The Gigabyte M32U is a 32-inch 4k mid-range gaming monitor that's bigger than the Gigabyte M27U. It has several gaming-focused features, like HDMI 2.1 bandwidth, a 144Hz refresh rate, and FreeSync and VRR support to reduce screen tearing. It also has several productivity features. You can easily switch between two PCs and use the same keyword and mouse, thanks to the KVM switch. Additionally, it has a USB hub and DisplayPort Alt Mode support with 15W USB-C charging.
Our Verdict
The Gigabyte M32U is a decent PC gaming monitor. It has a 144Hz refresh rate and supports all common VRR formats to reduce screen tearing. It has low input lag for a responsive feel and good motion handling at high refresh rates. However, it's worse with lower refresh rates due to more blur and inverse ghosting. Unfortunately, it has limited picture quality, as it has a terrible local dimming feature, and blacks look gray in dark rooms.

The Gigabyte M32U is great for office use. The high-resolution screen delivers superb text clarity, and its 32-inch size allows you to open multiple windows at the same time. It has decent reflection handling and very good brightness, so it overcomes glare in most environments. It also has good ergonomics and satisfactory viewing angles, so a colleague sees a consistent image from the sides if you're sharing your work. While it has USB-C charging, it doesn't deliver enough power to recharge most laptops while they're in use.

Differences Between Sizes And Variants
We tested the 32-inch Gigabyte M32U, part of Gigabyte's M Series of gaming monitors. The full model code may vary between regions, like the Gigabyte M32U-SA, which is the same monitor. The M32U Arm Edition is nearly identical to the M32U but has an arm that clamps to a desk for mounting, unlike the M32U's desk stand. The results in this review are only valid for the model we tested.
| Model | Size | Native Resolution | Max Refresh Rate | Support Type |
|---|---|---|---|---|
| M32U | 32" | 4k | 144Hz | Desk Stand |
| M32U Arm Edition | 32" | 4k | 144Hz | Arm |
Our unit was manufactured in June 2021; you can see the label here.
Popular Monitor Comparisons
The Gigabyte M32U is a good mid-range 32-inch gaming monitor with added productivity features like a KVM switch, DisplayPort Alt Mode support, and USB-C charging. It's a great choice for work-from-home setups, as the monitor works well for gaming and productivity work. Additionally, thanks to the KVM switch, you can easily switch between two PCs and use the same keyword and mouse. If you're looking for a 32-inch monitor that costs less and you don't need the M32U's productivity features, consider the LG 32GP850-B/32GP83B-B, which delivers similar gaming performance at a considerably lower cost, though it has a lower resolution and doesn't have HDMI 2.1 bandwidth.
For more options, check out our recommendations for the best 32-inch monitors, the best 144Hz monitors, and the best gaming monitors.
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 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 Dell G3223Q and the Gigabyte M32U are both decent 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.
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.
The Gigabyte M32U and the Samsung Odyssey G70D S32DG70 are 32-inch, 4k gaming monitors. The Gigabyte is the better option if you're gaming in a dark room, as it displays deeper, more uniform blacks, though it still looks gray. However, if you're looking to see a wide range of vivid colors or you want to use your monitor like a TV, the Samsung is a better choice.
We buy and test more than 30 monitors each year, all of which we purchase ourselves, without cherry-picked units or samples. We put a lot into each unbiased, straight-to-the-point review, and there's a whole process from purchasing to publishing, involving multiple teams and people. We do more than just use the monitor for a week; we use specialized, custom tools to measure various aspects and deliver objective, data-driven results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance compared to the competition, and whether it's easy to find.
