Isn't HDMI just DVI with SPDF and cumbersome DRM in one wire? Because 
any DVI cable run longer than X [1] will fall back to analogue, does 
HDMI have the same facility?

[1] X is a function of the quality of the DVI chip in the output source, 
[2] the cable length / quality and the quality of the DVI chip in the 
display, so your longest possible DVI run changes with any of the above 
variables along with a mysterious force called e-Qi (pronounced like 
itchy but with an e) which measures your ability / luck with all things 
electronic, remember that day when your computers kept crashing and you 
couldn't figure out what was wrong and then the next day they just 
worked, that was your e-Qi my friend.

[2] NVIDIA's on-chip DVI sucks according to Tomshardware however 
manufactures can use a third party DVI chip but how do you tell before 
you by?
