Dave, is there a limitation to the resolution that one single DP port can push? I can't help but believe that at some point in the future, a very large, wrap around panel is going to emerge, and we'll look back at multi-display systems and chuckle. Will DP be able to handle this kind of resolution with just one port?
The math is pretty straightforward (using DP1.1's 8.64Gb/s data rate):
[list][*]Assuming 8bit per sub-pixel for RGB (24b/p), (8.64Gb/s) / (24b/p) = 360Mp/s[/*:m]
[*]Assuming 60Hz (a typical panel refresh rate), (360Mp/s) / (60/s) = 6Mp/frame[/*:m][/list:u]
Assuming a 16:9 aspect ratio that works out to something on the order of 3264H 1836V. You can play around and figure out other resolutions and refresh rates. DP1.1 won't drive an IBM T221 DG5 at the 48Hz refresh rate.
This is completely theoretical and doesn't deal with instantaneous pixel rates, buffering, blanking periods, etc. all the stuff associated with refreshing a display, thus the usable resolution in today's displays is less than theoretical. In theory (again) a DP monitor could be designed to use virtually all of the bits...
DP1.2 will blow all this away since it doubles the data rate.
If anyone knows of a good wrap-around display, I'd like to hear about.
Meanwhile for interesting stuff take a look at
