I got a new Tv and planned to use it as a second monitor but when I plug the hdmi in The tv just stays at a black screen, and in my computers resolution settings it only picks up my old monitor.
what resolution is the tv? what resolution is your current monitor? did you try restarting your pc with the tv still on? you verified the hdmi port works and the cable is fine? the tv shows up not at all under multiple monitors in your software?
