Hello Everyone, i bought an Apple TV 4K yesterday to attach with Samsung SUHD 65JS8500 TV. I have been using till now Apple TV 4th Gen and it worked fine. I am seeing dull colors in ATV 4K compared to ATV 4th Gen, same settings, Dynamic Colors, Chroma Subsampling: 4:2:2..
What i am missing??
HDMI UHD color is turned ON.
Hi Bhavyagoutam,
I have been researching this issue with the KU6300 and while the 11.1 beta improved luminosity, it was only a 10%-15% improvement. I tried 4:2:0 and 4:2:2 chroma and the least improvements were on 4:2:2.
These are my opinions, even those I’ve assumed as fact.
I did some digging and discovered three things:
1) A majority of Samsung TVs out there do not completely support HDR. While they have the option, it’s a lukewarm experience and not worth turning on. Some apps are optimized for hdr, but those are included in their apps store (i.e. the Samsung Netflix app)
1A) The HDMI ports with HDR support only pass some hdr information. It’s part of the issue (Ah... there is data missing in transmission)
1B) Their HDR is propriety and they only partially support HDR10 (hypothesis and needs more research)
2) On my TV and many similar series, the color gamut is not wide enough to truly get full hdr experience (bingo! The dull colors)
3) The contrast and luminosity range is limited (on my model and similar series)
How did I resolve my issue? Well I agree some of it is on Apple. They too have a poor HDR implementaction and deferred the work on HDR by licensing Dolby Vision which is an end to end solution. The tv, device, and media must all support Dolby Vision. This solution is a great idea but it competes with other HDR solutions. Samsung May never adopt it. They have their own standard and have owned the market for a few years so... there is that. I always said “no” to buying one. I broke down on Amazon Days and got one. I was impressed but still feel my tv overrated.
Resolution: I switched to SDR 60hz with a 4:4:4 chroma and did two calibrations. One from rtings site and one ith the THX app on the App Store. The colors aren’t as good with HDR turned on but then again, I would need to be in total darkness and turn up the backlight to full to even see some of the HDR... not enough to justify HDR. At least I have a crisp picture now. Awesome. Guess I’ll wait for the HDR wars to subside

I have the same TV and can’t get the new 4K ATV to connect in 4K - even in SDR mode. Your post gives me some hope (despite the dull color issue) since at least you appear to be getting 4K. I need to test HDMI cables, but otherwise unsure of how to troubleshoot and/or setup TV and ATV. Quite frustrating.
Apple is talking nonsense, there is no such thing as an HDMI 2.0 cable. There are standard, high speed and premium high speed and unless you are watching any 4k at 60 fps, a high speed cable should suffice.
I am seeing the same thing on my Samsung KS8500. A 4k hdr video played via the Infuse app looks way muted compared to the same file played via my OPPO UHD blu-ray player or via Kodi through my nVidia shield. Perhaps this is a Samsung<->ATV situation.
I got my ATV4k yesterday and it was working fine in 4K SDR 60Hz before I changed to chroma 4:4:4 somewhere in the setup. Now I cannot figure out where the chroma setting is. Do I really need to reset to factory settings? Or is there a setting I'm overlooking?
Hi there. Thanks for your insight. I have a 2015 Samsung 4K SUHD JS8500 along with a Apple TV 4K. After experiencing extreme color banding watching the Grand Tour on the Amazon Prime app, I started researching the issue and it led me to here.
Turning UHD Color "Off" on the Samsung picture settings fixes the extreme color banding issue for sure, but will I be able to watch HDR content any more, if I shut the UHD Color option to "Off," I'll lose the ability to stream/watch content in HDR?
No, in fact in the home screen itself, i can tell the colors are dull.
Yes, there is an HDMI 2.0 standard for devices, it doesn't apply to cables.
Cables are “standard”, “high speed” and “premium high speed” and nothing else.
That alone didn’t fix all my issues. See my earlier reply to OP.
Thats´s the problem. I don't have a choice of Chroma in Settings > Video and Audio.
Your assessment seems quite plausible. I’ll do the same here. 👍
Home screen? Change your Appearance setting to Dark theme and see if that’s better.
The chroma setting is removed when a DV setting is selected.
