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.
