UHD and HDR in General

[A Tempted Christ]

What went wrong here?

[James43]

Well that's certainly not a good idea. Set the output to UHD Auto so that your UHDs are played back at their proper 24fps. You also may need to engage a setting on the TV to ensure it isn't converting to 60hz either, on LGs it's Real Cinema for example (I think it's maybe Cinemotion on Sonys?).

Thank you, EddieLarkin. It worked. In fact, I have ignored the HDR setting on my Panasonic OLED TV and it‘s True Cinema in this case.

I gather that the next few weeks are a good time to be buying a 4K TV. I'm pretty sure I want 1) the largest and highest quality screen currently available for watching films (so an OLED?) and 2) to mount it on a height-adjustable mobile cart. Any suggestions for either of these?

[EddieLarkin]

2022 will be the first year that a new type of OLED panel will be released to compete with LG's (so far all OLEDs regardless of brand have carried LG's panels). This is the "QD-OLED" panel from Samsung, and Sony have announced they will feature as part of their 2022 lineup. How they'll compare is unknown so far but on paper they appear to be superior. But at the same time these new technologies always tend to perform quite poorly in the first year or two, as they work out the kinks, so if you wait a year you may find yourself waiting even longer.

But if you're happy to go ahead now then the Sony 83 inch A90J is the biggest and best you can buy:

[swo17]

Thanks! Yeah, I don't want to wait several more years. Pairing this with the few-years-old Oppo UDP-203, are there any capabilities I'd be missing out on?

[EddieLarkin]

Nah, you'd have basically everything covered. Though if you're going to spend that kind of money, it would be foolish not to add a few hundred on top for a professional calibration.

[swo17]

Good point, how does one go about finding someone to do that?

[EddieLarkin]

Probably the best place to start:

It's common to rely on other people's recommendations but I can't help there being in the UK. This is probably a helpful thread though.

[swo17]

Thanks again!

I purchased an OLED recently and while I can see all the advantages of the tech, particularly in terms of black level and contrast, I ended up returning it due to horrible screen uniformity. The edges of the screen had a pink tint to them that could not be remedied through calibration. In color content it wasn’t noticeable but it had a ruinous effect on B&W widescreen films. If you check out the OLED banding and screen uniformity thread on the AVS forum you will see many examples of the issue. Apparently it is most prevent in the 65” models produced in the last year. I’ve decided to stick with my now five year old Sony LCD, and after a month of trying to live with the OLED I was shocked at how much better the LCD looked when I hooked it back up and put on a B&W film. Both techs have their strengths and weaknesses for sure, I just found I was more willing to forgive the defects of the LCD.

[swo17]

If I'm looking at the right thread, it's 18000 posts of technical info that's a bit challenging to wade through. Is this an issue with the specific model and size EddieLarkin recommended?

[senseabove]

From what I gathered during my few weeks of reading a metric fuckton of threads on OLEDs there and elsewhere, it is basically an inherent risk with OLEDs. LG makes all the OLEDs that both LG and Sony use in their TVs, but Sony gets first pick on displays and LG uses what's left. So, given that, anecdotal evidence seems to confirm that Sony's getting the higher quality ones, and the risk of banding/uniformity issues is significantly lower, though not totally absent, with their sets. If you look at the LG OLED vs Sony OLED threads, you'll see that it seems like 60% of the LG posts are about "will 100 hours of color flashing and a hard pixel refresh fix this display issue?" and maybe 10% of the Sony thread is that. That was, ultimately, the thing that pushed me toward spending a little extra on the Sony.

[swo17]

Interesting, thanks

As hungry as I am to go 4k, this makes me not want to give up my 2015 Samsung plasma.

[EddieLarkin]

Bear in mind you'll never get stuck with a bad panel, you'll always be able to go back to the merchant and report it as defective, so they can swap it for a different unit. Which obviously is going to be inconvenient sure, but I've owned both an LG and Panasonic OLED and neither exhibited noticeable real world uniformity issues (and I watch a huge amount of b&w content), so the chances seem fairly small.

[subliminac]

I agree with the comment senseabove made. The TV I ended up returning was a Sony A80J and I think what led me to settle for a return as verses an exchange was one professional calibrator’s remark that he had seen the problem I had, to varying degrees, on every single 65” OLED panel he had calibrated that was produced in the last year. This was on both Sony and LG models. I was concerned I was going to end up in a fruitless cycle of exchanges so I decided to settle for what I knew I could live with, my old Sony LCD. Now LCDs can have their own issues in regards to screen uniformity too. Each tech seems to have its own issues. If I were still in the market for a new TV I would definitely have to prepare myself for the fact that it may take a few exchanges to get something I was satisfied with.

[swo17]

But presumably only if you buy the warranty? And don't buy from an online seller that's offering the set at a large discount? (Although that Greentoe site is supposedly legit)

[subliminac]

You’d have to buy from a Sony authorized dealer. I believe their website provides a list of vendors that qualify.

I notice the B&W “pink” on my OLED only when I get up and go to the bathroom or something. It happens if I’m looking at the screen incredibly off axis. I’ve never noticed it while actually watching something, but I do have the luxury of always sitting directly in the middle of the screen or close to it. B&W movies look amazing on this, and I’ve had many more ‘wow’ moments w/ old BW Blu-ray’s so far than UHDs (I’m coming from a Sharp LCD to LG OLED). I would even go as far as to say when you first get one don’t go for the ‘wow’ discs or even 4k right away - put on something like the old Lady Vanishes Blu-ray and the improvements should jump at you. I am eating major crow having been one of those “I don’t see it” people until I bought one and spent some time with it on my own with my own collection.

Sounds like you might have one of the newer evo OLED panels that is on the Sony A90J and LG G1. This is a newer panel that LG is manufacturing that is capable of higher brightness and was initially reserved for the higher end models, but apparently it has trickled down to some of the Sony A80Js and LG C1s as well. The far off axis pink tint is the give away. That was not what I was seeing on my A80J. It looked more like this photo I found on the AVS Forum:



Granted it wasn't this pronounced in actual content, and the photo being over exposed makes it look worse, but this was the general pattern I was seeing when sitting dead center in front of the screen, and it was very prevalent in widescreen B&W content. I'm not sure whether or not the evo panels are less prone to uniformity issues like this or not.

[bfaison]

Holy crap that’s bad! Is it weird if I asked where you bought it? I got mine at Costco, it’s definitely an “EVO” panel too. Like you I went through the different slides and test videos and mine is not pink at all like that. I guess I got really lucky - hopefully you get a good one if you decide to try again.

[hearthesilence]

Sweet Jesus that reminds me of the shitty CRT TV's I grew up with. For whatever reason they were marred by long, giant splotches of discoloration.

[nitin]

the only comment I will add is that Sony's image processing shits on LG and Samsung, and if money is not an issue, a top tier Sony LED or OLED will do you just fine.

Amazon just dropped the price of this bad boy by $2000. Or do I pay $700 less still going through Greentoe? Puzzles, puzzles...

[bfaison]

I’m sure you’ve noticed but the $2,000 price drop seems to be happening at most retailers, so you’re not limited to Amazon. Although I’d be interested in your experience getting a TV that size delivered through them.
