Ok, I use a 50 inch tv for a monitor. My desktop is set to never turn off and never sleep. I just turn the tv off when i'm stepping out or whatever. Lately I turn the tv off and when I turn it back on it says no signal on the tv. I move the mouse around and hit keys on the keyboard but still no signal athough the power light is still on in the desktop. If i hold the power button in until it shuts off then start it back up the tv works so I'm pretty confident its not the tv. Just started doing that and I don't recall doing anything to cause anything.
I use the HDMI 4 port. I set the tv to whatever input I want it on and it stays on that setting until I change it to a different setting. I switched it up to HDMI 2 and just wait to see if it happens again.
