--- Comment #6 from Alex Deucher <agd5f at yahoo.com> ---
You GPU (R7 250) only supports two digital links.  You monitors require 2
digital links per monitor (4 total) when used in DVI mode.  If you attach one
via DVI, it uses both available links so there are no others available for HDMI
or DP.  You can use DP, but you need to use a direct DP connection or an active
DP to DVI convertor since native DP will only require 1 link.  Passive DP
convertors will not work because your displays require 2 links.
