An expensive TV is a poor investment, and people spend FAR too much on them

I think the idea is you only pay full cost for the first one, then after that you buy a new one and flog off the previous one. These things retain a good resale value, so effectively your $1000 phone is only costing you $300 or whatever. Once over that initial cost hurdle it's pretty much the same as a mid-range Android device from there on.

It is a sad fact that any display technology where image production comes from the varying brightness of elements that have a finite life is - inexorably - prone to burn-in.  Any mechanism to address such artefacts cannot rejuvenate the impacted elements (well, not that I am aware of) - which leads to the conclusion that whatever those mechanisms might be, they are quite likely reducing the overall life of the panel.  (Something that was mentioned above.)

Such an attribute doesn't affect me too much.  Aside from a couple of OLED phones, the display tech around me is all LCD.  I have two 27" IPS monitors in front of me now and the TV is a cheap Aldi 39" LCD.

The cheap TV is only Full HD - but that's pretty good enough to watch movies.  I've set up a PC to run into it mainly to use Kodi and that works pretty well.  (It's absolutely crap as a monitor.)  It does have a bit of light bleed, but not all that noticeable unless you watch space shows - but then I try and forget about that and just get into the story.

It does, however, have one trait that I find rather annoying ...

In images where there is a notable area of gradual shading change, there are very obvious steps.  It's like looking at a contour map overlaid on the image.  If there was ever an argument for going for a high bit count video decoder, this is it.  I sometimes wonder if it has an 8 bit decoder or a 6 bit!  I sometimes dream of something with 12 bit.

For the most part, these irritations are passing and by not getting hung up about them, I get to enjoy my media.

I have seen 8K.  I have seen OLED.  ... and I have seen the credits rolling on a dozen screens on display in a major electronics retailer.  The two Sony units were clearly identifiable - just by looking at the upward scrolling text.  On all the other units, the text movement was jittery - but on the Sony units, it was buttery smooth.

QD-OLED certainly has my attention as well, but I am a little hesitant about the ageing issue of OLEDs.  Yes, by having all the OLEDs the same colour, one issue of ageing is addressed - but they are still going to age.  Elements being driven at different intensities will cause different ageing - so burn-in is still on the cards.

I can appreciate ALL the things that various manufacturers can bring to the market - and I look forward to seeing where we go with it all.  BUT, I am not preoccupied with seeking the latest and greatest, shelling out more cash to watch material which - for the most part - makes little improvement in my life.



I held my 3 day old grandson for the first time yesterday.  That was worth more than any TV.

Depends how you define the "life" of the panel. Has it reached EoL when the overall brightness has fallen below some fraction of its original level, or when there are visible artefacts in the content (colour shifts, static logos and the like)?

Posterisation is very common with low end equipment for exactly this reason - insufficient bit depth.

It might be worth trying a different source component; this effect is noticeable on my TV when viewing Netflix using my cable provider's box (Virgin Tivo V6), but the same content is smooth using the Netflix apps on my BD player and PS5. The difference is simply that both of these are made to deliver a level of performance rather than being strictly built down to a price.

That's just default settings being different. Intermediate frame creation is a standard feature to help smooth motion; on movies, for example, some people prefer a screen that shows 24 frames/sec to exactly match the original source, others like to have the extra (interpolated) frames. Sounds like the Sony units may have this feature on by default, and others have it off, but either way, 30 seconds in the setup menu and you're sorted.

That buttery smooth is an image processing feature of the TV's chipset.  It is bs.  It is not the original film's 24fps.  Yes, apparently, there are those who like it, but, you are no longer seeing what the original film actually looks like but an interpreted process of what the chipset believes should be displayed inbetween and mistakes are usually made during high speed action sequences.

Note that you can turn the feature off in the Sony's by selecting the 'reference director's film mode', or whatever the industry calls it.  The director's mode also turns off the stupid auto-dynamic range BS making most movies look a lot darker, but now the daylight outdoor scenes will be properly bright without blooming in bright areas and dark or indoor filmed scenes will be properly dark.
Brumby:
The thing is (aside from the low bit depth) I only really notice this stuff when I'm actively looking for it.  I'm not going to shell out a fistful of cash chasing something that only bothers me rarely, if at all.

Anyway, most of my "screen time" is on the monitors before me as I type.....
