The Gigabyte M32U is a 32 inch 4k monitor with a fast 144Hz refresh rate. It's very similar to the smaller Gigabyte M28U, but there are some minor differences between them. It's one of the few monitors with HDMI 2.1 ports, making it an excellent choice for console gamers, as it can take full advantage of most of what the Sony PS5 and Xbox Series S|X have to offer, including 4k @ 120Hz gaming. It also has a few extra features designed for productivity, including a built-in keyboard video and mouse switch (KVM), so you can control two sources with a single keyboard and mouse. The large, high-resolution screen is great for multitasking and delivers superb text clarity. Unfortunately, it has a low contrast ratio, and although there's a local dimming feature, it's terrible, so it's not a good choice for a dark room, and the sRGB mode, which is the most accurate one out of the box, locks down almost all settings.

The Gigabyte M32U is an impressive gaming monitor. One of the few monitors with HDMI 2.1, it's a great choice for Xbox Series X and PS5 gamers. It has a great selection of additional features that help it stand out against the competition, and along with the smaller Gigabyte M28U, it's one of the best 4k monitors we've tested.

For more options, check out our recommendations for the best monitors for PS5, the best monitors for Xbox Series X, and the best gaming monitors.

Gigabyte M28U

The Gigabyte M32U is a bit better than the Gigabyte M28U. Although these two monitors are very similar overall, the larger model has better ergonomics and a better response time. The M28U has worse overshoot in every overdrive mode, especially when gaming at 60Hz. On the other hand, the M28U has better reflection handling, but it's not a significant difference.

Gigabyte AORUS FI32U

The Gigabyte M32U and the Gigabyte AORUS FI32U offer nearly identical performance. The FI32U has a more versatile stand, as you can rotate it to portrait orientation. The FI32U also has a few extra built-in gaming features, including a unique active noise cancelling feature for your microphone. Overall, they perform about the same, but the extra features differ. If your main use is for the office/productivity, the M32U is a better choice. If your main use is gaming, the FI32U is a better choice.

Samsung Odyssey G7 LC32G75T

The Samsung Odyssey G7 LC32G75T and the Gigabyte M32U are both excellent gaming monitors, but the better one depends a bit on your personal preferences. The Samsung uses a VA panel, and it's a better choice for a dark room. The Gigabyte has an IPS panel, so it's best for a brighter viewing environment. The Gigabyte also has better viewing angles, and it supports HDMI 2.1, so it's a better choice for Sony PS5 or Xbox Series S|X gamers.

Gigabyte M32Q

The Gigabyte M32U is a bit better overall than the Gigabyte M32Q. The M32U has a higher resolution screen, resulting in better text clarity thanks to the higher pixel density. The M32U has two HDMI 2.1 ports, making it a better choice for Xbox Series S|X or PS5 gamers.

Dell G3223Q

The Dell G3223Q and the Gigabyte M32U are both excellent 4k gaming monitors. They're very similar overall as they each have a 144Hz refresh rate, HDMI 2.1 bandwidth, and a quick response time, but the Gigabyte has a backlight strobing feature, which the Dell doesn't have. However, the Dell gets brighter, so it's better for well-lit rooms, and the out-of-the-box accuracy is much better, too.

Gigabyte M32UC

The Gigabyte M32U and the Gigabyte M32UC offer very similar overall performance, but the best one depends mainly on your viewing conditions. The M32U is better for most people as it has better ergonomics, better viewing angles, and better motion handling with very little black smear. The M32UC specifically targets users in a dark or dim room, as it has a much better contrast ratio, resulting in deeper, more uniform blacks in a dark room.

LG 32GQ950-B

The LG 32GQ950-B is a bit better than the Gigabyte M32U. The LG has a higher max refresh rate through an optional overclock, and it delivers better motion handling at all refresh rates, with less blur behind fast-moving objects. The LG also has full bandwidth HDMI 2.1 ports, whereas the Gigabyte relies on compression to achieve the highest formats. This isn't an issue for most sources, but the LG looks a bit better on sources that don't support the latest display stream compression format, including the PS5.

Samsung Odyssey Neo G7 S32BG75

The Gigabyte M32U and the Samsung Odyssey Neo G7 S32BG75 are both 4k, 32-inch gaming monitors with a few advantages and disadvantages. The Gigabyte is the better choice if you want something for co-op gaming as it has wide viewing angles, while the Samsung performs better in dark rooms as it has improved local dimming and better contrast. The Samsung also has a quicker response time with low-frame-rate content, but there's flicker when the frame rate drops too low.

Samsung Odyssey G7 S28AG70

The Gigabyte M32U and the Samsung Odyssey G7 S28AG70 are both excellent 4k gaming monitors. They have many of the same features with a 144Hz refresh rate and native FreeSync support, but the Gigabyte has better motion handling as the response time is much better at 60Hz. However, the HDMI 2.1 inputs on the Samsung support more bandwidth than those on the Gigabyte, as they can support up to 40 Gbps while the Gigabyte is 24 Gbps. This means that you don't need Display Stream Compression for 4k gaming at 120 fps from certain sources on the Samsung, like from the Xbox Series X.

LG 27GP950-B

The Gigabyte M32U is a bit better than the LG 27GP950-B overall. The Gigabyte has much better reflection handling, so it's better able to overcome glare in a bright room. The Gigabyte also has better black uniformity and better ergonomics. On the other hand, the LG is a lot brighter in HDR, and it can display a wider color gamut.

Samsung Odyssey Neo G8 S32BG85

The Gigabyte M32U and the Samsung Odyssey Neo G8 S32BG85 are both excellent gaming monitors with a few differences. The Samsung is better for dark room gaming as it delivers deeper blacks and has a better local dimming feature. It also has a higher 240Hz refresh rate if you want to use it for high-frame-rate gaming. However, the Gigabyte has wider viewing angles if you want to use it for co-op gaming, and it's more versatile for productivity if you need something for work and play.

Dell U3223QE

The Dell U3223QE and the Gigabyte M32U are different types of 4k monitors. The Dell is focused on office use with a USB hub with more inputs than the Gigabyte, although the Gigabyte offers the same features, like DisplayPort Alt Mode and a KVM switch. The Dell also has much better ergonomics as you can rotate it into portrait mode. However, the Gigabyte is focused on gaming as it has a 144Hz refresh rate with HDMI 2.1 bandwidth and VRR support, allowing you to play games at high framerates from PCs and consoles without issue.

Gigabyte M27Q

The Gigabyte M32U is a bit better than the Gigabyte M27Q. The M32U has a larger, higher-resolution screen, resulting in much better text clarity, and it has better ergonomics. The M32U also has two HDMI 2.1 ports, making it a better choice for Sony PS5 or Xbox Series S|X gamers.

Sony INZONE M9

The Gigabyte M32U is slightly better than the Sony INZONE M9 overall. The Gigabyte is a more versatile monitor overall, with much better ergonomics, better accuracy out of the box, and a slightly faster response time. The Sony monitor, on the other hand, delivers a better HDR experience overall. The Sony gets brighter in HDR and has a much better local dimming feature.

Acer Nitro XV282K KVbmiipruzx

The Acer Nitro XV282K KVbmiipruzx and the Gigabyte M32U are extremely similar overall. The Gigabyte has a larger screen, so text is slightly less sharp due to the lower pixel density. The Acer has better ergonomics, so it's more versatile and easier to place in an ideal viewing position. The Gigabyte has a few extra features that make it a better choice for office users, including a built-in KVM.

Gigabyte AORUS FV43U

The Gigabyte M32U and the Gigabyte AORUS FV43U use different panel technologies, each with strengths and weaknesses. The M32U has a smaller IPS panel, which delivers wide viewing angles. The M32U has a much faster response time at 60Hz. The FV43U, on the other hand, has a larger screen with much better contrast and better uniformity, so it's a better choice for a dim or dark room.

BenQ EW3270U

The Gigabyte M32U and the BenQ EW3270U use different panel technologies, but the Gigabyte is still better for most people overall. The Gigabyte has a much faster refresh rate, significantly better motion handling, and lower input lag. The Gigabyte has better ergonomics, and it has two HDMI 2.1 ports, so it's a better choice for some console gamers. On the other hand, the BenQ has much better contrast, so if you're in a dark room and the other things don't matter to you, it's a better choice.

LG 27GN950-B

The Gigabyte M32U is better overall than the LG 27GN950-B. The Gigabyte has a larger screen, which results in slightly worse text clarity, but it has better black uniformity, much better reflection handling, and better ergonomics. The Gigabyte is better for PS5 and Xbox Series S|X gamers, as it has two HDMI 2.1 ports and supports 4k @ 120Hz gaming over HDMI, while the LG can only do so over DisplayPort from a PC.

ASUS ROG Strix XG27UQ

The ASUS ROG Strix XG27UQ and the Gigabyte M32U are very similar overall. The ASUS has better ergonomics, but the Gigabyte has slightly better viewing angles. The biggest difference between them is the inputs, as the Gigabyte has two HDMI 2.1 ports, whereas the ASUS is limited to HDMI 2.0, and can only reach its maximum resolution and refresh rate over DisplayPort. This makes the Gigabyte a better choice for console gamers.

Gigabyte G27Q

The Gigabyte M32U is much better than the Gigabyte G27Q. The M32U has a larger, higher-resolution screen, resulting in better text clarity, and it has a faster response time, especially at 60Hz. The biggest difference is in the inputs, though, as the M32U has two HDMI 2.1 ports, making it a much better choice for PS5 or Xbox Series S|X gamers.

LG 48 C1 OLED

The LG 48 C1 OLED and the Gigabyte M32U are very different displays with different target audiences. The LG is a large TV that we tested as a monitor that has an OLED panel. The OLED panel delivers a nearly instantaneous response time, with wide viewing angles and perfect blacks. The large screen isn't meant to be used as a desktop monitor, though, and there's a risk of permanent burn-in. Although the Gigabyte doesn't perform as well overall, it's a more traditional form factor that fits on most desks, and there's no chance of burn-in.

Corsair XENEON 32QHD165

The Gigabyte M32U is a bit better than the Corsair XENEON 32QHD165. The Gigabyte has a higher resolution screen, resulting in much better text clarity and a sharper image. The Gigabyte also has slightly better ergonomics, with a better height adjustment, and tons of extra features, including a built-in KVM (Keyboard, Video, Mouse) switch, so you can control two computers with a single set of input devices. Finally, the Gigabyte is better for console gamers, as it has two HDMI 2.1 ports and supports 4k @ 120Hz gaming.

Apple Studio Display

The Gigabyte M32U is a better all-around monitor than the Apple Studio Display, but they're for different uses. The Gigabyte is a 4k gaming monitor with HDMI 2.1 bandwidth, so it's a great choice for console gaming up to 120 fps. It also has more inputs like HDMI and DisplayPort, and it supports HDR, which the Apple monitor doesn't have. On the other hand, the Apple is a 5k monitor meant for macOS users, and it has significantly better reflection handling, meaning it performs better in well-lit rooms.

The Gigabyte M32U is identical to the smaller Gigabyte M28U. It has a slightly understated design, with thin bezels on three sides and a flat base that supports the monitor well but takes up a bit more space overall. The back of the monitor has a bit more flash to it, with a glossy section near the top but no RGB bias lighting or other gamer aesthetic.

Build Quality

The Gigabyte M32U has good overall build quality, nearly identical to the Gigabyte M28U and the other Gigabyte monitors we've tested. It's entirely plastic, with no metal components, which is a bit disappointing, but the plastic seems to be decent quality. There's a little bit of flex on the back panel, but otherwise, it's pretty solid. We noticed a strange clicking noise occasionally when the black frame insertion feature is enabled at the same time as the variable refresh rate feature and the framerate changes. We haven't seen other reports of this issue, so it could just be our unit.

The Gigabyte M32U has good ergonomics. Unlike the smaller Gigabyte M28U, it can swivel in either direction, which is great, but everything else is the same. Other than a glossy section at the top and the Gigabyte logo and model number, the back of the monitor is a bit plain. There's a cutout in the stand for basic cable management. If you want something with even better ergonomics, then check out the Dell U3223QE.

As expected for an IPS monitor, the Gigabyte M32U has mediocre contrast, so blacks look gray in a dark room. Contrast can vary between individual units, but this is close to the upper limits of what we expect from an IPS panel. Unfortunately, the local dimming feature can't improve the contrast ratio at all. If you want a 4k monitor with a much better contrast, then look into the Samsung Odyssey Neo G7 S32BG75.

Unfortunately, although the Gigabyte M32U has a local dimming feature, it's terrible. In most content, it doesn't appear to do anything. It's edge-lit, with approximately 16 dimming zones, so even when the local dimming is working, because each zone is so large, transitions are very noticeable and distracting.

Enabling the Local Dimming features locks out a few settings. It enables DCR, which noticeably changes the gamma curve and locks the brightness at maximum.

The Gigabyte M32U has just alright peak brightness in HDR. It's bright enough that most games look good, but it's not bright enough for a true cinematic experience. Small highlights in some scenes aren't bright enough to stand out. On the other hand, there's very little difference in peak brightness with different scenes, which is great. Unfortunately, the peak brightness doesn't track the EOTF very well, as near-black areas are brighter than they should be, and all other scenes are a bit too dim. The brightness cuts off sharply at the monitor's peak brightness, causing a loss of fine details in bright areas.

These measurements were taken before calibration, with HDR enabled, with local dimming on.

Unfortunately, the Gigabyte M32U has just passable black uniformity. There's quite a bit of cloudiness throughout the screen, and significant backlight bleed along the top and bottom edge. Local dimming helps to reduce the cloudiness of the screen to the left and right of the test cross but doesn't reduce the amount of backlight bleed, which suggests that the local dimming isn't fully turning those zones off.

The Gigabyte M32U has excellent accuracy out of the box. Gamma follows the sRGB curve but levels out close to 2.1 above a 20% stimulus, so most scenes are a bit too bright. The white balance is great, and the color temperature is very close to the calibration target. There are no significant issues with any color, but reds are oversaturated a bit.

Out of the box, the most accurate picture mode is the sRGB mode. Unfortunately, this mode brings some limitations; all settings except for the brightness are locked down and can't be changed, including the color temperature and overdrive setting, which is locked to 'Smart OD'. If you prefer a picture mode with unlocked settings, the 'Custom 1' mode delivers the second-best results, but colors are oversaturated.

After calibration, the Gigabyte M32U has outstanding accuracy, with no noticeable issues at all. White balance and colors are nearly perfect, and any remaining inaccuracies aren't noticeable without a colorimeter. Gamma is much closer to the sRGB target curve, except for a slight dip in really bright scenes. Despite how accurate it is out of the box, the M32U might be worth calibrating for some people, as it allows you to achieve fantastic accuracy without the limitations of the sRGB mode.

The Gigabyte M32U has an outstanding SDR color gamut, but it's not as good as the Corsair XENEON 32QHD165. It can display the entire sRGB color space used by most current desktop and web content, so you shouldn't notice any issues there. For professional content creators, it has great coverage of the Adobe RGB color space. It has limited coverage of greens in that color space, which might disappoint some users.

The Gigabyte M32U has fantastic gradient handling. There's almost no banding in any shade.

Although advertised as an 8-bit panel, this model accepts a 10-bit signal and displays it well, so it's most likely using dithering to approximate a 10-bit panel. It's also known as 8-bit + FRC.

The Gigabyte M32U has a fast refresh rate, great for gamers. Thanks to the inclusion of HDMI 2.1 bandwidth ports, there's no difference in the supported formats between DisplayPort and HDMI, as long as you're using a source that supports HDMI 2.1 bandwidth. If you're using a graphics card that only supports HDMI 2.0 bandwidth, the supported formats are a bit different over HDMI. You can read more about what to expect and what's supported in the additional review notes we posted for the Gigabyte M28U, which are also valid for this monitor. Unlike the Gigabyte M32UC, there's no optional overclock to 160Hz.

The Gigabyte M32U has an incredible response time, resulting in crystal-clear motion with almost no noticeable blur behind fast-moving objects. Like most monitors, it has an adjustable Overdrive setting. We recommend the 'Picture Quality' setting, as it delivers the best overall performance with the least amount of overshoot. 'Balance' is slightly faster, but there's significantly more overshoot that may bother some people. If you prefer inverse ghosting over motion blur, go with that mode instead. The 'Speed' setting delivers the fastest rise/fall time, but there's terrible overshoot and significant inverse ghosting, so we don't recommend it.

The M32U features a 'Smart OD' mode that's advertised to automatically select the best overdrive mode, so you don't have to worry about switching modes if you switch sources or switch to a lower refresh rate. At both 144Hz and 60Hz, it appears to be in the 'Balance' mode, so we're not sure if it's doing anything.

The Gigabyte M32U has an excellent response time when gaming at 120Hz, like when gaming on a PS5 or Xbox Series X. The overall performance is nearly identical to when gaming at the max refresh rate, but there's a bit more overshoot, especially in dark areas. The recommended Overdrive setting is still 'Picture Quality', for the same reasons as at the max refresh rate.

The Gigabyte M32U has a very good response time at 60Hz, a bit better than the Gigabyte M28U. We recommend the 'Off' Overdrive setting, as it performs the best overall at 60Hz, but if you're looking for a set-and-forget setting that works well at any refresh rate, 'Picture Quality' is almost as good at 60Hz as at the max refresh rate. There's more noticeable overshoot in each mode than at the max refresh rate, but it's not too bad with the 'Picture Quality' setting. We didn't notice the same strange overshoot behavior that we noticed on the M28U, which is great.

The Gigabyte M32U has an optional backlight strobing feature, commonly known as black frame insertion (BFI), to help reduce blur. Unlike most monitors, the M32U supports BFI even with the variable refresh rate (VRR) feature. With VRR disabled, BFI is only available at 120Hz or 144Hz.

Unfortunately, the BFI feature is a bit buggy. The first time we tried it with VRR, the backlight strobing continued to function as low as 10Hz, but below 55Hz, it flickers in multiples of the framerate. Unfortunately, the backlight kept fluctuating and it was borderline unusable, as shown in this slow motion video filmed between 54 and 55Hz. Note that even though it's not that noticeable in real life, the slow-motion video is intended to demonstrate the effect, not how it looks in person.

After experiencing this issue, we power cycled the monitor and restarted the PC, and the BFI feature behaved more like the other Gigabyte monitors we've tested. Below 85Hz, the backlight simply stops strobing, and there are no distracting backlight fluctuations.

This isn't noticeable with most content, but if you prefer something that looks a bit better with the PS5, check out the LG 32GQ950-B instead.

Unlike most other Gigabyte M Series monitors, the Gigabyte M32U has two HDMI 2.1 ports, making it a great choice for PS5 and Xbox Series S|X console gamers. Although the Gigabyte M32U supports HDMI 2.1, like most of the other HDMI 2.1 monitors we've tested, it's limited to 24Gbps. It requires Display Stream Compression (DSC) 1.2a for anything that requires higher bandwidth, introducing some limits on the supported resolutions depending on the source device. You can read more about the supported resolutions here. This article is from our Gigabyte M28U review, but it's also valid for the M32U. For a monitor that supports the full 48Gbps bandwidth of HDMI 2.1, check out the LG 27GP950-B or the LG 32GQ950-B.

The Gigabyte M32U has a few additional productivity and gaming features. It also supports Picture-in-Picture or Picture-by-Picture, allowing you to display two sources at once, but this feature isn't available in HDR or if FreeSync is enabled. Some of the other features include:

  • Virtual Crosshair: There are four virtual crosshairs to choose from. Unlike software virtual crosshairs, these can't be detected by your games.
  • Frame Counter: Displays the current number of frames per second received from the source.
  • Black Equalizer: Adjusts gamma to make it easier to spot other players/enemies in shadows.
  • KVM: The main feature of Gigabyte's M Series monitors, the KVM button at the back of the monitor allows you to quickly switch from controlling one device to another, with just one keyboard and mouse, by connecting them to the back of the monitor instead of your PC.
  • Dashboard: This feature allows you to display vital statistics from your computer, including CPU and GPU temps, fan speeds, memory usage, etc.
