Gigabyte M27U vs Gigabyte M27Q X

The Gigabyte M27U is 22 pixels per degree sharper at a desk distance — 68 against 46, 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

Two hundred and forty hertz at 1440p with a KVM for around $400 undercuts the next monitor here that manages all three by more than $200.

Best for: High-refresh 1440p and a KVM on the smallest budget that buys both

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 M27Q X: what it gives up

  • HDR is a badge and little more: 350 nits, 1000:1 and no dimming zones, so SDR is the better place to live
  • HDMI 2.0 with no DSC, so 240 Hz is DisplayPort-only and a console is capped at 1440p120
  • Two revisions ship under one name and the later one covers 94% DCI-P3 rather than 92%, which sellers rarely state
  • Tilt and height only, so squaring it up beside a second monitor means moving the whole stand
