But the display does not change automatically. I must go to the control panel --> Appearance and click OK on this window in order to change the contrast. Does somebody know how to set this key ?
You can put your Registry Statement in the ADSLOAD.REG file, and update you system with it. This way when the system boot up it will use your new setting.
I made a double check by verifying in the register, after the reset, the registry key have changed to "Current"="High Contrast Black" but the display doesn't take effect !
The shell on some older ADS platforms like the Bitsy does not set the color scheme at startup. You can manually do it with an application run from the Startup folder or from ADSLOAD.EXE using our SetColorScheme sample application.
