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 monitor for most uses. It's great for office use or media creation, as the large, high-resolution screen is great for multitasking, and it has superb text clarity. It's an excellent gaming monitor with outstanding low input lag and an incredible response time. It's also great for watching videos, but not in a dark room, as it has low contrast and a terrible local dimming feature.
The Gigabyte M32U is a great monitor for office users. The large, high-resolution screen delivers superb text clarity, and it's great for multitasking. It has wide viewing angles, excellent gray uniformity, and okay ergonomics. It also has very good peak brightness in SDR and decent reflection handling, so glare shouldn't be an issue. Finally, it has a few extra productivity features, including a built-in keyboard video and mouse switch (KVM), so you can control two devices with a single keyboard and mouse.
The Gigabyte M32U is an excellent gaming monitor, especially for Xbox Series S|X or Sony PS5 gamers. It has outstanding low input lag, resulting in a very responsive gaming experience. It also has an incredible response time, so there's very little blur behind fast-moving objects. It supports FreeSync variable refresh rate technology (VRR), and although it's not officially supported, it also works with NVIDIA's G-SYNC Compatible feature.
The Gigabyte M32U is an impressive choice for watching videos, as long as you're not in a dark room. The large, high-resolution screen delivers an immersive movie-watching experience, and the wide viewing angles are great for sharing your screen with someone else. It has decent reflection handling and very good peak brightness in SDR, so glare shouldn't be an issue, but it has low contrast and a terrible local dimming feature, so it's not a good choice for a dark room.
The Gigabyte M32U is a great monitor for media creators. The large, high-resolution screen makes it easier to see more of your workflow at once, and it delivers superb text clarity. It also has wide viewing angles and okay ergonomics, so you can easily share your screen with someone else. It has fantastic gradient handling and excellent gray uniformity, so you don't have to worry about banding. Finally, it has an outstanding SDR color gamut, including great coverage of the Adobe RGB color space.
The Gigabyte M32U is a good monitor for gaming in HDR, but mainly due to its excellent gaming performance. It has an incredible response time, outstanding low input lag, and a great selection of additional gaming features, including FreeSync support. Unfortunately, its HDR performance is limited, as it has a low contrast ratio, just alright peak brightness in HDR, and a terrible local dimming feature. It has fantastic gradient handling, alright peak brightness in HDR, and it can display a wide color gamut.
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.
The flat stand supports the monitor well but takes up a bit of space. There's a bit of wobble, but it's not too bad.
The Gigabyte M32U has okay 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.
The Gigabyte M32U has thin borders on three sides. The gap between the bezels and screen is hardly noticeable.
The stand leans back a bit, so the distance from the viewer to the screen varies a bit depending on what the height is set to.
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.
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.
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 very good peak brightness in SDR. There's some variation in peak brightness with different scenes, but it's not too noticeable. Very small highlights are dimmed a bit, but with regular content, it's not noticeable. It's brighter than the Gigabyte M28U, but this difference is in line with Gigabyte's advertising.
These measurements were taken after calibration, in the 'Custom 1' Picture Mode, with the backlight at max and local dimming enabled. The peak brightness can change depending on which mode you're using.
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.
These measurements were taken before calibration, with HDR enabled, with local dimming on.
As expected for an IPS panel, the Gigabyte M32U has a decent horizontal viewing angle. At a wide angle, the image appears washed out, but most people won't notice any issues. This is especially important if you often share your screen with someone sitting beside you or if you like sitting close to the monitor.
The Gigabyte M32U has a very good vertical viewing angle, so the image remains accurate even if you're sharing your screen with someone standing beside you.
The Gigabyte M32U has excellent gray uniformity. There's very little dirty screen effect near the center, which can be distracting when browsing the web or playing games with large areas of similar color. Near-black uniformity is much better, so dark scenes look great, with no noticeable uniformity issues. This can vary between individual units, but gray uniformity is rarely an issue with modern monitors.
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. Note that black uniformity can vary between individual units.
The Gigabyte M32U we tested has great 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 our target temperature. 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'.
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.
You can download our ICC profile calibration here. It's provided for reference only and shouldn't be used, as the calibration values vary per individual unit due to manufacturing tolerances, even for the same model.
The Gigabyte M32U has an outstanding SDR color gamut. 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 outstanding SDR color volume, thanks to the outstanding SDR color gamut. Like most IPS monitors, it can't display dark saturated colors very well due to its low contrast ratio, but this isn't that noticeable unless you're in a very dark room.
The Gigabyte M32U has a decent HDR color gamut. It has great coverage of the DCI P3 color space used by most current HDR content. Coverage of the wider Rec. 2020 color space is mediocre, and it can barely display a wide color gamut.
Note: The DCI P3 coverage is a bit lower than the advertised 90% coverage. It's normal and is due to the way we measure DCI P3. We measure DCI P3 by sending a Rec. 2020 signal, but unlike most reviewers, we limit the colors we're sending to the DCI P3 primaries. This results in a lower but arguably more accurate measurement.
The Gigabyte M32U has decent HDR color volume. It's limited by its incomplete HDR color gamut, and like with SDR content, it can't display dark saturated colors well due to the low contrast ratio.
There are no signs of temporary image retention on our unit, but this can vary between individual monitors.
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.
There's no noticeable color bleed on our Gigabyte M32U. This can vary between individual units, but it's rarely noticeable.
The Gigabyte M32U has decent reflection handling. The matte finish helps to reduce the intensity of direct reflections, but it's not quite as effective as the Gigabyte M28U.
Thanks to the high pixel density, the Gigabyte M32U has superb text clarity, even in apps that don't support ClearType or if you choose not to run the wizard.
|Overdrive Setting||Response Time Chart||Response Time Tables||Motion Blur Photo|
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.
|Overdrive Setting||Response Time Chart||Response Time Tables||Motion Blur Photo|
The Gigabyte M32U has a remarkable 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 a completely flicker-free backlight, 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.
The BFI feature appears to be 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.
Note that our scoring here is based only on the refresh rates supported by the BFI feature and isn't representative of how well the feature works.
The Gigabyte M32U has a fast refresh rate, great for gamers. It supports FreeSync variable refresh rate technology over both HDMI and DisplayPort, and although it's not officially certified by NVIDIA, it also works well with their G-SYNC Compatible mode.
The maximum refresh rate supported varies depending on the source. 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.
The Gigabyte M32U has outstanding low input lag, resulting in a very responsive gaming experience. We tested this monitor after updating it to firmware F06, which fixes an issue with higher input lag that we experienced with the Gigabyte M28U. The Gigabyte M32U likely has the same issue out of the box, so we highly recommend updating it to the latest firmware for the best experience.
Unfortunately, we can't test the HDR input lag at the maximum refresh rate, as we can only test HDR over HDMI, and the maximum refresh rate of this monitor over HDMI requires an HDMI 2.1 port. Our test equipment is limited to HDMI 2.0, so we can't test HDR input lag over HDMI 2.1 at the moment. We don't expect HDR to make any difference to the input lag.
The Gigabyte M32U has superb screen real estate and a very high native resolution, resulting in a high pixel density and superb text clarity. It's also an excellent choice for multitasking.
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. There's also one USB-C port; it supports a few advanced USB-C features, including DisplayPort Alt Mode, 15W fast charging for supported devices. The USB-C port allows you to use the monitor as a KVM switch (keyboard, video, and mouse).
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.
Although it's not currently part of our testing, we also checked for Sony PS5 and Xbox Series S|X compatibility with the M32U, given that this monitor is advertised for console gaming. It's compatible with most features of all three consoles, but it doesn't support Dolby Vision. Because it requires DSC 1.2a and is limited to 24Gbps over HDMI 2.1, the PS5 only works at 4k @ 120Hz with 4:2:0 chroma subsampling since the PS5 doesn't currently support DSC.
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:
You can control the OSD using the joystick button at the back of the monitor, similar to most LG monitors. There's also a dedicated button for the KVM switch.
We tested the 32 inch Gigabyte M32U, part of Gigabyte's M Series gaming monitors, designed with productivity and gaming in mind. All feature a built-in KVM (keyboard, video, & mouse) switch. It's also available in a 28 inch size, which we've also tested. It's a bit different from the other M series monitors, as it's one of the only ones with a 4k screen and HDMI 2.1 support.

If you come across a different type of panel or your Gigabyte M32U doesn't correspond to our review, let us know, and we'll update the review. Note that some tests, like gray uniformity, may vary between individual units.
Our unit was manufactured in June 2021; you can see the label here.
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.
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.
The Gigabyte M32U is a bit better than the Gigabyte AORUS FI32U. The M32U has much lower input lag with the latest firmware, although this could be a bug with the AORUS that will be fixed later. The AORUS, on the other hand, has better ergonomics and more gaming features, including an active noise cancellation feature for your gaming microphone.

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.
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.
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.
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.
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.
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.
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.
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.
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 also has lower input lag and 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.
