Monitor will not display on DP, only on HDMI.

I have a dual monitor setup. My primary is an AOC 2460G4, which requires DP to display 1080p at 144Hz. My secondary is an Asus panel. I use HDMI on this one, typically. This morning, however, I was signing into Windows, and both my monitors stopped displaying, and said "No signal." I restarted, and only my secondary monitor using HDMI would display anything, while my primary continued to say "No signal." I switched to HDMI, and now it works, albeit in 60Hz. Device manager seems to recognize something is plugged in when I use DP, but says it is a generic panel. Radeon settings does the same. Windows display settings shows two monitors, but one of them is locked at a resolution of 640x480. Any help is appreciated, this is a very confusing problem.

Edit: Wow, do I feel dumb. The oldest trick in the book worked: Unplug and plug it back in. The power cable, that is. I'll leave this post up for anyone else who has this issue.

System specs are needed: e.g., OS, motherboard, CPU, GPU, PSU, Drive(s) ?
