In my case:
Wednesday - Excitement
Thursday - HDMI 2.0
Friday - HDMI 2.0
The weekend - HDMI 2.0
And it'll still be HDMI 2.0 until I get a solid solution to the problem...
Solution 1: DP - HDMI2.0 adaptor (available soon, probably before Fury).
Solution 2: Hope one of the custom cards has a HDMI 2.0 port (likeness depends on the demand for HDMI 2.0).
At the end of the day, cards like the Fury are a niche market, 4K60 TVs are a very niche market, connecting your PC to your TV is a niche market, so this is like a niche of a niche, AMD probably decided that catering to the 1% of the 1% wasn't worth it with adaptors on the way.
