Desktop won't connect to TV anymore


Jul 2, 2017
My desktop computer was having no trouble connecting to my LG tv this morning. Now though, the tv still recognizes on the input screen that something is plugged into the hdmi slot, but it says there's no signal.

Other devices have worked fine in that slot, the pic has failed to connect to other slots, I've changed hdmi cables, blah blah snore.
HDMI especially when used with a PC is a royal pain.
The order you boot the PC and select the input will affect if and how the PC and TV handshake. If you change inputs after you boot the PC try changing inputs before. Might take 10 seconds for the desktop to show.
