Re: WINCE : Display driver : VGA to QVGA and QVGA to VGA mode



In Windows CE 6.0 it is possible. Search this NG for "Dynamic Resolution" and you'll find what you need. There is no documentation, but the RageXL driver supports dynamic resolutions. Are you an application developer or do you have access to the BSP (and display driver source)?


Good luck,
