This thread moves a little faster so i'll ask here vs the C8 thread. I just picked up a 65" C8 and its just incredible. My question is on the tone mapping of hdr modes, is theres a different way of tone mapping from mode to mode? Which mode prioritizes brightness over preserving detail? (similar to hdr bright on the '16 oled's) So far i really like technicolor for hdr 10 but im wondering if standard or cinema home are/should be brighter? Thanks!

The EDGE ENHANCER controls ON/OFF for SHARPNESS setting.
You can easily test this:
Turn EDGE ENHANCER to OFF, then change SHARPNESS and you will not notice any change.
Turn EDGE ENHANCER to ON, then change SHARPNESS and you willl see a big change in SHARPNESS.

I leave EDGE ENHANCER ON.
@Soundizer17 - Good Call!

This setting really helps improve the PQ with lower rez 720P/1080i signals found in broadcast/cable/sat sources.

My understanding is that tone mapping changed significantly in the 2018's. I think you really need to ask in the other thread.

These settings are found under the "Expert Controls" menu inside the picture mode settings menus. Eg. Picture Mode Settings / Picture Mode:technicolor Expert ( or Cinema ( User) / Expert Controls / White Balance / Method. Change the Method between 2 point and 20 point.

Do you have sharpness set to 10 in every mode including Dolby Vision? Or to 0?

I know it's not exactly OLED related, but i'm fascinated by how streaming picture quality is noticeably better on Apple TV 4K compared to the native apps. Why is that again? Is it because Apple compresses it differently when streaming, combined with their processor for the ATV4K?

I realise this might seem like a crazy question, but is there any way you can stop the "Dolby Vision" logo from popping up every time the LG detects a signal? It wouldn't be so bad if it was just once but it pops up 4 or 5 times per disc (on insert, copyright warning, studio logo, menu... and then most annoyingly of all... when the movie starts (HDR10 only pops ip once normally, when the disc is inserted)

I’ve been buying 4K movies on Apple TV 4K. Randomly bought the LG UP970 this week and it’s definitely sharper image coming from a physical 4K disc but I’m torn because there are more Dolby Vision movies on streaming services than there are on 4K Blu Ray discs.

Debating wether to keep the LG UP970 and switch to physical 4K Blu rays from now on or whether to return the LG UP970 and keep buying streaming 4K titles on iTunes.

Any advice? Has anyone evaluated this too?

With active HDR, HDR10 titles look great and thanks to higher bitrates the picture is sharper with less noise in dark scenes. Keep the player. You get the digital code with the disc purchase anyway.

So I noticed something that happened a couple times to me while gaming and I don't know if I can eliminate it. When playing Xbox One in HDR for a time I sometimes get the screen to go very dark. Like some screensaver kicking in. Going to the TV menu forces the TV to go back to normal brightness and then I return the game and the brightness levels are fine again. Is this the TV or the Xbox and what causes it exactly? Is it a setting or something I'm doing that causes the TV to kick that on? It's only happened a couple times and I can't think of the situation that caused it.

I hear ya. I do have an Xbox One X so I’ll use that for the 4K blu rays I already purchased. Returning the LG UP970 today tho.

I compared Argo 4K Blu Ray disc with HDR10 vs Argo Apple TV 4K with Dolby Vision and it looks better on the Apple TV 4K thx to DV.

Whatever...gonna call BS on it looking better streamed lol. I think you're just trying to justify the Apple TV. Same as people saying it looks better than the internal apps. It's fine...you asked and we answered. If you were just gonna return it why did you even ask?

Good luck with that. If you go to the MS store and read the reviews on the X blue ray app you might change your mind. 1.5/5 stars with pages of complaints related to audio syncing... the same problem I had which had me getting the 970. I’ve had no further issues since.

The X blue ray app is garbage. You’ve been warned.

As for discs... they are the better buy and as others said you get a digital code anyway.

I can’t say I agree with the 4K discs being a better value. iTunes is constantly running sales. I bought 2 4K dolbyvision titles yesterday on iTunes . Independence Day for 5 bucks and the revenant for 7.99. Also today bought the new planet of the apes movies for 7.99 each. All 4K dolbyvision. The 4K discs are 20 bucks each. Also all titles I had already that are in 4K were upgraded. To me that’s the better value. The streaming quality of the atv4k is plenty good. Disc could be better but I doubt it’s 2 to 3 times the cost better. Just my opinion

If you're never buying brand new releases at launch then maybe. New releases to own on iTunes are around $20. Sometimes the disc is $20 and at most it's $30 in my experience. For that you get two discs and the digital code. Better value. You're also not locked into the storefront you buy the movie at. You can stream it on something other than iTunes or Vudu etc if you redeem it in movies anywhere.

If that's not it, of the 6 or 7 HDR titles I've played only MHW seems to dim or brighten occasionally about 5~10% for no reason, and sometimes the TV does not recognize it as HDR, but then suddenly it will, but only that title.

Agreed... and that's what I do. I've bought 60+ UHD discs in 2 months of OLED ownership and all but 2 (Dunkirk, Coco) I got for $15-$25. I've gotten most around the $15 range with quite a few being from Amazon's never ending 3 for $50 sale.

I just can't see the point of going streaming only due to the lesser quality and more importantly being locked into the store I buy the movie at. With the disc purchase I get the UHD and 1080p disc as well as the digital code for redemption. To me it's a no brainer.

Also, save money by renting, not buying. I caught up on several movies recently by renting them on VUDU through the TV app on the B7. They were all in Dolby Vision and they looked fantastic. I expected to see some banding or compression artifacts in Bladerunner 2049 and It, but if they were there I never saw them. The quality was excellent.

When it costs $10 to rent I'd rather pay the extra and own it. I do like having a bit of a collection of movies on the shelf too. The big deal for me is lossless audio though. Can't get that digitally. The audiop is ok off Vudu but lossless has better LFE in my experience.

Debating wether to keep the LG UP970 and switch to physical 4K Blu rays from now on or whether to return the LG UP970 and keep buying streaming 4K titles on iTunes.

Any advice? Has anyone evaluated this too?

Why is it an either/or decision? Keep BOTH, that’s why most people do here. You can use digital for convenience and to get titles that don’t have discs and the UHDBR player for watching the best version of available titles. Some enjoy digital only, but they are willing to take the lower quality for convenience.

Who's the they in "That’s what they have been calling it" and in what context? Certainly not Dolby or LG or even Sony.

I understand you to be saying new profiles when you say "latest profile3" and Dolby is not releasing new profiles. They're fixing bugs in existing profile "decoders". LG waits for a firmware drop with fixes from Dolby and we wait for a firmware drop from LG. If you mean bug fixes when you say "latest profile" then we're just using differing terminology.

Quote:
  • A Dolby Vision profile is composed of:
    • A video codec profile (such as HEVC main10).
    • Its associated standards-based video elementary stream metadata (such as High-Efficiency Video Coding [HEVC] video usability information [VUI] and/or supplemental enhancement information [SEI] messages) used to encode one or two baseband video signals (a base layer and possibly an enhancement layer).
    • Dolby Vision composer metadata and Dolby Vision content metadata carried and encoded in a specified fashion appropriate for the codec
There's a (short public) list of profiles. Other than adding MEL and deprecating old profiles it hasn't changed in some time.

I might type 2K for 1080p.

Is this the TV or the Xbox and what causes it exactly? Is it a setting or something I'm doing that causes the TV to kick that on? It's only happened a couple times and I can't think of the situation that caused it.
What you are seeing is ABL kicking in to keep the panel from getting too warm. You'll see it happen more often with static images.

Hi guys!

Quick question:

i am an apple fan and I am thinking of buying the Apple TV 4K. The plan is to use Apps tv together with Netflix or other apps.

So my question is: will I see a difference in visual quality when I watch a movie in Netflix via the Apple TV? I am thinking of dolby vision movies..

Thanks!

I'm calling BS on your BS. Streaming has become so good that it is getting very hard to see the difference vs. a disc - especially when DV is part of the streaming source vs. an HDR-10 disc. In fact, you pretty much have to freeze the same frame and compare side by side to notice much of a difference - which will still be subtle - and not the way we ( me ) would watch a movie anyway. I still buy Blu-rays for recent reference examples or re-mastered classics - but after watching Vincent's AppleTV 4K vs. Blu-ray comparison - I no longer stress about depriving my eyes from experiencing great picture quality if I watch a movie on my AppleTV 4K. And it doesn't have to be an AppleTV. The built-in apps look great as well.
