Hi guys,

I have a Dell 23" monitor that i have been using on my desktop PC, i recently tried to connect my old TV with HDMI to it with HDMI to HDMI cable as a dual monitor set up or just to use as my default screen when watching movies.

When I plug in my Dell monitor all works fine, the moment I plug in the HDMI into the TV as well my PC screen turns off and the TV stays on but with no picture or display.

It did work for a moment but when I tried to change the resolution for the TV in my windows display settings this happened. It almost looks like it is picking up my TV as my default display now but it is not showing anything.

Is there a way to revert these settings or make a change?
My TV is not picked up in my display settings when i turn it off?
