Weird the datasheet mentions a maximum resolution of ;
- Supports flat panels up to 2048x1536 @ 60 Hz or digital CRT/HDTV at
1920x1080 @ 85 Hz

Is the some list somewhere with what the Intel Graphic chips can and can
not do ? Like maximum 2D/3D/video-overlay resolution, maximum
framebuffer size, etc. ?

Tom thanks for the info/help.
