s guide for more information.

We’ll cover everything in the monitor summaries below, so as long as you stick to our guidelines and tips, we guarantee that you’ll be satisfied with your new gaming monitor.

However, ensure that your PC system will be able to properly run video games at the resolution and refresh rate you want.

A variable refresh rate (VRR) technology such as AMD FreeSync and NVIDIA G-SYNC can greatly improve performance by synchronizing monitor’s refresh rates to GPU’s frame rates, thus eliminating screen tearing and stuttering with virtually no input lag penalty.

So, for G-SYNC, you will need a compatible NVIDIA graphics card, while FreeSync works with both AMD and select NVIDIA (GTX 10-series or newer) graphics cards.

While most FreeSync monitors we’ve included aren’t officially G-SYNC compatible, some of them offer smooth VRR performance without issues. These are marked as ‘G-SYNC Stable’ for the ‘VRR’ specification in each product box.

VRR on FreeSync monitors marked as ‘Unstable’ work with compatible AMD cards, but won’t have a stable performance. Note that these monitors will otherwise work with NVIDIA cards without issues, except when using FreeSync.

Best 240Hz Gaming Monitor

If you’re looking for a 1080p gaming monitor, you can head over to our best gaming monitors under $200/$300 guide.

The only 1080p displays that are worth over $300 nowadays are the 240Hz+ models and the following monitor offers the best value for the money in that category.

The Pros:

  • FreeSync and MBR up to 280Hz
  • Quick response time speed
  • Fully ergonomic stand
  • Vibrant colors and wide viewing angles

The Cons:

  • Disappointing ELMB-Sync performance

About The Monitor

The ASUS VG259QM is the best 240Hz gaming monitor for serious gamers.

It’s equipped with 240Hz (overclocks to 280Hz), 1ms GtG response time, FreeSync and a backlight strobing technology that can work at the same time as VRR and up to 280Hz!

Moreover, it offers vibrant colors and wide viewing angles.

Image Quality

Thanks to its IPS panel, the ASUS VG259QM delivers vivid and accurate colors that make the colors on TN panels look washed out in comparison.

IPS monitors also have 178° wide viewing angles both horizontally and vertically, so the image quality won’t degrade regardless of the angle you’re looking at the screen.

Further, its rapid 1ms GtG pixel response time speed eliminates any prominent trailing behind fast-moving objects.

Keep in mind that the jump from 144Hz to 240Hz isn’t as noticeable as going from 60Hz to 144Hz, but the difference is there, and it can be crucial for competitive gaming.

So, if you’re a hardcore FPS gamer, this is the monitor for you. However, if you’d rather have a smooth performance as well as a good image quality, there are better options included in this guide.

Features

amd freesync logo

The ASUS VG259QM supports AMD FreeSync with a 48-280Hz VRR range, and NVIDIA certifies it as G-SYNC compatible.

Alternatively, you can use its backlight strobing technology called ELMB-Sync which, unlike most implementations, can operate at the same time as VRR. However, unless you can maintain a constant 200FPS+, there will be noticeable inverse ghosting.

Other useful features include Shadow Boost (for better visibility in darker games), pre-calibrated picture modes (FPS, RTS, RGB, etc.), customizable crosshairs and a refresh rate tracker.

For more information, visit our ASUS VG259QM review.

Design & Connectivity

The stand of the ASUS VG259QM monitors offers height adjustment up to 130mm, tilt by -5°/33°, +/- 90° swivel and pivot and 100x100mm VESA mount compatibility.

Connectivity options include DisplayPort 1.2, two HDMI 2.0 inputs, a headphone jack and two 2W built-in speakers.

Alternatives

If you want a 240Hz gaming monitor that offers a buttery-smooth fast-paced gaming experience but don’t want to sacrifice image quality and viewing angles, the ASUS VG259QM is for you.

Since it has an IPS panel with accurate and consistent colors, it’s also the ideal display for those who want a single monitor for both work and gaming.

In case the VG259QM is not available, check out the MSI MAG251RX or the Dell AW2521HF as alternative 240Hz IPS models.

Best 1440p Gaming Monitors

2560×1440 WQHD resolution provides the perfect pixel-per-inch ratio on 27″ screens. You get plenty of screen space and crystal-clear details without any scaling necessary.

1440p on a 32″ screen offers the same pixel density as 1080p on 24″ displays; you just get a lot bigger screen. Keep in mind that 1440p is also more taxing on your GPU/CPU.

Visit our best 1440p 144Hz gaming monitors buyer’s guide for a more diverse selection.

The Pros:

  • Precise and accurate colors
  • Quick response time speed
  • AMD FreeSync up to 144Hz
  • Ergonomic design

The Cons:

  • Limited FreeSync range over HDMI
  • Design lacks swivel option
  • IPS glow and mediocre contrast ratio (as expected from this panel technology)

About The Monitor

Not a fan of narrow viewing angles and inferior color quality of TN panels, but would like a rapid response time speed as well as a high screen resolution?

The LG 27GL83A is an affordable 27″ 1440p 144Hz 1ms model with an IPS panel!

Image Quality

The LG 27GL83A features an IPS panel with 99% sRGB gamut, so the colors are vibrant, precise and consistent.

Now, when HDR signal is detected, it can also produce a wider ~98% DCI-P3 color gamut for more saturated colors.

Here’s the kicker: it’s also one of the fastest 1440p IPS displays with a rapid 1ms GtG response time speed, meaning that you won’t get any prominent ghosting or motion blur in fast-paced games.

Overall, the LG 27GL83A offers the perfect balance between image quality and performance. You get gorgeous colors, sharp details, a fast response time speed and a high refresh rate.

Features

Besides AMD FreeSync with certified G-SYNC compatibility and VRR range of 48-144Hz, the LG 27GL83A monitor offers plenty of additional features including Black Equalizer, custom crosshairs and pre-calibrated picture presets.

It also supports HDR, though only via software-emulation. For more information, visit our LG 27GL83A review.

Design & Connectivity

Lg 27gl83a back

Connectivity options include DisplayPort 1.4, two HDMI 2.0 ports and a headphone jack. Note that FreeSync is limited to 100Hz over HDMI. With FreeSync disabled, you can get 144Hz at 1440p over HDMI, while DisplayPort supports FreeSync up to 144Hz at 1440p.

The stand of the monitor offers decent ergonomics with up to 110mm height adjustment, -5°/15° tilt, 90° pivot and 100x100mm VESA mount compatibility, but there’s no swivel option. 

Alternatives

If you want a 27″ 1440p 144Hz IPS gaming monitor, the LG 27GL83A is hands-down the best option under $400. The LG 27GP850 is currently on sale for ~$380, so it offers a lot better value for money.

In case you want something a bit better, we recommend the MSI MAG274QRF-QD. It goes for ~$450, but offers a wider Adobe RGB color gamut, MBR and a slightly higher contrast ratio.

The Pros:

  • AMD FreeSync & MBR
  • Wide color gamut
  • Quick response time speed
  • Ergonomic stand and rich connectivity options

The Cons:

  • Design lacks pivot option

About The Monitor

Want a big 32″ gaming monitor?

The Gigabyte M32Q offers an exceptional value for the money. Its price ranges from $400 to $500, but it’s the cheapest 32″ 1440p 144Hz IPS monitor you can find, so we highly recommend investing in it.

Image Quality

Now, because the 2560×1440 resolution is displayed on a larger screen, in this case, you won’t get as much screen space and details as you would 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 quite big and that you will have to sit a bit further from the screen.

Other panel-related specifications include a 1,000:1 contrast ratio, a 350-nit peak brightness (400-nits for HDR Content) and a wide 94% DCI-P3 color gamut (with an sRGB emulation mode provided).

Features

While you can find many 32″ 1440p 144Hz VA monitors below $400, we highly recommend the Gigabyte M32Q instead.

Its 1ms GtG pixel response time speed will ensure you get no visible smearing in fast-paced games. Further, you get stable FreeSync/G-SYNC performance, whereas VRR brightness flickering is common for the VA models.

The Gigabyte M32Q also offers plenty of useful features, including Aim Stabilizer Sync (allows for simultaneous VRR and MBR operation up to 170Hz), various picture presets, Black Equalizer and crosshair overlays.

Design & Connectivity

Gigabyte M32Q Monitor Design

The Gigabyte M32Q has a sturdy stand with up to 130mm height adjustment, +/- 30° swivel, -5°/20° tilt and 100x100mm VESA mount compatibility.

At the back of the monitor, you will two HDMI 2.0 ports, DisplayPort 1.2, a headphone jack, a quad-USB 3.0 hub, USB-C (DP 1.2 Alt Mode) and a built-in KVM switch.

Alternatives

If you’re not sensitive to ghosting and screen tearing and would rather have a higher contrast ratio, check out the Gigabyte G32QCA (curved) and the LG 32GN650 (flat-screen) with VA panels.

Best UltraWide Gaming Monitors

Ultrawide displays have an aspect ratio of 21:9 as opposed to the 16:9 ratio of standard widescreen monitors.

This provides you with extra horizontal space that (in games that support 21:9 natively) widens your field of view for a more immersive gaming experience.

The Pros:

  • Accurate and consistent colors
  • Fast response time speed
  • FreeSync up to 144Hz
  • High pixel density
  • Height-adjustable stand

The Cons:

  • Most users prefer curved screens at this size

About The Monitor

The Sceptre E345B is the best value money ultrawide monitor under $400 as it offers both a high resolution and a fast refresh rate.

Image Quality

3440×1440 resolution hits the pixel density sweet spot on the 34″ screen of the Sceptre E345B monitor.

What does this mean for you?

With roughly 110 pixels per inch, you get plenty of screen space as well as sharp and clear details, without any scaling necessary (roughly the same PPI as 1440p on 27″ monitors).

Further, the monitor has accurate and vivid colors covering the entire sRGB color space, as well as 178° wide viewing angles, decent 300-nit peak brightness and a quick pixel response time speed for no prominent ghosting in fast-paced games.

Features

Moving on, the monitor supports AMD FreeSync with a 48-144Hz VRR range, and it works with compatible NVIDIA cards without any brightness flickering or similar visual artifacts.

Other features include Picture in Picture/Picture by Picture, various picture presets and Motion Blur Reduction.

Design & Connectivity

Sceptre E345B QUT168 Monitor Design

The Sceptre E345B has a height-adjustable stand (up to 130mm). You can also tilt the screen by -5°/15°, swivel by +/- 30° or VESA mount it via the 100x100mm VESA pattern.

Connectivity options include two HDMI 2.0 ports (max 100Hz), two DisplayPort 1.4 inputs, a headphone jack and two 3W speakers.

Alternatives

If you’re looking for a curved 1440p IPS ultrawide monitor, the cheapest model goes for $800, such as the LG 34GP83A.

A VA model can be found for ~$350 with a lower 100Hz refresh rate, such as the Viotek GNV34DB – or for ~$450 with a 144Hz refresh rate and wide color gamut, the AOC CU34G2X.

Best 4K Gaming Monitors

Here, you will find the most affordable 4K UHD monitors. For a more thorough selection, visit our best 4K monitors and best 4K 144Hz monitors buyer’s guides.

Keep in mind that if you’re interested in a 4K monitor for PC gaming, you will need a high-end GPU in order to run newer games at steady ~60FPS at 4K with decent picture settings.

The Pros:

  • Vibrant and rich colors
  • Affordable 4K IPS monitor
  • AMD FreeSync up to 60Hz
  • Fully ergonomic stand

The Cons:

  • Entry-level HDR only

About The Monitor

If you want a 4K gaming monitor with an IPS panel, the ASUS VG289Q is the best option in this price range.

Image Quality

This 28″ monitor provides striking detail clarity and sharpness thanks to its rich pixel density of 157 PPI.

As if that’s not enough, it supports 10-bit color depth (8-bit + 2-bit FRC) and a wide 90% DCI-P3 color gamut for vibrant and consistent colors. For more accurate color output, you can simply use the provided sRGB emulation mode.

As a result, its stunning colors, in addition to 4K UHD resolution, make this monitor great for content creation and consumption, including color-critical work, watching movies, gaming and other multimedia purposes.

Features

It supports AMD FreeSync over both HDMI and DisplayPort with a 40-60Hz VRR range, so it’s great for both PC and console gaming.

Additionally, VRR works with compatible NVIDIA cards without issues, but your mileage may vary here as the monitor is not certified by NVIDIA as ‘G-SYNC Compatible.’

Other features include Shadow Boost (alters the gamma curvature for better visibility of objects in shadows), customizable crosshairs, pre-calibrated picture presets and on-screen timers.

HDR is supported as well, but with a peak brightness of 350-nits, it doesn’t qualify for VESA’s entry-level HDR support.

Regardless, thanks to its wide color gamut, colors will look a bit better on some HDR content, which is actually more than what certain VESA HDR400-certified displays offer!

Design & Connectivity

asus vg289q monitor back

You can adjust the height of the screen by up to 150mm, pivot the screen by 90°, tilt by -5°/20°, swivel by -/+ 62°  and VESA mount it (100x100mm).

Connectivity options include two HDMI 2.0 ports, a single DisplayPort 1.2 input, two 2W integrated speakers and a headphone jack.

The monitor also supports HDCP 2.2, so you’ll be able to watch copy-protected content in native 4K UHD resolution on streaming services such as Netflix.

The Pros:

  • Affordable 32″ 4K monitor
  • High contrast ratio
  • Wide color gamut
  • AMD FreeSync

The Cons:

  • Tilt-only stand
  • Minor ghosting in fast-paced games, mainly in darker scenes

About The Monitor

Nowadays, you can even get a 32″ 4K monitor with a VA panel under 400 USD.

Image Quality

The BenQ EW3270U features a VA panel with a 3,000:1 static contrast ratio and a wide 95% DCI-P3 color gamut.

So, its colors may not be accurate and consistent as that of the IPS models, but you still get an immersive picture quality with vibrant colors and vivid black shades.

But it’s not all good news: you get a slower response time speed, which means there’ll be more trailing and motion blur in fast-paced video games. However, unless you’re playing competitive first-person shooters, the amount of ghosting is tolerable.

Features

The monitor also supports HDR, and even though it has no local dimming, its wide color gamut and high contrast ratio provide a notable boost in image quality for HDR content.

AMD FreeSync is supported as well over both HDMI and DP with a 40-60Hz dynamic range, and it works well with NVIDIA cards.

Design & Connectivity

BenQ EW3270U Monitor Design

The stand of the BenQ EW3270U monitor is tilt-only, but the screen is VESA mount compatible. Connectivity options include two HDMI 2.0 ports, DisplayPort 1.4, a headphone jack, dual 2W integrated speakers, and USB-C (DP 1.4 Alt Mode).

Alternatives

  • LG 32UL500 – A bit cheaper 32″ 4K monitor, but with a slower response time speed
  • LG 32UN650 – A 32″ 4K monitor with an IPS panel, but it goes for ~$450 – $500

Conclusion

Did you find the best gaming monitor under 400 USD for you?

Feel free to leave any questions in the comment section below if you need further assistance. 

On balance, the Sceptre E345B-QUT168 offers the best value/money under $400.

If you don’t want an ultrawide or VA-panel display, the LG 27GP850 or the Gigabyte M32Q are for you.

If you’re a competitive gamer, the ASUS VG259QM offers the best performance.
