Okay, maybe this is the right forum..
I'm working on an embedded application (running on an ETX-P3 board from Jumptec) which uses an ATI Rage Mobility graphics processor. I'd like to be able to change the TV out settings from my application without having to bring up the display properties dialog (contrast, size etc).
I've tried capturing the registry with the TV out set in various modes and writing over the registry with these settings. After a reboot the driver is reset and I get my new TV out settings. Unfortunately I will have write filtering enabled in the final product so I will lose my changes on reboot.
Is there some way to reset the driver to accept new TV settings in the registry without rebooting or some other kind of API interface to the driver I could use? ATI won't give me any info.
My OS is NT4 (embedded) and I'm stuck.
Any help or pointers in the right direction really appreciated,
