Review Summary

Rated 3 out of 5

Awesome but not very friendly with older GPU's

This monitor has good color, refresh rate, the resolution is clean, its aesthetically pleasing, it has multiple ports, the toggling for the settings is easy to manage, the only down side is the terrible signal handshake between my AMD RX 6900 XT and this monitor. This is the only reason I'm giving 3 stars. I hope there is an update in the future that may fix this for others. (Also I know my GPU is dated as well).
