yep, i would think that it would apply to the HD200x. i'm not using a scart lead. the scart adapter fits into the back of the source which is connected to a vga lead which in turn fits in the hd20 vga port. the adapter working with other sources indicates that it has the pins necessary for RGB. the number for optoma is: 01923 691 800 - press 1 for service. optoma service direct line: 01923 691 865.
