Progression of wants to get better pq

How to chase the pq rabbit. Considering that the TV does a great job of upscaling to 4k, the pq improvements diminish as you go from $ to $$$.

Internal TV apps, like Netflix.
DVD and bluray movies on a bluray player.
Streaming services.
4k movies in HDR10 on a 4k player.
Apple TV.
4k movies in Dolby Vision on a 4k player (like a OPPO 203).

Watching a 4K HDR movie (Interstellar) and most scenes look absolutely great....but when it is really dark scene, it looks overly black...like too dark and not defined enough.

I'm using the sonoftumble settings with no other calibration...TV is only a about a week old so it doesnt have a ton of hours on it.

Room is not light controlled but I've noticed this in near darkness - OLED Light is set to 40 for HDR content.

I was curious if anyone was having this issue with their OLED and receiver. When I turn the TV off and it goes through its compensation cycle I set my receiver to my media PC through HDMI input and play music to sleep with. Once the compensation cycle is done and you hear the TV click to turn off the music cuts out and I need to restart the song and it plays fine from then on out. I turned ARC off but that didn't help. Anyone else experience this?

Everyone forgets how well the Oppo players hold their value, which allows you to move up to the new player for about what the less expensive models from LG or Sony cost.

Even if you don't need the "universal" functions of the player. Oppo is great - top notch customer service (they respond on weekends) and frequent firmware updates, which help with disk compatibility issues that appear to be even more prevalent with 4k Ultra disks along with other fixes/new features. Plus they keep pushing the updates out for years, not just until the new models are released. Still remember getting that firmware notification is available for my 83 - 5 years after buying it That's the one Oppo I've not been able to part with, guess since it was my first one.

You can also run your streamer of choice via the HDMI input through the Oppo to the LG - Oppo's video processing has always been top-notch.
smurraybhm, like you, I still have my trusty old Oppo BDP-83. It has DVD/Blu-Ray upscaling abilities like no other player I've seen. (Though, I've not seen the BDP-203 in operation.) My BDP-83 is my only disc player and it feeds directly to my LG OLED 55B7P. I don't subscribe to any streaming sources, so the 83 is my only source of program material other than the Comcast X1 cable box. I haven't gotten a 4k player yet, but when I eventually do, upscaling from DVD & Blu-Ray will be every bit as important to me as it is now, because I have literally thousands of DVDs & Blu-Rays, most of which won't ever be available in any higher resolution format. How would you compare the relative picture quality of the following "DVD to 4K" and "Blu-Ray to 4k" upscaling options ...

1. DVD: BDP-83 to LG OLED (letting the OLED do all the upscaling)

2. DVD: BDP-83 to LG OLED (upscaling on the 83 to 1080 and letting the OPPO do the rest)

3. DVD: BDP-83 to LG OLED (letting the OLED do all the upscaling)

4. DVD: BDP-203 to LG OLED (letting the 203 do all the upscaling)

5. DVD: BDP-203 to LG OLED (letting the OLED do all the upscaling)

6. Blu-Ray: Same basic comparisons, but with Blu-Ray instead of DVD

Additionally, can the HDMI input on the 203 accept an HDMI output from a cable box and pass it through to its HDMI out? If so, would "cable box to 203 to OLED" (with the 203 doing the upscaling to 4k) tend to produce a better picture quality than cable box direct to OLED (with the cable box, the OLED or some combination of the two doing the upscaling)?

You have at least 1 change from his recommended settings and it very well could be the cause of the overall dimness.

For HDR the default OLED light is set at 100. Sonoftumble decreases that to 70 and yours is set at 40. Bump it up to 70 and see if that takes care of your issue.

Basically I use internal apps for Netflix, Amazon, and Vudu. I have a Oppo-203 for Blu-Ray playback. That's pretty much it. I do also have an Nvidia shield but I haven't used it since getting my OLED and may put it on another TV. I used it on my old Samsung LCD because the apps on the shield were better than the apps on the TV and Vudu has HDR and atmos support on it. Now the TV apps do dolby vision and atmos, at least Netflix and Vudu so I see no need for it. I suppose I could use Kodi and Plex on it but Plex works on the TV app minus lossless audio which for the odd time I actually watch one of my BD rips, is probably fine with dolby digital audio.

I thought he said that his room was pretty bright / well-lit and that's why he set it at 70...I can try bumping it up. Will that potentially cause eye-strain?\

Wow, actually quoting myself seems somewhat arrogant

Received the new Xfinity XG1v4 4K DVR today. Set it up and have been watching Comcast cable on my 65 C7 for this last 4 hours. I must say, I have noticed an increase in PQ compared to the standard HD X1. I am using Technicolor Picture setting, adjusted based on @sono tfumble updated calibration settings.

The picture is markedly sharper and not as soft as before. I am pleasantly surprised to say the very least.

I did have some issues with stuttering at first when playing back a recorded show. I changed HDMI cable and the issue is no longer there. I was utilizing an older HDMI cable from 5 years ago. I upgraded and purchased these, https://www.amazon.com/4K-HDMI-Cable...=4k+hdmi+cable. These cables made all the difference.

I know there were replies on this subject stating no real advantage to this box. I can say unequivocally, this is not the case. The PQ is better and worth the upgrade.

BTW, I am not being charged extra for this box. So it really is a no-brainer. Not using this box for Apps. I utilize these in the TV which work just fine.

I think those comments were relative the default OLED light for Dolby vision settings. The DV default is 50 and he thought that was too dim and bumped it to 70.

The HDR default of 100 was too bright per him and he decreased to 70. I don’t experience any eye strain at 70 and wouldn’t expect it to bother most people, but you will have to see how your eyes like it.

It has perfect blacks which no LCD tv can match, it has perfect motion with no blur, according to rtings.com reviews the B7 and C7 get as bright during HDR scenes as the Samsung Q9F does but since the black levels are perfect and each pixel can turn off individually it allows highlights in dark scenes to stand out more and appear brighter. Burn in can happen but you can take steps to prevent this by varying the content viewed. If you watch a lot of network TV or news for many hours at a time then the logo may eventually get stuck. Most other content like movies and shows from streaming sources without persistent logos won't have this risk.

To be nitpicking... Apple has not released the support for the new DV profile used by Sony (and it was not a “fix” but a new feature). The new DV profile is only available as Beta software and as such has had the expected bugs one could have with a Beta and not recommended for general use.

If you have light in the room, 40 for the OLED setting for HDR is probably not going to be bright enough. Try 70 and see. Worse that can happen is...you don't like it an turn it down by ten and then even another ten.

Also, try Brightness at 50 rather than 48. That might bring out the details in dark scenes better for you.

Its good to see people talking about reducing brightness for HDR. Everyone keeps saying everywhere you need max brightness for HDR to the point I constantly felt like I was doing a grave sin by lowering it but I am like 4 feet from my tv in a dark room and I feel like I am going blind whenever a bright light source comes on screen. Since I am a gamer and that means white text, etc I felt like I was eye dropping every hour.

Part of the reason this is all odd to me is I had a KS8000 and it claims to be 1000 nits HDR and I had no issue with it at 100% but this display which is 750 HDR I find just as bright at 50%. Maybe my ks8000 was busted [it did have numerous problems] or maybe I am missing something.

The ks8000 is easier to adjust and remain adjusted to since the brightness of the picture remains “more” consistent than the oled.

The oled shifts it’s brightness around a lot. Partially due to ABL and partially due to the nature of the active HDR lg implements.

It’s not the brightness that causes the eye fatigue, it’s the frequancy of changes in levels.

Thanks for the info.

I've been on the fence about it because I've seen so many complaints... but if there's no extra cost I'm gonna call Comcast tomorrow.

Interesting...does the same go for DV content? Will try changing to 70 and see if that is better and doesn't cause eye fatigue.

40 OLED on SDR content seems about right for my room...nothing is washed out or too dark - and my eyes don't hurt after 90-120 mins of continuous viewing

^ I actually watched the 4k UHD disc of Interstellar this past weekend. Nothing looked overly black to me, but I'm using the Cinema picture mode at its default settings--OLED Light 100, Brightness 50, etc. I watched it in a dark room with dim bias lighting and I didn't experience any discomfort or feel like my eyes were being blown out (remember, it's almost a three-hour movie). My SO didn't complain, either. Just our experience and everyone is different. of course.

The reason why I'm using the defaults is because some recommend not changing OLED Light and Brightness in the HDR and DV picture modes because it screws with the tone mapping. I have nothing against sonoftumble's tweaking of these settings and he's given a reasonable explanation on why it's okay to do so; it's just that the default settings work for me, so I have no reason to tweak them.

Like others have suggested, try bumping up the OLED Light and moving Brightness back to 50.

BTW, like you, I also put OLED Light at 40 for SDR.

I just got the LG b7 at Costco yesterday and loving it so far! Couple of questions... Is there a page or spreadsheet with settings on this thread or what are the general consensus best settings to try?
The screen saver that comes on after a few minutes of not watching is this sufficient to protect against burn in?
Will these tvs get a software update like the new ones to be controlled by Alexa? Not sure if it's possible.
Lastly, what streaming box do you guys think is best for it? I have the first generation fire TV so I need to upgrade. I have an echo so the new fire TV might be the best option.

The HDR default of 100 was too bright per him and he decreased to 70. I don’t experience any eye strain at 70 and wouldn’t expect it to bother most people, but you will have to see how your eyes like it.
When I think about I how I ended up with my particular settings, I found that it was based more on what types of content I watched during the day vs. night time viewing. Most of the time you will find me watching SDR content during the day, and HDR/DV content at night. When the sun goes down, I can get the room pretty much pitch, so that would make more sense that I found myself turning down the OLED LIGHT to 70 for HDR technicolor, and raising it to 70 for DV Cinema (User) - ( 50 still just looks too dim ). Those settings are basically intended for a darker viewing environment.

For SDR, I have the OLED LIGHT set to 49, which not surprisingly works well in a med bright to bright room.

You might ask why the OLED LIGHT is lower for SDR than for HDR/DV even though that's a daytime setting? The simple answer is that SDR/HDR/DV use different scales and the HDR/DV thresholds start at a higher luminance level.

So now I can see the confusion that I may have caused. Keep in mind that my settings are generally middle range, so I think that they look great under a variety of lighting conditions. For me, it's a "set-it-and-done" kind of approach - or a happy medium.

QLEDs are LED tech and cannot hope to achieve the same stunning contrast as OLED, despite the name looking so similar. I wonder why Samsung did that ? They couldn't be trying to fool people into believing they were getting a product as good as an OLED, could they ?
Oled TVs do not go as bright as an LED can achieve BUT they can get too bright to watch comfortably unless you restrict the OLED Light in the Picture Settings. Some HDR games, however, may appear too dark but only the ones mastered at very high nit levels - say 10,000. This is because the TV will tone map in order to maintain detail and that will decrease overall screen brightness. Games mastered at more sensible nit levels will be unaffected.
OLED TVs can suffer burn in but I would say it is extremely rare. I have not read one post on here where burn in has been reported. I myself use my B7 as a PC monitor (where I have static images for a prolonged time) and I use it that way for about 9 to 12 hours every day, only watching movies in the evening. I have never seen any image retention or burn in and I have had the TV since June.
LG are quite pro active concerning burn in. After a few minutes of a static image the screen will start to dim, in increments, also there is a Screen Shift (optional) function which moves the static image slightly and there is also an automatic Pixel Refresh function that kicks in after each four hours of cumulative use. A similar procedure can also be triggered manually.
In my opinion OLED and not QLED is the way to go.

I'm starting to wonder if I have a defective TV. It seems like everyone is keeping their brightness at 50 and OLED/Contrast around ~70 for regular TV content. However, my picture seems extremely dark and I'm noticing a significant loss in picture definition for dark 1080p content. Is everyone just accepting the loss in picture definition for better blacks or should I be concerned here? I don't have Eco mode on and its not like I'm using the TV in a bright location -- its only used in a dark room with bias lighting.

I've attached a couple images to show what I mean. The first image is literally the stock Cinema(user) setting. Notice how a significant portion of the background is missing (e.g. trees are barely visible, statue lacks definition, etc.)? The second image includes the following modifications: Brightness set to 60, Dynamic Contrast set to medium, Gamma set to 1.9. Notice how there's now significant definition to the trees and statue? It's even more apparent in person. There's a mask off to the right top corner that is virtually invisible with stock settings and yet fully visible with the brighter settings.

Looking at your pics I think you have labelled them incorrectly. The first is the lighter one.
Personally I also prefer a lighter image but I think your lightest looks a bit washed out (difficult to be sure from photos) and I would probably see what it looks like with a Gamma of 2.2
Having said that I am a great believer that there is no right or wrong picture, only the one that is right for you.
Sure , I do understand that some settings are more accurate than others but that means very little if you don't like the images and your TV gives you the option to find something you like better. So I say, find what you like and ignore anyone who says you shouldn't use it. It's your TV and your choice. And I don't think your TV is defective.

Oops... sorry the pics are indeed reversed. I'll give Gamma 2.2 a try and see how it looks. It's just odd because so many people are using those settings and yet--to me at least--it's not even watchable. It looks much less pronounced in the pictures but in person it reminds me of a badly recorded VHS tape. There are times when you can't even see the persons clothes and it just looks like a floating head (if they are wearing dark clothes in a dark scene for instance). This is only apparent with poor quality content (e.g. Comcast, 1080P/720P downloaded content, etc.).

Are you playing content from a Windows PC ? I play a lot of content that way and initially found that I had badly crushed blacks which I hadn't suffered on my previous Sony LED TV. I went into the Intel Graphics Controls and set Gamma for all colours from the default of 1.0 to a setting of 1.2
Oddly increasing the Gamma Value in the Intel setting brightens the picture rather than darkening it. This brightening really helped for those picture modes with fixed gamma and my Gamma setting on the TV then fell into line with everyone else's. Just a thought.
As long as you can get a picture acceptable to you then I wouldn't get too concerned, I think any differences to others will be content and method of play related rather than a defective set.
