When is RX 5700 XT and HDMI 2.1 update coming?

I was wondering if it will be possible to get 4K @ 120 Hz and YCbCr444 out of the this GPU. I have the right cable (8K certified 48 Gbps ). But when I set the desktop to 4K 120 HZ, all I get is this:


8 bit, YCbCr420, SDR. If I set the refresh rate all the way to 30 Hz, then it's 12 bit/YCbCr444/HDR.

I've ready many forum posts on different websites saying that the GPU is only capable of HDMI 2.0b. Then there was mention that AMD would release driver/firmware update that would upgrade the HDMI port to 2.1. I don't know how that's even possible, but what happened? Is this no longer ever going to happen?

Do I need to start looking for a GPU capable of getting the full potential of my TV's hardware?

This is impossible we do not have the 2.1 port we have the ages old 2.0 port on our products

Only the later models might have the 2.1 ports mounted, but i admit not look at that as i not really game much

So for me i was already disappointed that they introduced the 5700 cards with that old port.

But on the other hand the card can not really do 4k well, it is not really made todo that.

sure it can run 4k a bit but it has to be not one of the younger games as it would choke in the graphics.

It can run it 1440p but when i tried a few heavy games you already feel and see its limited.

Now the Asrock card i have the Taichi RX 5700 XT is really performing very good and is often scoring above many overclocked ones which i not even have todo. In 3d mark it ends in the highest regions of performance just at factory settings with my 9900 KF which is constant running at differents speeds one moment it does 4.8 ghz the other it goes perfect 5 Ghz.

But always ends between all the overclocked systems in performance never in the standard ones.

Anyway if you really want a card capable to run at these TRUE 4K your probably have to wait till they release a card which really can do that, now i admit i have not looked at the 6900 models of AMD at all so it might be possible that cards can do that.

But its so insane expenssive it is not even worth looking at.
