Earlier today everything was working fine, turned off my computer for a few hours and now my main monitor is a black screen (has input, it's just blank). I have one monitor HDMI'd into my GPU and the other into onboard graphics as I have for years. My current main monitor is relatively new but has been working fine up until the latter half of today. At first I assumed the issue was my GPU (as that's what the main monitor is plugged into) so tried some troubleshooting there (reseating GPU, reinstalling drivers, etc) before simply trying swapping the HDMI cables so that my second monitor was plugged into the GPU output and the main monitor into the mobo output and the GPU is outputting no problem to my second monitor. I know the obvious answer here is an issue with the main monitor itself, but why would I still get input (but black screen) and my PC have no issues detecting the monitor? I'm hoping there are solutions other than "the monitor is just now somehow dead but only kinda dead". Any help would be appreciated. If it helps the monitor is a Westinghouse WC27PX9019. I have tried unplugging power to the monitor as well as have tried both HDMI ports on the monitor itself.
