Gigabyte M28U Review
Gigabyte M28U 28-inch 4K IPS gaming monitor with 144Hz refresh rate, 1ms MPRT response time, HDMI 2.1, built-in KVM switch and 65W USB-C power delivery.
The M28U carved out a specific niche at launch: a 28-inch 4K panel size that's slightly larger than the common 27-inch class without stepping up to 32 inches, paired with full HDMI 2.1 bandwidth for console gaming at 4K/120. Gigabyte's built-in KVM switch also makes it easy to control two source machines with one keyboard and mouse.
Why It Still Holds Up
HDMI 2.1 with full 48Gbps bandwidth means current-generation consoles can run native 4K at 120Hz with VRR, something not every 4K gaming monitor guarantees. The built-in KVM switch and USB-C hub make it a genuinely useful hub for dual PC/console or PC/laptop setups.
Where It Falls Short
144Hz at native 4K needs a powerful GPU to actually sustain, and DisplayHDR 400 remains an entry-level HDR tier without real local dimming. The 28-inch size is also an unusual middle ground that some buyers may find odd compared to standard 27 or 32-inch options.
Comparison to Alternatives
Against the Dell G3223Q, the M28U offers a built-in KVM switch that Dell's model lacks, though Dell counters with a higher HDR600 certification and local dimming. Compared to the Gigabyte M32U, the M28U is smaller and slightly cheaper, appealing to buyers with less desk space.
