LG UltraGear 27GR93U vs Gigabyte M27U
Both panels land at 68 pixels per degree from a desk distance, so sharpness is not the deciding factor here — the table below is where they actually separate.

68ppd · retina-classAccepts an HDR signal~$500
Two HDMI 2.1 inputs are what separates this one from the rest of LG's 27-inch 4K line, and they are the reason it keeps turning up in console threads: a PS5 or a Series X drives it at 4K120 without compression or a fallback mode.
Best for: One desk shared by a PC and a current console, without a bandwidth compromise on either

Gigabyte
Gigabyte M27U
68ppd · retina-classReal HDR~$530
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

LG UltraGear 27GR93U: what it gives up
- DisplayHDR 400 with an edge-lit backlight and no dimming zones — the HDR mode makes the picture dimmer and flatter, not better
- 1000:1 static contrast means blacks are grey in a dark room, which is the whole reason people cross-shop this against an OLED
- IPS glow in the corners on dark content is the usual lottery and LG does not screen for it
- No USB-C, so a laptop needs a separate dock
- Speakers are absent entirely; the headphone jack is the only audio path
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
