Letterbox bars going grey on Dolby Vision UHD

[bendermac]

I've watched The Hunt for Red October on 4K UHD with Dolby Vision and in a couple of scene the black bars turned kinda greyish. They were really noisy. A similar thing was with the movie Skyscraper. Is this a problem with the Dolby Vision layer?

If someone with the movie wants to check, jump to time 2:02:30, underwater shot of the passing by sub.

Playback with a Oppo UDP 203 on LG OLED C7 - Both Devices are on the current firmware.

UPDATE 1

Geoff told me on how to disable Dolby Vision with the Oppo and after testing it, I can confirm that this is a problem with the Dolby Vision layer. When the movie is played in HDR10 the black bars stay solid black.

UPDATE 2

After I've changed Dolby Vision Processing from Player-led to TV-led, the black bars are now solid black

I'm not the one to ask because I don't have a DV television, but yes this is an issue many people have had. With a C7 you should have good tone-mapping on the TV itself I believe, so maybe try out HDR 10 mode.

Is the C7 updated with SW File (Version 04.71.00)?

Oppo should be UDP20X-60-0625

The TV is at 04.70.85 - Firmware Check says "No updates available". But this might be just a different number for US Region vs Germany.
The Oppo is up to date

As for stripping the DV: Not possible. When DV is available, the Oppo isn't able to switch to HDR10. I've already tried that.

[Geoff D]

Set the HDR to Forced then power down the player. Power it up again and it will play DV discs in HDR10.

[bendermac]

Thanks Geoff. I'll try that.

#UPDATE# see first post

I like the theory of Dolby Vision, I really do.

The problem is, I've yet to see a satisfactory presentation. Maybe it's just my TV (LG LED), I don't know, but Power rangers has elevated blacks and Star Wars The Last Jedi had annoying brightness shifts on my TV.

HDR10 might have not have dynamic metadata, but it just works for me without issue.

There's an issue with LG TVs having elevated blacks. There's supposed to be a firmware fix, not sure why the OP hasn't got it. I was fortunate enough to have that update come through about a week after purchasing my first DV-capable player, so I've never really had to deal with the problem.

[oddbox83]

Mine's a 2016 LED model. I guess they won't be fixing it now.

[koberulz]

Mine's 2016 as well.

bendermac already verified he is using the latest Deutsch software for his LG OLED model which does address that issue. (04.70.85)

That's an earlier version than what you asked about though, which makes me wonder if that update didn't get released in that region, or if there's some issue with their TV specifically not realising there's an update.

Do you not realize that each localized LG marketplace has different software release versions? Also they don't have the exact same model codes either. In this example its for the 55/65C7 models.

Australia = Version 04.70.71
USA = Version 04.71.00
Germany= Version 04.70.85
UK = Version 04.70.95

Canada is still on 04.70.50

Canada is the same as the USA. See https://www.lg.com/ca_en/support/sof...P&superCateId=

Please note that is for a 55/65 C7, if you have a different model then it would be different.

Weird, Not what I was told. I called LG and they said it’s a different firmware. I thought the B7 would have the same update as C7

On the other hand, OP is having the exact issue the update supposedly fixes, which would be pretty odd if they were in fact up-to-date.

Hardly an unreasonable thought.

There was a lot of people providing links to beta FW a few months back instead of waiting for the official release that fixed the floating black bars issues. Saw that on AVSforums and AVforums as examples.

The beta software could not be updated to the official version as a FYI. Functionally the TV sees it as the same.

Your really reaching.

Unfortunately there is no reinstall possible for a consumer, unless LG puts out a another software update.
