I have 2 displays , one is 1920x1080 and the other one is 1240x1024 ( If I remember correctly ,definitely 4:3 though ) .
I use a vga to hdmi converter . My big monitor is displaying perfectly fine , when I try to swap the cables ( disconnect the big monitor and connect the small one ) I get the input not supported message floating, I also dropped the resolution to 800x600 before doing the whole procedure . During boot the display works perfectly fine .So I assume there is no problem with the converter or the gpu . My graphics card is NVDIA GTX 1050ti and I use windows 10 . The small display is acer AL1715 (sorry for the information overload , but I'm fairly new and don't know what's useful info and what's not )
I am going to purchase a second converter , so I was wondering if there is a possibility something might be faulty or that the display is not supported by windows.
Edit : I also tried to use a vga to dvi-d adapter but apparently that's a bad idea. Windows doesn't recognize it on the device manager -> Monitors
