Constant Input Signal Out of Range HP 2011x XP597AA

[C_TO22]

Input Signal Out of Range is always on my screen but my screen is working fine. Is there any way to disable it? Windows is working perfectly, I can see everything, but even after factory resetting the monitor (to 1600x900@60HZ) Input Signal Out of Range bounces around the screen at all times.

Welcome to the HP Support Community.

To resolve this behaviour, either change the refresh rate or change the video adapter settings.

To change the refresh rate:

1. Restart the computer, and while it is restarting, press F8 until the Startup menu appears. Press 3, and then press ENTER to start the computer in Safe mode. 

2. Right-click the desktop, click Properties, and then click Settings. 

3. Click Advanced, click Adapter, and then click Adapter Default from the Refresh Rate list. 

4. Click OK, click OK again, and then click Yes to restart the computer in Normal mode.

You can set the colors and screen area to your preferences under Display Properties.
