Look its ok but could be soooo much better. the screen quality is very good, havent quite OC it to 240Hz yet. But the biggest issue for me is the the super tight input section at the back. it is so awkward and tight for the inputs to be put in. It also only has 1 USB-C, 1 HDMI and 1 DP which really limits inputs. Running the PS5 on this screen is ok but the monitor's inability to support 21:9 makes it quite uncomfortable. for office and movies and general desktop work - really good. For some gaming if you adjust the view its really good. Just a few small isses stop it from being really good.
