--- Comment #9 from wiak@nwgat.net ---
Hey i got the exact same issue with a Samsung HU7505 4k60 television using
amdgpu on xubuntu 16.04.1/16.10, amdgpu-pro-16.50-362463 drivers work in 4k60
until the display is turned off and then it gives "mode not supported"
both the bios and the edid from the display while on crimson 16.12

amd-staging-4.7 kernel, made no difference (git pull today)
ubuntu 4.10 from kernel.ubuntu.com/~kernel-ppa/mainline/v4.10-rc2/
might also be related to black screen on 4k60 issue i have on windows
