Need help?
Do you have a question about the P166HQL and is the answer not in the manual?
Questions and answers
My PC monitor only displays the small orange square on the bottom right corner of the screen instead of blue, and the screen doesn't display the desktop. What should I do?
If your Acer P166HQL monitor shows a small orange square in the bottom right corner instead of the desktop, it is likely showing the monitor’s on-screen display (OSD) menu, not related to the computer or operating system. This can happen if a button on the monitor is stuck, especially the eColor Management (e) button.
To fix it:
1. Check if any monitor buttons are stuck and gently press each one to ensure they are not jammed.
2. Try pressing the “Auto Config” button to reset the display.
3. Press the “Exit” button to close the OSD menu.
If the issue continues, inspect the monitor buttons for damage or consider a hardware issue with the monitor.
