Today I got an answer by Gigabyte, not quite the answer I had hoped for:
Dear Erik ,
AMD Radeon R9 390 only can reach [email protected] due to HDMI version 1.4a.
Only HDMI 2.0 can reach [email protected] via HDMI port. On the other hand, the display devices should be support HDMI 2.0 as well.
I emailed them back:
Perhaps I was unclear in my formulation, but I am quite sure you missed my point unfortunately. I will retry:
I was and am aware of the technicical limitations of HDMI 1.4a which is located on my R390 card (this is 4k 30Hz). So far so good.
I am also aware HDMI 2.0 is needed for 4k 60Hz.
This is exactly the reason I bought a CLUB3D CAC-1070 adapter (please familiarise yourself with this adapter before continuing: http://www.club-3d.com/index.php/products/reader.en/product/displayport-12-to-hdmi-20-uhd-active-adapter.html).
It converts the Displayport 1.2 output to a HDMI 2.0 output.
My device chain setup is as follows:
Computer>Gigabyte AMD R390 > displayport 1.2 > CAC-1070 > HDMI 2.0 > HDMI 2.0 cable > HDMI 2.0 input on UHD TV Samsung JU6650.
Superfluously, I have not connected to the HDMI1.4a port, but to the Displayport.
Within this device chain I have exchanged all devices in order to isolate the problem:
This leads me to the conclusion it cannot be another device than the Gigabyte R390.
Please advice on how to proceed or what support I can count on from Gigabyte. Can you recreate/recognise the problem? If so can you provide firmware update if it is software related or exchange my GPU for an identical one to rule out hardware related issues?
I hope I have more clearly described the issue at hand.
I am looking forward to a workable answer.
ps. please attend to the thread on the CLUB3d forum where I have posted pictures of the tests I described here.
