Our Verdict
LG 27GP850-B/27GP83B-B
Gigabyte M27Q X
The Gigabyte M27Q X and the LG 27GP850-B/27GP83B-B are pretty similar overall. The Gigabyte has a higher native refresh rate, but this doesn't really translate to better motion handling, as the LG looks a bit better overall, especially when gaming on a console below the monitor's max refresh rate. The Gigabyte has better connectivity and more features, with high bandwidth USB-C and a built-in keyboard, video, and mouse switch.
