Hi, Thanks for writing. I know how frustrating it is when your PC keeps running even though the screen goes blank.
Since you can't see anything on the screen, here are some easy ways to change the settings without seeing the screen:
- Start Windows in Safe Mode (without seeing):
- If you hold down the power button for 10 seconds, your PC will turn off.
- Power it on, then shut it down by force after a few seconds.
- Do this three more times.
- Hit Enter, press the down arrow three times, and then press Enter again on the fourth start.
- Wait a few minutes for Safe Mode to load; this mode only uses the most basic settings for the screen.
- Switch to a different screen or TV:
- Use HDMI or DisplayPort to connect your PC to another screen.
- Press the Windows key plus P once, then press Enter. This changes the mode of the screen.
- Press Windows + P and Enter up to four times to switch between modes.
- If Remote Desktop is turned on, use it:
- Start Remote Desktop on a different device and connect to your PC from there.
- Once you're connected, go to Display Settings and change the resolution.
- You can try TeamViewer at https://www.teamviewer.com if Remote Desktop wasn't set up.
