I have an LG B3 OLED that is at least 120Hz capable AFAIK.

Then AUTO should be the preferred setting for 24p output. Try disconnecting the power completely for a few minutes on all the equipment (ie pull the power cables as most power buttons are soft switches). If that doesn't work then try another HDMI cable. Also try disabling Dolby Vision - there seems to be various reports of flickering/blanking dispays with certain titles.

I'll try disconnecting the power. I got a new high quality HDMI cable but that didn't help. I tried disconnecting Dolby Vision already and that seemed to work so maybe that's what I just need to do.

Also, I just noticed some "unnatural" panning on a title with 24p output shut off so I put it back on and the panning was how it should be.

Could someone please explain to me that when you play a disk and you press the status button on the remote you have the codec for example MPEG-4 AVC and a constantly changing number next to it that can randomly go as low as 8 then jump to over a 100 in a few seconds.

It's the bitrate, there's one for audio and one for video. The higher the number the more information is being presented.

OK, finally got the 820 today! I originally ordered from Amazon early this week but cancelled it because the delivery estimate for free shipping was May 3-5 and I didn't want to wait over a week for it to arrive. So I went to Best Buy today and found a store that had it, and they price matched it to Amazon's $435.35 price.

So far, the player seems nice. I'm quite surprised how HUGE in size this player is compared to the 420. The 420 was nice and small, but also very noisy when loading discs. I'm very happy the 820 is nice and quiet. I tried some DV discs and some have more differences than others. Movies like "Wayne's World" and "Grease" have minor differences, but movies like "Mulholland Dr" and "The Ring" were pretty night and day. I was especially surprised about "Mulholland Dr". The HDR10 on that disc didn't look so great and pretty much felt like I was watching in SDR. Then finally checked it out in DV and now, the highlights pop out at the screen!! Pretty crazy difference there!

Anyways, now that I upgraded to the 820, what do you think I should do with my 420? Sell it or keep it as backup? I'm leaning more towards the latter as I feel it's always good to have a backup.

The 24 fps setting is interesting because it's not just for switching "On" and "Off" the ability to watch movies at 24 fps. It also changes the playback quality of the movies too.

With it "On or Auto," the content is played at 24 fps and played back at either 10 bit or 12 bit.

With the setting "Off," content will not be played at 24 fps but it will also be played back at 8 bit and not 10 or 12 bit.


You should be able to play those titles flawlessly. Do you have the player hooked into a receiver and that connects it to the TV or is it just straight to the TV?

I agree 100%. It's hooked directly to my TV as I don't have a receiver yet but that shouldn't matter should it? This really angers me. If I keep my equipment I'm always going to be wondering if I exchanged it would a different model/brand TV or player work like it should. This stuff wasn't cheap.

Do you know of a good tech support number I could call maybe?

Keep it as a backup.

Thanks.

Of course, now that I finally bought it, Amazon further drops the price to $419.99. Sigh!

I know it’s only $15 but still. I guess I could sacrifice a meal at McDonald’s and make up for it.

Not really. If it's spitting out 8-bit 4K60 then that's a bandwidth problem at your end, the player can only output what it thinks the TV/other gear in the chain can process. On a full bandwidth set then the Panny can output 10/12-bit 4K60 no problem.

That's odd, because I know everything in the chain is correct.

I just feel like I have heard somewhere the 24p setting is more than just for 24 fps "On" or "Off."

Plus, I said this many year ago in the Infinity War Thread:

https://forum.blu-ray.com/showpost.p...postcount=4607

Edit: I figured it out. What is happening is that when 24p is set to "Off," the player is converting the signal to YCbCr4:2:2 12 bit rather than YCbCr 4:4:4 12 bit. In turn, my LG C9 is then reading it as 8 bit YCbCr 4:2:2 HDR10 (This is for Infinity War.) This is also at 4K60p.

When turning 24p "On," player is outputting the picture as YCbCr 4:4:4 12 bit and the TV is reading it as YCbCr 4:4:4 12 bit HDR10, which matches up perfectly.

I wonder why my LG C9 is reading the former as 8 bit? Maybe it thinks it's like a Dolby Vision disc because I know DV reads like that on my C9.

12-bit 4:4:4 4K60 is too much bandwidth even for HDMI 2.0 which is why it's being output at 4:2:2, that at least is normal. What isn't normal is the TV thinking it's 8-bit. Yes, when outputting TV-led Dobly Vision then the 12-bit 4:2:2 image is 'tunnelled' into an 8-bit RGB signal, a legacy of DV mastering methods, but no such thing is or should be happening with HDR10.

I'd like to see another person who has an LG OLED see if those output readings are also coming up through the TV. (There is a way to see this via a trick to get the host/signal menu to pop up).

I guess the only other setting that I have Turned Off on the TV is 'Real Cinema" which does 5:5 pulldown. Not sure if that would have anything to deal with what we are talking about though.

Edit: I figured out out. I just read a post on Reddit and it says that there is a bug in the C9s interface. This seems to follow all other LG OLEDs too from what I am reading. The link provided was from AVS forum. Here is the quote:

Problem: The TV is reporting that image has 8bit instead of 10/12bit;
Conditions: -;
Cause: When the TV is getting a 4:2:2 HDR signal it is always reported as 8-bit even though it is receiving 12-bit. This is a technical limitation of HDMI. The only way to verify what bit-depth you are getting is to use test patterns. It's the same reason why Dolby Vision is reported as SDR. Because the TV doesn't actually "know" what it is getting.
Resolve: -;

We are talking about HDR10 discs and DV discs not registering right on LG OLEDs. DVDs may register right though.

I noticed today that my ub820 is warm in the middle of the player when it is off. Not hot but a little warm. Yet, when it’s on or I disconnect the power cord it cools down. Any thought?
