Our Verdict

Gigabyte MO27Q28G

LG 27GX700A-B

The Gigabyte MO27Q28G and the LG 27GX700A-B perform almost identically, as they share the same panel. There are some minor differences in picture quality due to how each manufacturer has tuned the panel, but they are minor overall. For example, the LG over-brightens some images, whereas the Gigabyte slightly crushes midtones and bright highlights in SDR. The Gigabyte unit we bought shows a noticeable red tint on certain shades of gray, but the LG doesn't. It seems to vary between units, though, so not all Gigabytes will have it.
