Gigabyte M27U vs Gigabyte M32U
The Gigabyte M27U is 9 pixels per degree sharper at a desk distance — 68 against 59, and that is the line between sharp and retina-class. Every other published specification for both is in the table, with the rows where they differ tinted.

Gigabyte's habit of fitting a KVM to mid-priced gaming monitors is what separates this from LG's 27GR93U, which is otherwise the same proposition: 27-inch 4K, two HDMI 2.1 ports and an edge-lit IPS panel, with no way to share one keyboard between two machines.
Best for: A 4K gaming desk shared between a PC and a work laptop

Gigabyte M27U: what it gives up
- The USB-C port carries 18 W — enough for a phone, not for a laptop
- HDR reaches roughly the 600 nits it claims, but contrast stays at 1000:1, so bright scenes gain punch and dark ones stay grey
- Measured DCI-P3 coverage lands nearer 91% than the 95% on the spec sheet
- Tilts and raises 130 mm, but the stand neither swivels nor pivots
Gigabyte M32U: what it gives up
- 90% DCI-P3 shows its age against newer panels at the same money
- The stand swivels and raises 130 mm but will not pivot to portrait
- USB-C carries 18 W of data power, not laptop charging
- DisplayHDR 400 over an edge-lit backlight with 16 dimming zones behind 400 nits — the badge, not the capability
