So can anyone confirm if Auto Local Dimming set to High is bugged, or is it actually working as intended? Basically with it on High, if there is a small bright box in the center of the screen, it is actually dimmer than with it on Medium. Not only that, but setting it to High also seems to mess up the white balance and clips some whites! It's very obvious on certain images if you switch back and forth between the settings.
It doesn't seem to be a big issue leaving it on Medium, but it definitely doesn't let the screen get as inky black as it can on High (hard to notice in normal usage).
I noticed a couple of posts in this thread refered to this same issue but the discussion never went anywhere other than "Medium is the proper setting".
So in summary, firmware bug or working as intended?
This is working as designed. For accuracy of image, you set it to Medium. If you care more about blooming, you want it set to High.

Luckily I don't notice blooming even on Medium, just sometimes larger black patches exhibit that ever so slight backlight glow, but even that's only noticeable in a completely dark room. I just find it strange the High setting screws with the white color balancing and not just brightness...

P.s. I'm just being nit-picky, I still love this set and think it's one of the best you can get at this price!

I agree, it's probably as Sony intended.

I would also add that Medium is the setting you want to choose for the brightest HDR. If you have letterbox bars on a movie and notice too much flashlighting from the corners of your tv, or the bars seem too gray, then that might be the one time to go ahead and use High (but I usually don't).

That's why the settings are there, to adjust to your liking.
Knowing what the 'right' settings are supposed to be is good... But if you prefer something different, then it's your choice.

Know back in the day the 'right' brightness and contrast made for a pretty dark picture... Usually ended up cranking them up a couple notches (way down from torch mode, but still up from calibrated).

Guys i have a really bad feeling about this 4k 120HZ issue. When i updated my TV a few weeks back manually the patchlog said:

„activates support for 4K 120Hz“

Now it says

„activates support for 4K 120Hz signals FOR PS5“
There may be a glitch or two when these gaming systems come out. What do you all think?

Anyone else experiencing random reboots, frozen screens, and clicking noise from time to time after the update? Driving me nuts on my 2 week old TV.

I wish they would figure out the motion bug !
Put motion and other settings on AUTO. This TV has great motion interpolation which is AI enhanced. There is no blurry trails nor soap opera effects like on older TV's. It works great and I leave it on.

I would also add that Medium is the setting you want to choose for the brightest HDR. If you have letterbox bars on a movie and notice too much flashlighting from the corners of your tv, or the bars seem too gray, then that might be the one time to go ahead and use High (but I usually don't).
There is no difference HDR brightness in medium or high backlight setting. I measured with my X-Rite i1 Display Pro. Same 600-700 nits on my TV. If you want higher HDR, you set the contrast enhancer to high and max out the other settings.

On the TV go to Settings > Remote Control > RS232 > and change the type to "serial."

TV will reboot and that should solve the random power ons. There is a bug with the TV and it defaults to HDMI and Off doesn't seem to work.

You can try enabled Simple IP Control > ON (or something similar) to see if that helps. Similar function to the RS232 function.

Settings -> Watching TV -> External Inputs -> Advanced Settings -> RS232 Control (Off or HDMI)

SNIP-

Sorry but I have to disagree on this. This might be true full field but using contrast checkerboard measurements or in real scene content where dimming zones are involved in keeping blacks "black" the ALD Settings of High clamps down on brightness. For example, the attached HDR video scene of the egg at the16 second mark demonstrates this to the eye easily if you toggle between High and Medium. When measured, you'll find that High drops the peak highlight on the egg by @18%, 219 nits down to 178.

Toggled simple ip on still got the clicking noise.

Yes i found the RS232 options on eu version but we are missing the serial option which has said to help with clicking the hdmi and off option doesn't help with that. If you were just telling where the options were then yes they are there.

It's annoying, and it makes me think it's bad news. You don't delay good news in today's society.

The great news is, if you copy your original settings down, you can always go back to were you where.......

So I'm trying to compare some hdmi cables (recently received some zeskit cables) and I'm having trouble figuring out how to get the sony tv to confirm it's receiving a dolby vision signal.

I'm playing through an nvidia shield connected directly to hdmi4. I have the external inputs set to enhanced mode, with the setting selected for dolby vision of course.

In the nvidia shield, display preferences, I normally have it set at the dolby vision 4k mode where it was 60hz or 59.940hz, and I've tried the 23.976 as well. Same thing, I'm not seeing dolby vision logoed on the tv.

The dolby vision chameleon video at Dolby Trailers – ATMOS, Lossless TrueHD 7.1, AC3 5.1 always looked a little funny to me in the box where dolby vision was selected, the colors always appeared really saturated. I just didn't worry about it, movies looked fine.

Since I'm scrutinizing video quality of cables, I wanted to confirm the tv was receiving a dolby vision signal. If I press the display button on the remote, I never see anything mentioning dolby vision. Just hdr10.

I also notice there's a sharp snapping sound coming out of my speakers whenever I stop playing the video, and the color of the chameleon changes briefly, whenever I'm exitting the video.

I'm really dubious about these zeskit cables right now, but I'm curious if there's a dolby vision related setting I'm missing?
