can somebody tell me specs of Displayport with the different Revisions like 1.1, 1.1a, 1.2, 1.2a? I need to know supportet resolutions and refresh rate of each Revision.
I haven't found what I need, only posts in other forums and everyone said something different there.

I think the reason you are having trouble is because the spec doesn't delineate resolutions and refresh rates, just the total bandwidth.
You can approximate bandwidth by
width * height * refresh_rate * bits_per_pixel * 1.1
1920 * 1080 * 60 * 24 * 1.1 ~= 3.3 Gb/s
Thanks jagabo, that helped me a lot.
For UHD (3840 x 2160):
3840 x 2160 x 60 x 24 x 1,1 ~= 13,2Gb/s
Do you know the difference between 1.2 and 1.2a?
I read a review of a 4K TV (should be called UHD, 4K is 4096x2304) and they talked about Displayport 1.2a.
