I managed to see my first (as far as I know/remember) 8k TV today, at a shop. It was around 65", and a very high price, possibly £3,500 or some other high price.
The picture did look good (I'd prefer to change the screen to show various real life signal sources, rather than their 'special' video clip, which could be 'tuned', to make the TV look good, and not show up its defects).
As mentioned before in this thread, the rather large size 65" (they had 75" on show, I think, and 85" were mentioned, as existing, within the shop label(s), possibly for ordering direct to your home).
But, up close (near, nose touching screen, close), I could apparently see the individual pixels, quite easily, But far back, it did look good.
But the massive OLED TVs (probably 4k), had an as good, or better display. At least on the very limited indeed, video, they kept on playing back, at that shop.
In truth (not that I'm lying here), even the £499 bread and butter, LCD/LED, 55" TVs, seemed to have very good, nice/big pictures.
If I was buying a TV currently (I'm NOT), I suspect I'd look more closely at the QLED ones, as although they don't have as good a picture quality as the OLEDs, it is still pretty good. But with much less chance of screen burn/retention issues/worries.
Although I agree we need to reduce our (worldwide) power consumption and hence CO2 footprint. I DON'T like the idea of a big organization (e.g. the EU), choosing a lowish upper limit, on my behalf. Forcing potentially nicer/better TV options, to be unavailable.
They sort of can't now, since UK/Brexit, but in practice, often can. Either because the UK follows suit, with similar laws and regulations and/or the higher power things, sales/market drops too much (as they can't be sold in the EU), so companies, don't bother making special versions, just for the (relatively much smaller), UK.
In other words. I'd prefer the powers to be, to ask us (users), NICELY (through advertising, public information campaigns, slight extra taxes/VAT on power hungry inefficient items and/or tax rate reduction on more power efficient items, and many other initiatives), if we can reduce our power consumption, have more solar power, increase electric vehicle and/or public transport use, etc.
Rather than making (in my opinion), pesky new laws.
Otherwise things could start getting silly. E.g. (hypothetical, completely made up, new rules) Powerful gaming graphics cards could be outlawed, because the EU suddenly says all new PCs, must use less than 50 watts, at max power use.
Similarly, many core CPUs, for home use, could effectively be outlawed, if such regulations were put in.
So I hope this EU laws situation is NOT the start of a thin-wedge.
