Monitor suddenly undetected while playing games

[hoangdong13]

Hi everyone, I'm playing game and my monitor suddenly undetected. I have to restart it and it's back to normal. However, 10 minutes later or when I play games it happens again. I try to change cable, do a clean install but nothing changes 🙁. I don't know what to do please help me guys. Thanks. My spec: cpu: i5 4690k, gpu: gtx 770, psu: 650w, 3tb, ram 16gb.

In windows.

Go to your power settings.
Power options.
Click on change when the computer sleeps.

Set turn off the display to : Never.

Click ok or apply.

Test the system by restarting it once you made the changes in windows.
See if it does it again.

Also.

If the screen went black,or the system froze.

Then the cause can be down to the video driver terminating due to the Gpu on the card getting to hot.
So you should monitor the working temperature of the card when gaming on it.

The card if it has been in the system for some time may need a clean from heavy dust build up if you find the Gpu temps very high.
