Ah nuts. I didn't think to check 4:4:4 (I was mainly concerned with 2160p & 60Hz) and the machine has been taken apart. Will try to check sometime next week.

My opinions do not reflect the policies of my company

The TV's set to PC mode and UHD color is enabled on the port (HDMI 1). All I get is a mostly blue screen with a flickering band at the bottom. I can get 30Hz 4:4:4 and RGB through the adapter but I can get those straight from the HDMI port. Heck, I can get 60Hz 4:2:0 through the HDMI port. The only reason to get the adapter is to get 4:4:4 color.

My experience has been similar. But I don't even get a blue screen. The screen doesn't do anything, straight black/blank. I have a UN48JU6500FXZA and my video card is a Quadro K2000.

Here are some suggestions I got from Club 3D support:
  • color depth needs to be 8 bit
  • turn off GPU scaling
  • make sure HDMI cable is capable of at least 18 Gbps
  • there is also a firmware update for the dongle itself, thought you have to have the dongle plugged in to apply it

I have done all but the last and still can't get 4:4:4.

I assume you are referring to this adapter:

UpTab responded to my inquiry and pointed me at a thread from 2014 that hinted people on another forum had success doing a clean install of the Nvidia drivers without the GeForce experience. Of course it had nothing to do with this adapter since it didn't exist in 2014 but I figured it couldn't hurt. I tried that and now I can't get 4k to work through the adapter at any refresh rate. The driver crashes if I hook up the 4k display to the adapter.

I'll let them have a few more tries before I return it. Amazon doesn't have the Accell or Club3D in stock so I've got nothing else to try for now.

As far as I am aware, you are correct. You'd be limited to 8bpc with those settings.

Also, FWIW, the new firmware for Club3D adapter works better for me, allowing additional refresh rates to work. Unfortunately for me, while my TV will take the 4k@60 signal fine it drops frames when it displays it.

The Club3D CAC-1070 adapter indicates that it can only do 4:2:0 color at 3840x2160 at 60hz at 10 bit. I believe the Samsung UN40JU6500FXZA is a 10-bit screen. That may be why you can not get 4:4:4 color. The adapter can do 4:4:4 color at 8 bit.

Please see the spec page for the adapter (I cannot post the link per forum terms).

Here are the tv specs:

Computer inputs on all HDMI:

up to FHD 1920 x 1080 @60 Hz
4K Ultra HD 3840 x 2160 @30 Hz

Video inputs on all HDMI:

up to FHD 1920 x 1080p
@ 24, 25, 30, 50, 60 Hz
up to 4K Ultra HD 3840 x 2160p
@24, 25, 30 Hz

No. You are limited to 30 Hz at 4K Ultra HD 3840 x 2160. You need a HDMI 2.0 or HDMI 2.0a connection on the tv to get to 60 Hz at 4K Ultra HD 3840 x 2160.

HDMI 1.4 supports 4K resolutions, but only at 24 or 30 frames per second. That works fine for movies, but isn’t useful for gaming and many TV broadcasts, which require 50 or 60 fps. Also, HDMI 1.4 limits 4K Ultra HD content to 8-bit color, though it is capable of 10 or 12-bit color. HDMI 2.0 fixes all of that because it can handle up to 18 gigabits per second — more than enough bandwidth to allow for 12-bit color and video up to 60 frames per second.

General AMD HD 7970 partial specs:

DisplayPort 1.2
Max resolution: 4096x2160 per display
Multi-Stream Transport
21.6 Gbps bandwidth
High bit-rate audio
2560x1600p60 Stereoscopic 3D
Quad HD/4k video support

3GHz HDMI 1.4a with Stereoscopic 3D Frame Packing Format, Deep Color, xvYCC wide gamut support, and high bit-rate audio
Max resolution: 4096x3112
1080p60 Stereoscopic 3D
Quad HD/4k video support

Dual-link DVI with HDCP
Max resolution: 2560x1600

VGA
Max resolution: 2048x1536

You didn't list the specific manufacturer and model number of the video card that you have, so I listed the general AMD HD7970 specs above. Not every AMD HD7970 may have these specs. The video card manufacturer can make changes.

If the video card has HDMI connections on it, just try connecting the tv via an HDMI cable. I do not think that the Club3D adapter will give you any better output that that.

Again, with your 4k tv, the maximum refresh rate that you will be able to get at 3840 x 2160 is 30 frames per second (fps). It looks like the Club3D displayport to HDMI 2.0 adapter should allow you to get 3840 x 2160 at 30 frames per second (30 Hz) with the AMD 7970 video card. The HDMI 1.4 connection on the tv is the component that will keep you from getting 3840 x 2160 at 60 frames per second (60 Hz). 30 frames per second will make games appear choppy. I do not think that I could watch 30 frames per second images for very long without getting a headache.

Yes, my understanding is that you are limited to 30 Hz because your 4k tv input is only HDMI 1.4. The Nvidia GTX950 and higher (960, 970, 980, etc.) cards have HDMI 2.0 output which would give you 60 Hz IF your tv had HDMI 2.0 input (BUT IT DOES NOT). You need a different 4k tv that has HDMI 2.0 or displayport 1.2 input to get 60 Hz. There are no AMD video cards that I know of at this time that are available with HDMI 2.0 output. The Nvidia GTX950 and higher (960, 970, 980, etc.) cards have HDMI 2.0 output will probably give better color specs than the Club3D displayport to HDMI 2.0 adapter. I just tried a GTX960 video card with a Samsung JS8500 tv, and I could get 3840 x 2160 @ 60 Hz with chroma 4:4:4 with 10 bit color depth. Per Club3D's specifications, I would NOT be able to get the chroma 4:4:4 with 10 bit color depth with the Club3D displayport to HDMI2.0 adapter (only chroma 4:4:4 with 8 bit color depth).

I would suggest that you return the HD 7970 video card if you can (without losing money), and purchase a Nvidia GTX950 or higher card if you think that you will one day purchase a 4k tv with HDMI 2.0 input. However, Nvidia GTX950 or higher card won't give your current 4k tv a 4k refresh rate any higher than 30Hz (because your tv only has HDMI 1.4 input -- and that is the limiting factor).

The Club3D Displayport 1.2 to HDMI 2.0 UHD (CAC-1070) adapter is supposed to be back in stock at Amazon.com on 3-24-16 . You can order it now, and be first in line to get it shipped out when it arrives at Amazon.

I just received my adapter today from Amazon and it works perfect with my Vizio p65 and LG. It will do 4096 and 3840@60. The new stock are Rev A1-00 with FW7.1E. The older firmware had issues reading EDID from some brands. I had to set the color to 8bit for 4:4:4 on the LG.

What are people using these days, the Club 3D adaptor or UpTab (http://www.uptab.com/minidisplayport...ld-plated.html) or ...? I have a XBRx43c that I would like to achieve 4K @ 60hz 4:4:4.

Please advise!

Hey Everyone,

I was having the same issues as people above. I could only get 4k 30p out of my Samsung 4K tv hooked up to a Mac Pro using the Club3d adapter. I then went into the menu settings on my TV and switched on UHD Colour. Once this was switched on my TV now display 3840 x 2160 at 60p!! Hurray. I almost lost hope...

I can confirm my Club3D DP->HDMI 2.0 active adapter only works at 2160p@50Hz in 8 bpc mode, using my Quadro M2000 and the Samsung KS8000 SUHD (2016 model) TV. I need it to be configured as follows:

- 2160p@50Hz
- YCbCr422 (minimum) color resolution
- 10 bit colordepth

-as I'm a professional video editor and this is the format of footage I'm editing in BlackMagic Design daVinci Resolve NLE (I'm using the Sony FS7 camera and the XAVC codec).

My colleague from another forum claims that he is using the mini-DP version of otherwise the same adapter, and is able to run his similar Samsung SUHD panel with 10-bit color. Could it be that the mini-DP version has full YCbCr422, 10-bpc capability, and the (full)DP->HDMI 2.0 version does not? Very strange...

Best,

Piotr

Hi all! I know 2016's almost over, but any update on this?

I just got two 4k LG 27UD68 monitors, and I want to connect them to my Surface Book at 4k / 60 fps (through the Surface Dock). Surface Dock has two miniDP ports, and the LG 27UD68 monitor has two HDMI ports and one (full) DP. Not sure what to buy. I'm considering DP>miniDP cables/adaptors, or HDMI>miniDP adaptors/cables. Any suggestions what would get me best 4k 60fps picture?
