    I have a new Sony Project VPL vw675es and the picture for the Masters channels is crap. Dark and not sharp. My projector support HDR. This is DirecTV’s issue, not ours.

    I've been watching 105 and 106 all day, and the PQ is outstanding. Using an LG OLED 65" TV, which supports HLG HDR perfectly.

    PS - I had my TV professionally calibrated early this year. This makes me think that TV settings for HLG HDR may not be correct on people that are experiencing this problem. If it helps, my baseline settings are "ISF Dark Room"

    Your second wide shot looks more like real life, with maybe a bit too much contrast. Maybe that's the problem - the HDR is too much like real life.

    How do you know your tv supports HLG HDR? I have a TCL 55P605 that I know supports HDR, but haven't upgraded to 4k for DIRECTV yet.

    I found on the Samsung there is an option to alter the “HLG” settings when it is receiving HLG content such as Directv 4K channels. It goes from -3 to 3 and the default was set at 0. Moving it up to 3 helped out the brightness of the picture.

    HLG is a pretty simple format that just changes the step sizes (that's the "log" part of the name) of brightness to be larger for higher brightness values - and also starts the brightness scale lower at lower values. There's room for interpretation of exactly how the scale works both on the broadcast end and the display end, so it makes sense you'd need a way to tweak it on the display end. No HDR format (except maybe for Dolby?) is intended to be an absolute scale designed to allow broadcaster / content creator to specify an exact brightness level that will seen by the viewer.

    That's really no different than ordinary HD broadcasts, which is why TVs have a brightness adjustment. If you have a LCD with a really bright backlight that might be nice to crank up to 100% if you watch it outside on a sunny day, but if you watch it in a home theater with no windows you'll want it at or near the minimum level.

    While there is no flag that pops up, like Dolby Vision or HDR. The TCL 55P605 does pass the HDR test that is in the settings menu of the C61K. The picture does not darken as it does on my Vizio P series which also passes the test, but does display and HLG flag. My Sony 900A does not pass the test, since it is a pre-HDR set. The Sony also does not darken while watching 104 - 106.

    I notice the darkening of 4k channels on my new LG TV, too. Possibly some odd HDR issue?

    Directv supposedly rolled out an update yesterday fixing the dim 4K picture.

    4000. Like I said, it did nothing for me. Only difference is they removed the channel logos.

    Yeah, it's Directv's HDR. Before, when I put on Ch. 104 the picture was great, and there was no HDR logo on my picture profiles. I had to turn HDR on within each profile. After the update from hell with the new guide, Directv itself turns on HDR which makes everything dark, muddy and with a brownish tint. This new update doesn't do anything for 4K, it only "improves" the guide.

    Right because Directv can't turn on HDR, so you're getting just a pure 4K picture.

    I just got a 4K mini installed today, and am getting HLG fine on both channels broadcasting live right now. Both my HR54 and the mini updated in the process. I actually found the picture to be washed out looking before I created a new setting for DirecTV HDR.

    Guide is now tagging 4K shows with HDR if it has HDR. Not sure if it was doing that before or not. I have the new update and have only tried a non-hdr show and for it the guide was normal (not dark).
