Here's an easy one.  My monitor claims it can do 1280x960 at 75Hz, but it looks 
like crap, the image shakes.  Likewise I have a couple of cards that claim 
really good refresh rates, but that have noticable fringing on high-contrast 
transitions when the refresh rate is too high.  I've even seen cases where 
monitors will refuse to sync at resolution/refresh combos they claim to 
support.

Hardware lies.  Full stop.  And if you think you can work around these cases 
from DDC probe data I've got some oceanfront property in Nebraska to sell 
you.

I'm not arguing against simplified mode selection for the user.  That's a 
noble goal.  It's also a UI issue, and therefore belongs high above the EGL 
layer.  EGL is a mechanism layer, not the policy layer.
