I have a Dell Aurora 3 running Windows 10 Pro (all updates installed) with a Radeon HD 6900 Series connected via HDMI to a 28" LCD screen.  The Extended Display Identification Data (EDID) information from the screen is corrupted which is not a problem as I have unchecked the "Use Extended Display Identification Data (EDID) or driver defaults” box and set the correct screen resolution to 1920x1200.  However, Windows or the Catalyst Control Centre keeps re-checking the "Use Extended Display Identification Data (EDID) or driver defaults” and hence then sets an incorrect resolution! Does anyone know how do I stop Windows re-checking of the "Use Extended Display Identification Data (EDID) or driver defaults” box please?
