Monitor screen stuck at input not supportedhow do I go back ?
Assuming you have not changed the connection to your monitor (from VGA to DVI signal, for example), or that you have not messed around with the display settings, further below may be the situation. Else, you need to access your LCD menu and choose the other type of input SIGNAL.
It appears your display adapter is set to a different refresh frequency or resolution, either accidentally or due to some power glitch.
If you cannot set the resolution because this message is preventing you from getting to the display settings window, try rebooting your PC in Safe Mode. It'll take a while longer than usual, but when you're finally running, try setting your display adapter to a resolution of 800 x 600 pixels at 60Hz settings. This is available under "Advanced->Adapter->List all modes".
To reboot in safe mode, try pressing the PF8 keys repeatedly after the POST messages disappear just after turning the power on. This only works if this key is enabled to operate from the BIOS settings.
To get to the BIOS setup, Look at the first messages displayed on your screen indicating what key to press. It's usually the Delete or PF2 key, but different BIOS manufacturers use different keys.
Once inside the BIOS setup, find the way to enable the PF8, PF9, PF10, etc keys. Save your settings and reboot.
Now you may try PF8 again to go to Safe Mode.
If your PC is Ok, then you may try setting your monitor to a higher resolution, taking care not to exceed the maximum values, as stated on the user's manual.
