How many 2560x1440 monitors can a single AMD 7000 support? e.g. HD 7950? AMD says up to 6 monitors but no word about the max number of monitors at this resolution.
edit: My bad, Shinrai is correct. The question is: How many 2560x1440 monitors can an AMD 7000 drive from a single DP port?
From those documents:
We have this graph:
and it's clear that DP 1.2 can ONLY support 4 1920x1080, 2 2560x1600 monitors and 1 4096x2160 monitor @60Hz and 24 bits per pixel. Can someone please explain why? How they calculated this?
In my understanding 2560x1600x60x24 = 5898240000 bps = 5.898 Gbps Now, 5.898*2 = 11.796 But on the graph is at 13-14 Gbps. What I am missing?
Also, DP supports up to 17.28 Gbps if we take this documentation as correct. On the other hand AMD says their cards support 21.6 Gbps. DP 1.2 max bandwidth is 17.28 Gbps or 21.6 Gbps?
