The catch
Gigabyte M28U 28-inch 4K Gaming Monitor
Height and tilt adjust on the stand, but swivel and pivot do not.
Side by side
Gigabyte M28U vs M32U: M32U makes the same 4K image larger and brings stand swivel
Quick verdict
A smaller desk and denser 4K text favor the M28U. The M32U is for a larger picture or a screen you need to swivel. With 4K, 144Hz and a KVM on both, size and stand movement should decide this.
Before you buy
Why, and what it costs you
The M32U has 26.6% more screen area
On the larger panel, the same 4K desktop comes out 12.5% wider and taller.
Where this comes from
31.5 ÷ 28 = 1.125. Equal 16:9 shapes give 1.125² − 1 = 26.56% more area.
The catch
Gigabyte M32U 32-inch 4K Gaming Monitor
To get PC 4K144 you need a supported DP 1.4 DSC or HDMI path. Over HDMI, 4K144 at 4:4:4 requires DSC and falls back to 4:2:0 without it. PS5/Xbox Series X 4K120 is specified at 4:2:0. The timing table does not confirm 4K144 from every USB-C host. For two-computer KVM use, the desktop must connect by HDMI/DP plus USB-B and the other host by USB-C video/data, with correct KVM Wizard mapping, peripherals attached and KVM ON.

- Why pick it
- Your desk is shallow, or other equipment takes up part of it.
- You sit near the screen and like 4K detail on a smaller panel.
- The catch
- Height and tilt adjust on the stand, but swivel and pivot do not.
Gigabyte M32U 32-inch 4K Gaming Monitor
- Why pick it
- At the same scaling, you want on-screen objects to be larger.
- The screen has to turn toward a second seat.

What this page compares
Desk fit, text size and KVM use set Gigabyte M28U and M32U apart. Both offer 4K at 144Hz, yet their stands take up different amounts of room.

In practice
Differences you will notice
The M32U has 26.6% more screen area
On the larger panel, the same 4K desktop comes out 12.5% wider and taller.
How we worked this out
31.5 ÷ 28 = 1.125. Equal 16:9 shapes give 1.125² − 1 = 26.56% more area.
The compact stand takes 50.7 mm less depth
Compared with the M32U stand, the M28U stand has 20.8% less depth.
How we worked this out
244.3 − 193.6 = 50.7 mm and 50.7 ÷ 244.3 = 20.8%. Cables need room of their own.
A bigger screen is no harder to render
Both request the same 8.29 million pixels per frame when game settings and native resolution match.
How we worked this out
3840 × 2160 = 8,294,400 for either panel. The pixel workload does not grow with physical screen size.
Option A
Gigabyte, M28U-SA
M28U 28-inch 4K Gaming Monitor
The supplied stand is unusually shallow on this smaller 4K gaming screen, which still has a KVM and 144Hz refresh.
- Best for
- 4K gaming on PC and console where desk depth is limited
Facts we checked
- 28-inch IPS panel, 3840 by 2160 at 144Hz
- A built-in KVM and three USB 3.0 downstream ports
- 636.5 mm of chassis width and 193.6 mm of stand depth
- 130 mm of height adjustment
Option B
Gigabyte, M32U-SA
M32U 32-inch 4K Gaming Monitor
Native 4K at 31.5-inch, a paired-input KVM and up to 18W of USB-C power define the Gigabyte M32U-SA. Whether a PC gets 4K144 depends on the input, HDMI 4:4:4 needs DSC, and PS5/Xbox Series X 4K120 is specified at 4:2:0. It has no RJ45, and not every USB-C host is guaranteed 4K144.
- Best for
- 4K gaming on a large screen that isn't OLED
Facts we checked
- 31.5-inch IPS panel with native 3840 by 2160, supporting HDMI or DP 4K144 timing. HDMI 4K144 at 4:4:4 needs DSC, otherwise it uses 4:2:0. USB-C 4K144 is not established for every host.
- A built-in KVM and three USB 3.0 downstream ports
- 715.3 mm of chassis width and 244.3 mm of stand depth
- 130 mm of height adjustment and 30-degree swivel each way
Spec by spec
Where they really differ
| Spec | Gigabyte M28U 28-inch 4K Gaming Monitor | Gigabyte M32U 32-inch 4K Gaming Monitor | In practice |
|---|---|---|---|
| Viewable size | 28 inches | 31.5 inches | Physical size changes on the larger model, but no pixels are added. |
| Resolution and refresh | 3840 × 2160 at 144Hz | 3840 × 2160 at 144Hz | The pixel and refresh budget they start from is the same. |
| Calculated density | About 157 PPI | About 140 PPI | On the M28U, small text is packed more tightly. |
| KVM and USB-C video | Yes | Yes | A keyboard and mouse can be shared across compatible computers with either. |
| Stand depth | 193.6 mm | 244.3 mm | Just over two inches of desk depth is saved with the M28U. |
| Chassis width | 636.5 mm | 715.3 mm | Before buying the larger model, check the extra 78.8 mm. |
| Stand swivel | No | 30 degrees each way | Angling the M32U toward a neighboring chair is easier. |
Trade-offs
What each pick costs you
With Gigabyte M28U 28-inch 4K Gaming Monitor
- USB-C will not stand in for a powerful laptop's charger.
With Gigabyte M32U 32-inch 4K Gaming Monitor
- Because USB-C stops at 18W and there is no RJ45, keep separate laptop power for anything above 18W, along with wired-network equipment. Confirm the USB-C cable package and source support. Make room for the 715.3 mm chassis width and 244.3 mm stand depth, plus cable clearance. We make no claim about measured text comfort, image quality or gaming speed.
Decision guide
How to decide
The M28U suits a smaller desk and denser 4K text, and the M32U suits a larger picture or a screen that has to swivel. Because 4K, 144Hz and a KVM come on both, size and stand movement are what should settle it.
A stand can outweigh four inches of headline size
In reality the diagonals differ by 3.5 inches. A larger picture comes with the M32U, and so does a stand that is 50.7 mm deeper. If that pushes the keyboard toward the edge of a small desk or puts the panel too close, the M28U can be the more comfortable purchase.
The KVM is equipment that gets shared
Sharing peripherals is no reason to buy the larger one, because both models offer the KVM proposition. Look at the connection diagram for each computer. And USB-C video capability alone does not prove that the monitor replaces a high-power laptop charger.
A larger 4K screen doesn't mean more GPU work
The computer is asked for 3840 by 2160 pixels by either monitor. A larger picture can feel more immersive, yet a bigger panel does not raise rendering demand by itself. What makes 144Hz harder to reach is the game, the graphics hardware and the settings you choose.
What this page can’t tell you
- Area comes from the stated viewable diagonals and 16:9 ratio.
- Where the specification consulted did not establish a USB-C charging wattage, none is assumed.
