Hello. I own an old monitor (LG W2243T), 1920x1080 @ 60hz. I tend to play FPS games, like csgo and now Fortnite. The thing is, I formatted my PC and now it wont let me create custom resolutions with a higher refresh rate. I played on 1440x900 @ 75hz with no problem, now, when I try to switch to those settings, my monitor gives me an alert message: "Out of signal 83 khz / 75khz", or something like that. Is it a driver problem? Dont know what couldve changed after I reinstalled windows. I am running out of options, I can list pc specs, etc, if needed.
