Basically the title. Been using DisplayPort since I got this new monitor. Yesterday I woke my computer from sleep, and the display was at as wonky resolution so I hit "Restart" from within the Windows 10 lockscreen. After that, it wouldn't turn on - I'd get just a "No Signal" thing on the monitor. It took some fiddling, but I finally got it working via an HDMI cable. When I plug in the DisplayPort cable into the same monitor the HDMI is currently plugged into(ASUS MG248Q - 1080p 144hz), windows detects it as an 800x600 monitor. Switching to the DisplayPort input on the monitor just yields a "No Signal" kind of thing.
I don't have another monitor, cable, or graphics card to test this out with. This is my first 1080p monitor, my first monitor with HDMI, let alone with DP. Got it on Black Friday, started using it Christmas day. Graphics card is an R9 380, Sapphire Nitro variant. Prior to using this monitor, I was using an HDMI to DVI adapter for my old monitor from 2008. Currently using the DisplayPort cable that came with this monitor. Already tried reinstalling my current drivers and installing the latest ones - same results on both.
So, what do you guys think is the problem? Dead card? Broken Cable? Broken Monitor?
Try disconnecting the monitor from power for a minute to reset it.
