My system: 


OS: Windows 8.1


GPU: Sapphire RX480 8gb


RAM: 8gb ddr3 


CPU: 4690k @ 4.2ghz


Ok so I have my monitor and TV hooked up to my GPU. The monitor to DVI port and TV to hdmi. Today I want to watch some tv so I turned off my monitor as I have done many many times. Then when I went back to use my monitor I go to turn it on and it says no signal. I was confused so I restarted my PC. Still no signal. The TV however worked fine.


So then I went into troubleshooting mode. First I unplugged the TV from the GPU.. then for the monitor I tried a different DVI cable, tried two HDMI cables, updated graphics card driver, updated windows and tried plugging it in to every port on the GPU. Still no signal. The Monitor powers  up but just says no signal.


So I suspect my monitor is broken but is there a way to tell for sure in BIOS or device management or something? Any help is much appreciated.

did you unplug your power from the monitor?  sometime you just let the standby power supply to drain to zero volts so if the board is (lack of better word) confused.  so unplug it and let it sit a minute then plug it in and try it again.  same with pc unplug power and then try turning it on (no cord attached) then plug it back in.  hard reboots will sometimes fix some strange issues.

THANK YOU for your reply dude. i posted on 3 different forums and got nothing.
