I’m not sure which update caused this issue (probably the NVIDIA drivers or Linux kernel, but I can’t be sure), and am wondering if anyone else with an NVIDIA card has similar issues with the same or different monitor, as well as how it could be fixed. I am using an NVIDIA GTX 1050 Ti Mobile with the proprietary NVIDIA drivers. However, the monitor can display anything below that setting, both for resolution or refresh rate, including 1080p60, 1050p75, 900p75, and so on. Though, the screen resolution still changes, so I can move my mouse over and interact with windows unseen to me. However, after a recent update (specifically one I applied on May 14th), my monitor now only displays “Input Not Supported” when I set it to display 1080p75. When I first switched to Linux (first Manjaro, and now Endeavour OS, both with KDE), I was able to use the 1080p75 setting on my monitor with no inherent issues. Its maximum supported resolution is 1080p at 75 Hz. I have been using the Acer SB220Q monitor for a couple years now as an additional display for my HP Pavilion gaming laptop.
