R9 290X with HDMI 2.0???

Since I can't upgrade the whole system now, and really only need it for relatively "light" XAVC-S files - please tell me: have you heard of R9 290X cards which would offer not only Display Port 1.2, but also HDMI 2.0, full 4K resolution? For some reason this is extremely important to me at the moment:

I think you just do this out one of the display ports.

The 290x supports HDMI with deep color, so getting an adapter cable that supports the right standards is important.

Look at the spec page for HDMI support.

Thanks guys - but I should have added that it's going to drive one of those early QHDTVs rather than a QHD monitor, so Display port is not the option.

I read all websites with specs for the R9 output - and while they say about HDMI "Quad HD, deep color" I'm afraid this is just going to be 4k@30 Hz (or 24Hz) only which is not enough for me (DP 1.2. provides full UHD@60 HZ and 30 bit color - 10 bit per channels, I guess). So:

- is the R9 HDMI 2.0 (which also provide full UHD@60Hz)
- or is the HDMI 1.4a, and you suggest using DP 1.2. with one of those DP->HDMI converters which are mixed opinions as far as drinking QHDTVs is concerned?

Thanks,

Piotr

Further study I find that the 290x hdmi may only be v1.4. The active displayport adapter would be a way to go, but it looks like we are waiting on an updated active adapter to be released. DP1.2 has about 20Gb/s, and HDMI2.0 about 18Gb/s, so an active adapter should work. NAB is this time next month, and we could get more releases like that. According to another poster on AVSFORUM, Bizlink demonstrated at CES 2015 a DP1.2 to hdmi2. adapter. My guess is that the 390x will come with all the updated standards as a marketing carrot to buy the latest GPU.
