I own a sony 850C. NEWEST UPDATES for the tv and Xbox. Though the tv is hdr 10 and passed everything in the past. As of the latest update, the tv no longer can handle hdr gaming. This needs to be fixed.

I've actually been trying to solve this problem as well. But since you're the first person I've found who's posted about it, I'd like to try a few things and cross reference your experience with mine if you're up to it. I've actually been noticing (for the
past few weeks on my S and now on my X that I just set up), that all HDR functionality on any media related apps are giving us the grayish letterbox bars and ugly haze over the picture. It's like all TV smart dimming functionality is gone, and the HDR is in
no way darling blacks or brightening colors. Something we'd see on a cheap TV with too harsh of a backlight. So I first noticed it when I popped Guardians of the Galaxy 2 in the player, 4K HDR and everything. But the bars were that grayish color, and everything
looks dull. Then I tried watching Netflix. EVERYTHING on there looks greyish too, HDR content or not. Amazon Video will appear okay at first, but as soon as HDR content kicks in, greyish black again, just like the others

So after running a ton of trial and error tests, it looks like any app that causes your TV to go into HDR mode (on my Vizio it'll indicate near my input at the top that it's switched to HDR10), the blacks and colors will be all off. If the TV doesn't switch
to HDR mode, you'll get nicer black on those bars, but the image itself is still SDR, not HDR. Netflix and Blu-ray will automatically put my TV in HDR mode on start up, so everything on those apps looks terrible. Amazon will only switch HDR on if it detects
the specific video I'm watching in HDR ready. SO as long as my TV doesn't switch to HDR, the image looks like an okay SDR image. As soon as it switches to HDR mode, regardless of the content being SDR or HDR, everything looks like ****. So needless to say...
somethings completely **** with all HDR enabled apps on Xbox right now, S and X.

I've all but confirmed the problem lies specifically with the Xbox Apps, because when testing my TV with Netflix through the Smart TV apps and not Xbox, HDR kicked in and looked beautiful. On top of that, all HDR gaming looks awesome
on the Xbox. So my TV is completely capable of giving me correctly displayed HDR content. It's just when you use an Xbox media app (Netflix, Amazon Video, Blu-ray), and the TV goes into HDR mode, and that's when we get some very off results. I swear this wasn't
the case before. Something must have happened in the last console update maybe?

Anyway, I think you should try out everything I did if you can, and if you get the same results, I'll be able to rest easy and know it's definitely the Xbox apps themselves that are causing the problem.

Josh, I can confirm the same thing, see the link I pasted into post below. It appears to have been fixed in the latest Delta preview, so hopefully will be released soon to public. Really frustrating, as I sold my LG 4k player because I thought, "Ah, my
Xbox can do all of this, why have a dedicated player..." Anyway, you're definitely not the only one with this issue, just search for HDR Black issue in the forums and multiple posts will show up.

Thank God! Thank you so much. You just spared me of more wasted hours trying to find a solid answer. This news makes me feel sooooo much better.
