Keep in mind that a displayport 1.2 can only do 720p120 or 1080p60 or
1080p24. The throughput is too low for 1080p120. You will need a card
with *DVI-D* or *displayport 1.4a* (and in the latter case, a very
expensive displayport to active DVI-D converter to connect the
monitor). HD7770 cards are often equipped with a displayport 1.2
and/or DVI-I....
Thanks for all the info, but I think this one paragraph is a bit garbled.
DisplayPort 1.2 is the best available for throughput, with a bandwidth
of 17.28 Gbps. It can handle 1920x1080 @120 Hz with ease.
It is HDMI 1.4a which is limited.
"HDMI 1.4 requires that 3D displays support the frame packing 3D format
at either 720p50 and 1080p24 or 720p60 and 1080p24"
