New PC Build and Acer XG270HU goes black screen with blue light after 10-20 minutes each time - DPI

Hello,

Acer 27in 1440p 144hz 1ms refresh TN AMD Freesync monitor - XG270HU

DPI 1.2 connection, cord is one year old and says supports 1440p 144hz (or even 165hz)

(Brand new build below)

ASUS Rog Strix 2080S GPU (DPI 1.4 ports, not 1.2 of monitor)

AMD Ryzen 3700x

2 Corsair Vengeance 3200mhz ddr4 ram

ASUS Rog strix b-450f motherboard

PSU Rosewill 80+ Gold 750W Fully Mod

 

Goes to black screen with blue light after about 20 minutes with DPI connection

 

Things tried:

Reinstalling windows

Turning off gsync

Remounting GPU

Different DPI ports on GPU

Reinstalling Nvidia drivers (Current driver up-to-date for Nvidia 446.14)

With only DPI monitor hooked up (have HDMI monitor hooked up too that never goes dark like the DPI monitor)

HDMI cord on this monitor worked fine

Uninstalling any old drivers I could fine

Did a disk cleanup

Temperatures are fine

Does this even when not in games, just on desktop

Bios seems up to date

Windows 10 up to date

120hz instead of 144hz, seems to last longer before going black

I have not tried a new cord yet but will be ordering today.

I can always go back to the screen by unplugging and re-plugging monitor power.

Thank you for any help, very frustrating after new build.

Does the OSD have an option for sleep? It might be thinking it's hit the timeout... Usually if it's doing things like that without it actually being appropriate we can clear the corrupted setting with a full power reset. Disconnect all cables, press and hold the power button for 30 seconds or so, then wait a few minutes before plugging it all back in.
