No HDR support yet but it sounds like they are working on it.

Good to know! Thanks. Not sure which mine is I sent my ju7500 to be a bedroom TV where as the ks8000 and js9000 to do the heavy lifting in the living room and computer desk.

No I’m not from club3d.

As far as I know you have to request the firmware and they email it to you.

Your screen has to support 10bit and 12bit color in order for that to be selectable on your graphics cards drivers. Just because it’s 4k UHD doesn’t mean it’s an 8bit or 12bit panel.

UHD standard is only for resolution not color depth. I have a Samsung ju7500 UHD that is only an 8bit screen.. I also have a Samsung js9000 and ks8000 that are both 10bit. LG makes UHD screens that are 12bit panels. On my 10bit screens 10bit is only selectable in the drivers if I lower chroma to 4:2:0 and refresh rate to 30hz because anything higher exceeds HDMI 2.0 standards. The adapter is capable of all of this within the HDMI 2.0 specs. It just doesn’t pass the HDR meta data on through the display port but to be fair it doesn’t actually claim to do this.

I found the table at the bottom but there isn’t anything about HDR in it.  Says it supports RGB, which is a color standard, and various other color formats like 4:2:0, 4:4:4 at different resolutions. All of which have nothing to do with HDR.  I’m I missing it somewhere else on the page?  I literally see nothing about HDR – High Dynamic Range.  Your only going to get 10 or 12bit color at 4:2:0.  Anything above that exceeds the 18gbps bandwidth of HDMI 2.0 which doesn’t have anything to do with the club3D adapter.

Where do you see that it says it supports HDR?  I looked all over the product description of the cac-1070 and don’t see anywhere where it says anything about HDR.

I did the same exact testing with those games. With hdr enabled with the same adapter I didnt the get those lines but the picture was super dark.

Thank you for the open response.

I don’t know anything about Mac’s but doesn’t your drivers for your graphics adapter include some sort of custom resolution ability?  Seems strange that you would have to purchase something to do that.

[Kahless]

Thanks for the reply.  Sounds like I don’t need to worry about the firmware unless I have a problem?

My cable will be fine as I have tested it on a separate Titan X system I have, and it of course has the Hdmi 2.0 port and does 4:4:4 60hz 4k just fine with my cable.  So I would suspect the adapter will work fine with my 390 out of the box then on the Samsung JS9000.
