How can we minimize the overhead of the screen when it is not used?
I'm not talking about a headless device, but a device of witch the screen will be used about 10% of the time.
Thanx,

Interesting question, Paul. Will the screen be used in 10% of the devices you ship, or 10% of the time for each system? I'll give answers for both conditions.
If you have some systems that need a display, and others that don't, you could create a headless display configuration as described in this topic.
If you want to turn the display driver on and off, you could change the LaunchCEShell and NoLCDPanel registry keys programmatically, then restart the system; you would have to delete those keys from the ADSLOAD.REG key so its settings wouldn't override the ones you created. Note that except for products like the Bitsy Plus, you wouldn't have any onboard controls to cut off power to the display, so there might still be a power cost in your system.
For most displays to date, our customers haven't see a significant enough performance hit to disable the display driver on headless systems, but we're curious about what works for your application. Let us know!
