Q: My system doesn't have a display. Can I turn off the display driver to improve overall system performance?
Yes. The display driver can consume as much as 30% of the StrongARM bus bandwidth (8bpp VGA at 45 Hz consumes around 15%). If your final application won't use a display, you can recover that bandwidth for your application by disabling the display driver. The registry key to do this is:
[HKEY_LOCAL_MACHINE\Drivers\Display]Note: As of February 2002, this key is not yet supported on all platforms.
"NoLCDPanel"=dword:1 ; 0=system uses display, [1=system is headless]
You can also reduce operating system overhead for drawing the desktop by disabling the shell (select the product key that matches your platform):
"LaunchCEShell"=dword:0 ; [1=show desktop], 0=suppress desktop
