Cannot boot computer when DP is connected. Can only boot with HDMI.

HP Recommended
HP Desktop PC - 870-244
Microsoft Windows 10 (64-bit)

I recently switched from a 4k tv using HDMI to an AOC 49" monitor using display port. When I first booted up with the new monitor with DP, no issues. Switched the display to 5120x1440 @ 120hz, played some CoD Warzone, everything was fine. When I turned my computer back on a few hours later, I got 3 long beeps and 3 short beeps and it would not boot. Upon researching the code, I removed my GTX 1070 and made sure it was seated correctly, rebooted and same issue. Made sure my ram was seated correctly, same issue. I tried using all DP ports on PC and monitor with no luck. I decided to plug in the HDMI cable and my PC booted with no issues. While booted, I can switch from HDMI to DP and it works perfectly fine, just wont let me boot up with the DP connected.

 

Thinking it might be a resolution issue, I lowered my DP resolution to 2560x1440 and tried to reboot, same issue. I am at a loss and am not sure what to do at this point. Anybody have any ideas?
