So I have an LG 27UD58 4K monitor and so far it's great. Takes getting used to the physical size. But right now I'm using it at 1920x1080 resolution. Not 1080p though which is also an option. But that looks horrible. But if I try to use it at 2560x1440 which I'd prefer the text isn't as sharp and clear as it is when using it at 1920x1080 or even 3840x2160. I'd never use the full 4K resolution though as everything is very tiny. But I love the 2560x1440 option. Especially using spit screen mode. If I'm using it at 1920x1080 the refresh rate is max 30hz but if I select 2560x1440 then the refresh rate option is greyed out but is says 60Hz (NTSC). Full 4K says 30Hz. Using it at 2560x1440 seems like I'm just using a display that maxes at that resolution. So it's usable but not super clear. The text looks soft. If I try to sharpen it then it looks harsh. Anyone else use their 4K monitor at 2560x1440? Here is my display preferences window. "Default for display" is 1920x1080.
