Suddenly, no input detected from GPU

[Ozz]

Windows 10 home 64bit

Ryzen 5 2600 no OC w/240mm CoolerMaster AIO

32gb Vengeance 3200mhz @2800mhz for stability. 

ASRock B450M Steel Legend (bios 2.50)

ColorPower RX 5700 no oc

EVGA 750BQ

LG 34UM68-P 34-Inch 21:9 UltraWide IPS Monitor

 

 I play games windowed on the right side of the screen, and have YouTube and discord and whatever else open on the left. And all this is connected through display port. 

 

I was watching some YouTube, and things are fine. I get up to go get something to eat, and come back to see what windows stupid power save shut off my monitor. As it does. Which is fine... Wiggle the mouse, monitor turns back on. But this time it didn't. Wiggle the mouse. Nothing.

 

Uodate: found out the issue is GPU not sending signal. No idea why. I don't OC and I don't use 0DB mode, I always keep the fans going. I have no other system to test the GPU, and no spare GPU to swap out and get going again. Any suggestions for what to do next short of buying a new GPU? It's not even a year old. 

 

Unplug and replug in the display port. Nothing.

 

Restart. Nothing, no post either. But I hear windows starting up just fine.

 

Swap to HDMI, nothing.

 

Reboot, nothing, no post screen. I hear windows boot up just fine.

 

Unplugged monitor power and let it sit for a bit, then plugged it back in. Nothing. No post screen, I hear windows just fine. 

 

The monitor is not even a year old, it can't be dead already can it? The buttons on it work, I can access and use the menu. But it gets no signal from my gpu. So I can't get into the bios or anything to troubleshoot. 

 

Where is my issue here? What's my next step to getting my screen to display again?

 

Update, tested a laptop with the monitor, outputs just fine. So.. GPU troubleshooting now please.

Did some testing

Do you have a spare GPU?

 

Display failure isn't something I commonly hear about but issues with GPUs are.

 

Did you try plugging the monitor into any other computer?

Literally tested it as you posted... Yes monitor works fine. No spare GPU.

Can you put the GPU in another computer and see how it behaves? Not sure what's worse for you but if you aren't even getting the BIOS splash screen on screen but you can hear Windows booting it doesn't sound good for your GPU.
