  • Good value for price
  • Wide color gamut
  • Quick response time speed
  • Plenty of features, including FreeSync and MBR up to 144Hz
  • Height-adjustable stand, USB hub, KVM switch

The Cons:

  • Minor overshoot at low Hz/FPS

About The Monitor

Although $600 might not look ‘budget’ to most gamers – if you want a 4K 144Hz gaming monitor, you won’t find anything below $900. So, the Gigabyte M28U is by far the most affordable model currently available.

Image Quality

The best thing about the Gigabyte M28U is that you’re not really giving up anything crucial for its lower price in comparison to the alternatives.

It’s based on an IPS panel with a wide 94% DCI-P3 color gamut for saturated and rich colors. Next, it has a quick 1ms GtG response time speed that eliminates ghosting behind fast-moving objects, making it ideal for fast-paced gaming.

If you’re using the monitor at a lower refresh rate or at a lower frame rate with VRR (variable refresh rate) enabled, some overshoot is noticeable even with the weakest overdrive applied, but it will be negligible for most gamers.

4K UHD resolution looks incredibly sharp on 28″ sized screens with 157 PPI (pixels per inch), while the wide 178° viewing angles ensure that the image is perfect regardless of the angle you’re looking at the screen.

HDR is supported as well with VESA’s entry-level DisplayHDR 400 certification.

So, you’re not getting the ‘true HDR’ viewing experience for which the monitor would need a much higher peak brightness and many more dimming zones (and would hence also cost more).

Still, thanks to the monitor’s wide color gamut, high 4K UHD resolution, and decent 400-nit peak brightness and 8-zone local dimming, some HDR scenes will look better.

The contrast ratio amounts to 1,000:1, as expected from an IPS monitor, meaning that blacks won’t be as deep as that of VA panels (~3,000:1 contrast ratio). However, there are no 4K 144Hz VA monitors available at this screen size anyway (only 43″).

4:2:0 Color Format

Related:Chroma Subsampling – 4:4:4 vs 4:2:2 vs 4:2:0

On the PS5, HDMI 2.1 is limited to 4:2:0 chroma subsampling on this monitor, even though the PS5 has enough bandwidth for 4:2:2. So, small text displayed on colored backgrounds will look a bit smudgy, but for gaming, this won’t be an issue.

You don’t have to use chroma subsampling over HDMI when using the Xbox Series X or a graphics card with HDMI 2.1.

For the most part, this type of color compression isn’t bothersome for gaming. It’s mainly small text that gets affected and looks a bit smudgy when displayed on colored backgrounds. When just playing games at a normal viewing distance and not deliberately looking for compression artifacts, it looks perfectly fine.

For PC, you can also use DisplayPort 1.4 with DSC (Display Stream Compression) for visually lossless compression if you have a compatible GPU (AMD Navi, NVIDIA Turing, or newer).

When using graphics cards with HDMI 2.1, you can get full 4K 144Hz 4:4:4 without any compression.


Moving on, the Gigabyte M28U supports a variable refresh rate (VRR) for tear-free gameplay up to 144FPS with a 48-144Hz range.

It’s certified as FreeSync Premium Pro for optimal HDR gamut and tone mapping in compatible games. While it doesn’t have NVIDIA’s G-SYNC Compatible certification, it works with GeForce cards without issues.

HDMI 2.1 VRR should also provide a variable refresh rate for the PS5 once the firmware update is available.

Next, Aim Stabilizer is supported, which can reduce perceived motion blur at a cost of picture brightness by backlight strobing.

Other features include Black Equalizer (improves visibility in darker scenes), custom crosshairs, a refresh rate tracker, and an integrated KVM switch that allows you to control multiple devices connected to the screen via one set of keyboard/mouse.

Design & Connectivity

The stand of the monitor is sturdy and offers height adjustment up to 130mm, tilt by -5°/20°, and 100x100mm VESA mount compatibility.

Connectivity options include two HDMI 2.1 ports, DisplayPort 1.4, a USB-C port with DP 1.4 Alt Mode, a USB hub (one upstream and three downstream ports), a headphone jack and dual 3W integrated speakers.

The Pros:

  • DisplayHDR 600
  • Wide color gamut
  • Quick response time speed
  • Plenty of features, including FreeSync and MBR up to 160Hz
  • Ergonomic stand, USB hub

The Cons:

  • IPS glow and mediocre contrast ratio (as expected from this panel technology)
  • Design lacks swivel option

About The Monitor

If you want something better, there’s the LG 27GP950 with improved HDR support.

Image Quality

The LG 27GP950 is based on a Nano IPS panel, which provides an even wider 98% DCI-P3 color gamut for more vibrant colors.

Further, it has VESA’s DisplayHDR 600 certification that implies a higher 600-nit peak brightness for more vivid HDR highlights as well as a local dimming solution (with 16 zones).

These zones can dim parts of the image that needs to be dark without greatly affecting parts that should remain bright, thus further increasing the contrast ratio.

Of course, as there are only 16 zones, this is still far from the ‘true HDR’ viewing experience, but you get a noticeable improvement in comparison to DisplayHDR 400 monitors. HDR scenes with bright and dark objects far apart will look significantly better!

Other panel-related specifications are the same as that of the M28U and include a 1,000:1 static contrast ratio, a fast 1ms response time speed and 178° viewing angles.

The 27″ sized screen is slightly smaller, but it also has a slightly higher pixel density of 163 PPI.

Additionally, you can overclock the LG 27GP950 to 160Hz over DisplayPort.


The LG 27GP950 supports HDMI 2.1 VRR and has both AMD’s FreeSync Premium Pro and NVIDIA’s G-SYNC Compatible certifications for flawless VRR performance within the support range (48-144Hz over DP, 48-120Hz over HDMI).

Other features include various picture presets, Black Stabilizer, and crosshair overlays.

At the back of the monitor, there’s a 48-LED RGB lighting technology that can synchronize with on-screen content or audio and create atmospheric lighting.

Design & Connectivity

LG 27GP950 Monitor Design

The LG 27GP950 features a robust design with up to 110mm height adjustment, -5°/15° tilt, 90° pivot, and 100x100mm VESA mount compatibility. Unlike most monitors with ‘3-side borderless’ designs, the 27GP950 has ultra-thin bezels at all four sides!

Connectivity options include DisplayPort 1.4 with DSC, two HDMI 2.1 inputs, a headphone jack and a dual-USB 3.0 hub.

The Pros:

  • Wide color gamut
  • Quick response time speed
  • Plenty of features, including FreeSync and MBR up to 144Hz
  • Ergonomic stand, USB hub, KVM switch

The Cons:

  • IPS glow and mediocre contrast ratio (as expected from this panel technology)

About The Monitor

If you want a 32″ monitor with 4K UHD resolution and a 144Hz refresh rate, you’re going to love the Gigabyte M32U!

Image Quality

The M32U is based on a fast IPS panel with 1ms GtG pixel response time speed for no prominent ghosting in fast-paced games.

Its color gamut and HDR support aren’t as good as that of the LG 27GP950 with 90% DCI-P3 color space coverage and VESA’s DisplayHDR 400 certification, but the giant 32″ screen does offer a more immersive viewing experience with 4K resolution still offering a high pixel density of 140 PPI.

Even though it only has DisplayHDR 400, there are actually 16 dimming zones that can improve the HDR picture beyond what the usual HDR400 displays can achieve.

Other panel-related specifications include a 350-nit peak brightness (400-nit for HDR content), a 1,000:1 contrast ratio, 178° wide viewing angles and dithered 10-bit color depth support.


Additionally, the Gigabyte M32U supports Aim Stabilizer Sync (simultaneous VRR and MBR operation), Black Equalizer, custom crosshairs and timers, various picture presets and Dashboard (can display PC system parameters on the screen, such as GPU temperature, utilization, etc.).

It has AMD’s FreeSync Premium Pro certification and it works with compatible NVIDIA cards even though it lacks the official ‘G-SYNC Compatible’ badge.

About The Monitor

Need an even larger 4K 144Hz monitor with HDMI 2.1? Gigabyte has you covered with another Aorus model, the FV43U!

Image Quality

The Gigabyte Aorus FV43U is based on a 42.5″ VA panel, so you won’t get as fast response time or wide viewing angles as the IPS models, but you get a higher contrast ratio for deeper blacks!

Due to its slower pixel response time speed, you will be able to notice some ghosting behind fast-moving objects, especially in darker scenes.

However, the FV43U isn’t intended for fast-paced competitive gaming – first of all, due to its huge 43″ screen size. Instead, it excels at providing an immersive viewing and gaming experience.

Of course, it still has low input lag, so you won’t be able to notice any delays between your actions and the result on the screen, allowing you to enjoy casual fast-paced competitive gaming, where the minor ghosting here and there won’t bother you either.

The high 4,000:1 static contrast ratio of the monitor allows for deep blacks and striking details in the shadows of the picture, while the stellar 1,000-nit peak brightness ensures vivid highlights.

On top of that, the Gigabyte FV43U has a wide 99% Adobe RGB color gamut (97% DCI-P3, ~150% sRGB) for exceptionally vibrant colors!

It also supports local dimming, but you’re still not in the ‘true HDR’ category as there are only a few dimming zones. Still, thanks to its wide color gamut, high contrast, and strong peak brightness, HDR image will look great and significantly better than SDR.

The viewing angles aren’t quite as wide as that of IPS technology, so some minor shifts in brightness and contrast can be observed at skewed angles, but nothing extreme or that would take away from the overall viewing immersion.

4K resolution looks very good even on 42.5″ screens with roughly 104 pixels per inch, but if you plan on using the monitor for regular PC use, note that the FV43U has a BGR subpixel layout instead of the regular RGB.

This can make small text look a bit smudgy at native scaling, but there are ways to alleviate it. If you plan on using the screen for a lot of reading and typing, it won’t be ideal – but this is the case with all 43″ monitors and TVs.


VRR is supported via AMD FreeSync Premium Pro and NVIDIA G-SYNC Compatible (though there’s no official certification) within the 48-144Hz range.

Other features include Aim Stabilizer Sync, Black Equalizer, various picture presets and custom crosshairs and timers.

Design & Connectivity

Gigabyte Aorus FV43U Monitor Design

The design is not ergonomic, but it supports VESA mount compatibility via the 200x200mm pattern.

Connectivity options include DisplayPort 1.4 with DSC, two HDMI 2.1 ports, USB-C (with DP Alt Mode), a dual-USB 3.0 hub, a headphone jack, an audio line-out jack, two 12W built-in speakers and a KVM switch.


At the moment, the Gigabyte Aorus FV43U is the only 43″ 4K 144Hz gaming monitor available with HDMI 2.1. You can check out the upcoming models in our New Monitors article. If you’re looking for a big gaming monitor, you should also consider LG’s 48″ OLED TVs as they offer much better performance and image quality at a similar price.

The Pros:

  • DisplayHDR 1400
  • Wide color gamut
  • 1152-zone mini LED FALD backlight
  • Plenty of features, including G-SYNC up to 144Hz
  • Ergonomic stand, USB hub

The Cons:

  • Expensive
  • No HDMI 2.1
  • Noticeable blooming in some scenes
  • Not as fast as some IPS panels

About The Monitor

The ASUS ROG Swift PG32UQX is the best HDR gaming monitor currently available, but it’s quite expensive at $3,000.

Image Quality

What makes this monitor so expensive is its mini LED backlight with an 1152-zone full-array local dimming (FALD) solution.

Unlike the previously mentioned HDR monitors with only several dimming zones, the ASUS PG32UQX has 1152 zones which can precisely dim parts of the screen that need to be dark without affecting the objects that should remain bright.

As a result, you get a significantly higher contrast ratio which along with the monitor’s wide 99% Adobe RGB color gamut and stellar 1400-nit peak brightness results in incredible HDR picture quality.

In some particularly demanding scenes, such as night sky or space filled with small stars, some blooming can be noticed as light from the illuminated zones bleeds into the surrounding dimmed zones.

This blooming or ‘halo effect‘ is expected on FALD displays, so you’ll have to tolerate it in scenes where it occurs. It’s only bothersome in certain scenes, so a lot of users won’t mind it.

OLED displays, on the other hand, don’t have this issue as each pixel is self-illuminated, but they can’t get as bright as LED or mini LED back-lit screens, and they suffer from image retention and the risk of permanent image burn-in. We’ll get more into OLED alternatives later.


Moving on, the ASUS PG32UQX is not as fast as the modern IPS panels. In some scenes, there will be a bit of ghosting noticeable, but to a tolerable degree. You won’t get any smearing associated with slow VA panels though.

Equipped with NVIDIA’s G-SYNC Ultimate module, the PG32UQX offers flawless VRR performance with compatible GeForce cards. You can also use VRR with AMD cards over DisplayPort and with the Xbox Series X over HDMI.

Other features include Dark Boost (improves visibility in darker scenes), various picture presets, Aura Sync RGB lighting, the ROG logo projector, custom crosshairs, timers and a refresh rate tracker.

Further, there’s a light sensor that can automatically adjust screen brightness according to ambient lighting and a small 2-inch OLED panel on the bottom bezel of the screen – it can display PC system parameters and custom gifs.

You can check out our full ASUS PG32UQX review for more information.

Design & Connectivity

ASUS ROG Swift PG32UQX Monitor Design

The stand is quite sturdy and offers height adjustment up to 70mm, swivel by +/- 20°, -5°/20° tilt and 100x100mm VESA mount compatibility.

Connectivity options include DisplayPort 1.4 with DSC, three HDMI 2.0 inputs, a dual-USB 3.0 hub, a headphone jack, and an extra USB 2.0 port at the top of the screen for a webcam.

Note that the HDMI 2.0 inputs on this monitor support 4K 120Hz with 4:2:0 chroma subsampling on the Xbox Series X. On the PS5, you can only get 4K 60Hz or 1080p 120Hz.


For most people, paying $3,000 for a gaming monitor with less than ideal response time speed, no HDMI 2.1, and occasional blooming will not cut it. However, if you want the best 32″ HDR gaming display, there are no alternatives at the moment.

At half the price, you can get a 48″ LG OLED TV with a faster response time speed, HDMI 2.1, and infinite contrast ratio, but it’s not as bright (~800-nit peak) and has the risk of image burn-in. Moreover, most people find 48″ screen too big for regular desktop use.

Alternatively, you might want to wait for LG’s upcoming 42″ OLED TVs. AU Optronics also has a 32″ 4K 144Hz OLED panel under development, but we don’t know how long will it take for it to be implemented in a monitor and available for purchase.

ASUS will also release a 27″ version of this monitor, the PG27UQX with a 576-zone mini LED FALD backlight.

Another 4K 144Hz gaming monitor worth considering is ASUS’ previous flagship model, the PG27UQ. It has a 384-zone FALD solution, so it will have a bit more blooming – but still great HDR image quality. It used to go for $2,000, but can now sometimes be found for ~$1,000. Check out our PG27UQ review for more information.


Did you find the best 4K 144Hz gaming monitor for you? Leave us a comment below if you’re not sure which one to pick!

Overall, the Gigabyte M28U offers exceptional value for money and will completely satisfy most gamers.

If you want something better, both the LG 27GP950 and the Gigabyte M32U are great picks, depending on your preference, and won’t disappoint you.

The Aorus FV43U is for those who care more about immersion than responsiveness, but still want to enjoy a few casual fast-paced and competitive games.

In case budget is not an issue, the ASUS PG32UQX is the best 4K 144Hz HDR gaming monitor currently available, just make sure you are familiar with its flaws and upcoming alternatives before deciding to buy it.
