Our Verdict
Gigabyte M28U
Dell G3223Q
The Gigabyte M28U and the Dell G3223Q are very similar monitors, with the big difference being that the Dell has a larger screen. Besides that, they each have a 4k resolution with a 144Hz refresh rate, VRR support, and HDMI 2.1 bandwidth, and you won't have issues playing games from consoles on them. The Dell displays a wider HDR color gamut, but it has worse tone mapping anyways, so colors in HDR look better on the Gigabyte. They each have smooth motion handling, but the Gigabyte has a backlight strobing feature, which the Dell doesn't have.
