Thanks about the tip for iPhone users on the remote app!

BTW I discovered that the TV does not like large flash drives. I had loaded the software onto a 16 GB drive and the TV never would recognize it, moved it to a 4 GB drive and it found it immediately.
I used 64GB driver (USB 3.1) and it worked fine for up\downgrading . I also rolled back to 0.15 . I hope it won't take long for LG to fix black crush and receive even better solution for the flashing issue and while doing so , also improve near black

16GB Sandisk kept failing part way through install but a 4GB Datatraveller worked for me first try this morning. Guess it depends on the drive.

What player are you using and is it's firmware updated?

While OTA wasn't pushing through to my set either, it is available as the latest public version on the LG website, so uploading it through USB is definitely an option.

I’m using the Oppo 203 wth the latest firmware update. I did some experimenting this morning and found that HDR 10 (with and without dynamic tone mapping) and SDR work flawlessly. Dolby Vision on my ATV Netflix had some black bar noise with brightness of 50 but resolved at 49. DV on the Oppo must be at 45 brightness to not show a gray black screen. I’m fairly confused at this point

Are you sure whatever material you are using as a reference is true black ? I have the 77” and don’t have that issue . You should only be adjusting black level with a pluge pattern. Also it takes a number of hours for the blacks to settle down on these sets. There is also a documented dv issue with raised blacks . My advice is to relax let the set get some hours , constantly changing settings will not end well .

What I’m judging all this on is my previous experience with oleds as I had an OLED e6 previously and never ran into this issue. What I’m looking at is the screen saver on the Oppo where the logo floats around a black screen. I am definitely willing to put some hours on the set and won’t adjust anything. I am going to magnolia today to see if my Oppo player does the same thing to their demo tv. I have not done anything with the firmware since install and don’t plan to until the new fw found successful (currently at .15).

I wouldn’t be judging black level based on a screen saver , have you seen raised blacks in actual dV content ? Again using a screen saver is not the proper way to adjust black level how you can you be sure that is true black ?

What is confusing to me though that screen saver has always been pure black with the old set and with the new set in HDR 10 and SDR. Currently in DV I have not noticed a ton of raised blacks.

^ I have also noticed that the overall brightness of the picture in Dolby Vision is significantly less bright compared to HDR 10. I know the OLED light is at 50 on DV compared to 100 for HDR but I don’t recall the image being so dim on the e6.

Try the Cinema home mode for some extra brightness not accurate tho , on my set DV is actually slightly brighter on a 10 % window after calibration . The tone mapping is way better on the hdr modes compared to the 2016 sets. I had a c6 night and day difference imo.

It may be just that particular drive, not its size. I use a 2TB drive with no issues on mine.

In a nutshell...what are the main differences between .31 and .55 firmware? My biggest concern has been shadow macroblocking and posterization with satellite SDR.

There is an audio fix and a fix for the contouring issue , the super bit mapping feature was broken by the .31 update . I wouldn’t expect any improvements in those other areas with this update.

Hi looking for advice for a problem I am having - I understand people were not able to answer it because it seems related to my Verizon One box not the TV itself. But I have a different question I was hoping I can get advice on.

For some reason the FIOS Box is stuck on outputting an HDR signal no matter what setting for resolution I set the STB on. As a result, my C8 is showing HDR Picture Modes, even though I am watching regular HD content. I have tried a bunch of things but cant seem to get the box to stop outputting as HDR and triggering the HDR Picture Modes on the TV.

So now I am just trying to figure out how to best choose and tweak the LG settings. Does it really matter that the STB is outputting as HDR when its non-HDR content? Should I just choose one of the LG's HDR Picture Modes and then change the settings to something like the ISF - Dark or ISF - Bright Room settings on rtings.com? Meaning should I manually just lower the OLED, Contrast, etc. so their recommendations, instead of keeping them at the higher ones typically suggested for HDR modes when viewing true HDR content?

Can someone please advise me on whats the smartest way to use the HDR settings I have to display for this signal?

Thanks.

I have Motion Pro off and I am still seeing a little "Soap Opera Effect" on panning and people moving. Could there be any other processing going on besides Motion Pro that would cause SOE?

Were you able to get into the hidden menu settings on the VMS/IPC4100 as I previously suggested?

EDIT: Also, in the Verizon forum, this seems to be a problem with the Mini/Client and not with the VMS. If you have the mini, switch boxes with the VMS or vice-versa.

Try going online to Verizons site and do the online check of your cable box. It may just need to be reset

I stopped over to Magnolia with my Oppo 203 and tested it on their display C8 77 with old FW and the same scenario occurred. Not sure where to go from here. Maybe replace the Oppo for a Panasonic or just wait and see if a future lg update fixes it.

Thanks for the string of responses.
Yes I am trying to have Verizon fix their box.
Yes it seems to be an issue with the mini and not the VMS but the problem was the Mini was not working properly on my other TV which is why they made the switch. The other TV is an old, non HD set and my guess it the issue there may be related - its not outputting 480i properly and the old TV cant consume that.
Yes I did get into the hidden menu as you suggested - I saw a lot of menus that showed settings which I didnt really understand, but also they were not mostly changeable, it was just a report of box settings. But it was very technical and I didnt see anything relevant - unless I didnt do it properly? Any ideas what I should search for and under which of those hidden menu submenus?

Separately though, while I am working with Verizon on addressing this (as you can imagine, this will probably take some time), does anyone have advice on my settings questions? Im just trying to figure out which of the Technicolor, Cinema or Cinema Home I should be using and what settings I should be tweaking them to, given they are HDR Picture Modes but I am viewing non HDR content?

Thanks again for all the input.

Sorry I am confused you are going to replace your Oppo because the screen saver is not pure black ? To me that seems a little extreme , what exactly do you think is wrong with either your player or your tv ? I am not even sure the oppo stays in Dv mode when the screensaver activates . I am having a hard time understanding what the big deal is if it’s not present in content . You are still making all of these judgements with a set that is still breaking in and without looking at any calibration patterns .

^^ This.

At this rate I'm worried that perhaps we'll need to post it 100 times, one for each hour of break-in period?

The black levels are noticeable during viewing content. The salesman at Best Buy also agrees with my assessment that this is not normal. I understand your viewpoint on the set not being broken in but it is 100% repeatable on a tv with thousands of hours on it. It also completely disappeared with a brightness of 45 (same as mine). I can try and take some pictures if that would help further explain my concern. The screen saver is in Dolby Vision as the LG does not change picture settings when going in and out of the screensaver. The reason I would change is Oppo is no longer sending out fw updates to my knowledge and having to turn down the brightness that much does affect the overall picture.

I understand what both of you are saying. Like I said above, this was the exact same performance on the demo set at magnolia..... not a break in issue. The calibration is the only other scenario that I can’t test yet.

Best Buy salesmen are not reliable that is for sure , the only possibility I can think of is a video level mismatch when your player goes into DV mode . What is the video range(black level)setting on the lg when playing dv content , the choices are usually low or high also what are the settings on the oppo ?
