That's what it's for. When you make a change and can't figure a way back.
Using the Windows dual display feature on my Lenovo laptop, i setup a 24inch AOC monitor as the only display; the laptop built in display is switched off.
Everything worked perfectly until i changed the resolution on the external monitor to a very high setting and received the error, input not supported.
Now i cant reset it back.
Solutions I've tried.
- Windows restart (same error)
- rebooting in Safe mode (if i leave the monitor plugged up to the laptop i get the same error - input not support - If i unplug the monitor the laptop built in display works perfectly but i am unable to adjust the external monitor settings. As soon as i plug the monitor back in, the error reappears.
How can i adjust the external monitor resolution?
Is there a back end where i can reset the dual display settings?
I'm not IT savvy enough to fix this. Please offer suggestions if you have any.
Thank you
