    Has anyone successfully activated 4:2:2 HDR? I have a 55" Samsung 9000 series with my AppleTV connected via HDMI2. I'm using a HDCP 2.2 compliant cable.

    I finally got it setup but had to put it on a specific hdmi and use a different cable. Both cables were rated for it. Sony xbr75x940e hdmi 3

    I was able to enable it for my Vizio M55-E0, by setting the picture mode to Computer. That’s the only mode that allows 4:2:2 for me. Otherwise it’s 4:2:0.

    I was able to activate it, but had to turn it off. I was getting bad banding on the home screen on orange and red icons. Even tried it using the cable that I use for my UHD player.

    It works on my 55KS8000 but I find that it looks terrible until it’s recieving an actual HDR signal, then it looks great. However my home screen and non-HDR programming do not look good at all. Turning it to 4K SDR makes everything look great. Not sure this is worth it to keep or return until they figure out how to let the TV decide what’s an HDR signal and what’s not.

    Works here with my LG B6. However none of the DV content is playing back as DV. It’s always HDR only. So somthing is borked. It’s not my cables or TV. They can handle the content and I play it back with other sources just fine.

    Exactly!! You will have to manually put it on 4k HDR 60hz when watching HDR movies and switch it to DV 30hz in our case since the lg b6 doesn’t support DV 60hz... that should happen all automatically hope apple will fix this very very soon

    Actually should switch it to DV 24hz, not 30hz.

    Don’t you find that running the HDR signal all the time looks terrible? I find it incredibly dim until it receives an actual HDR Signal. Standard HD/4K doesn’t look good upscaled to artificial HDR

    Did you enable UHD Color?

    I’m not seeing DV anything as an option in ATVs menu. 4K HDR 30hz and 24hz, yes. Both of which I tried but still only getting HDR.

    Enabled it OK from the menu, I have a high speed certified HDMI cable as well, 6ft long. First thing to try is always the cheapest, got a spare cable?

    Not been through the whole menu yet but some options on the video seem to open up others that were not there until something is enabled.

    I enable it to HDR 4:2:2 but my screen either got dimmed or lighter output. The best output for me is the SDR 4:4:4.

    Seems like the consensus is the output is crap until it receives an actual HDR signal which is disappointing. Hopefully they update the system to run in 4K SDR until it receives an HDR signal and then switches itself over.

    Anyone having any issues with directv now? I find that it’s constantly freezing and I have to keep closing the app.

    I am having issue with it. Seems to have problems opening up the previous channel. I get a continuous “blue bar”. Running latest Directv Now app.

    I have the exact same tv and 422 works great. I find the always on hdr to look incredible. Everything is incredibly vivid and sharp. Non 4k content looks way better because of the hdr.

    Like most others, the screen is either too dim or too bright until HRD signal is received but i do like the overall product, makes everything else looks better

    Yup, this is what I’m seeing too.

    I find that the always on hdr makes everything look dim. HDR looks great but the home screen or anything else looks washed out.
