This is already included:

And it's confusing the heck out of people ever since someone attempted  
to estimate the "color resolution". It is extremely misleading. The  
actual frame-buffer resolution never changes, it is always 1200x900  
pixels at 16 bit depth, and that's what matters to developers.
