Incorrect color display could result from improper color settings or a loose RGB cable. To rectify this, navigate to 'DISPLAY SETTINGS' > 'COLOR' and adjust the colors to your preference.

If the issue remains, ensure that your RGB cable is securely connected. If the problem persists, consult TechTronics' customer support or replace the cable, as it might be faulty.
