Question Display settings glitch when only 1 of 2 monitors is on.

[shadowkon626]

I have two monitors which i always have set to "duplicate". A TV (monitor 2) and a normal Gaming monitor (monitor 1). Recently, whenever i only turn on "Monitor 1" windows switches to "Extend these displays" and it adds a non existent display to the right side of "display 1". If i go to display settings and click "duplicate these displays" as soon as i click "keep changes" itll instantly revert to "extend these displays". If i only turn on display 2 this is not an issue. Itll only display 1 monitor (display 2) in the display settings. If turn on "display 2" after first turning on "display 1" windows will automatically go back to "Duplicate these displays". if i then turn off display 2 itll revert back to the "extend these displays" issue. It also seems to change to the "display resolution" when the issue occurs. this has only been an issue for about a week or so. Ive had my PC for a few years now.

Ive already upldated my GPU drivers and my CPU drivers and it didnt fix anything. Anytime i think ive fixed the issue itll just end come coming back. The reason this is annoying is because sometimes ill open a program and itll open in the non-existent 2nd display.

any help would be appreciated.

you´ve connected both displays, so windows wants to display on both. You an drag the 1st display to the left or right if you want.
did you try changing video ports? Display 1 in the port where Display 2 is connected to and vise versa.
which GPU and monitors are you using?
try other video cables
update the BIOS of the motherboard
