Display Port to HDMI 2.0 Cable

[id6016]

I need a cable that can connect my R9 390 and my 4K TV. My TV only has HDMI 2.0 ports and no display ports and the R9 390 has no HDMI 2.0 ports. I would prefer an amazon link.

Thanks for the suggestion, but i ended up getting this adapter: http://www.uptab.com/displayport-to-hdmi-4kat60hz-adapter-cable-gold-plated.html It states 4k at 60hz, Plus it was only 40$

Any places where I can get a 4K @ 60Hz 4:4:4 chroma subsampling, displayport to hdmi 2.0 in the UK? Struggling to find one currently.

it looks like either will ship in the next week or 2 if you are in the UK. but i have not found a US retailer with them in stock yet.

DO NOT buy the uptab one. it is the same as the allreli brand on amazon (but its only $11 on amazon). its not true hdmi 2.0 so it wont give you 4:4:4 when at 4k 60hz (or so i have read). to be honest i just dont trust uptab, i think they are charging way too much, and they probably just order from amazon themselves.

Great, thank you! Hopefully they'll be available soon; want to be able to use a 4K TV as a monitor before I get my new graphics card.

same here. i bought a 295x2 used on ebay last february, shortly after buying a vizio p652 4k tv. for the most part i still enjoy 4k 30hz for GTA V and 120hz 1080p for Black Ops 3. but i would love to be able to set it to 4k 60hz.

 

[MylesMor]

Do you not have trouble playing at 30Hz?

 

[carlosriosness]

gta v looks fine/enjoyable/playable at 30hz. but i couldnt play call of duty at 30hz. its kinda weird how one game is playable and the other felt too slow/choppy. far cry 4 is also playable at 30hz.

my tv use to accept 1440p at 60hz which was a good middle ground but after a firmware update it no longer accepts that.

black ops 3 has super/dynamic resolution (in game settings). so i set the game to render at near 1440p but it displays at 1080p so i get slightly smoother (less edgy) 1080p gameplay (basically like AA).

Club3d product is only capable of showing 4:2:0 (8bit) 4K@60hz over HDMI 2.0 which you can get that over HDMI 1.4 too (with some graphics chipset+specific driver+specific monitor/TV). 8 bit color is not a problem for gaming - which you can't get enough fps for 2160p so you'll probably go for lower resoultion on gaming and you'll definitely get 16 or 24 bit color at that resolution but 8 bit color on windows desktop or watching movie should be problem. So it's better to get a graphics card (GTX950 or over / R7 370 or over) and use HDMI 2.0 for working on windows desktop.

my tv doesnt do 4:4:4 4k 60hz anyways. (vizio p652) . but i figured i will game at 4k 60hz 4:2:0, but just change my display settings to 4k 30hz when doing desktop work.

Can you confirm the source of your information? As from what I have read on the Amazon listing it specifies the following.

"Color depths on 3840x2160 @60hz, - HDMI: RGB 8/10/12 bpc; YCbCr4:4:4, YCbCr4:2:2 and YCbCr4:2:0 8/10/12 bpc"

Doesn't this mean it can do the 4:4:4 sampling?
