You don’t want to do this with an OLED TV though.
One more reason for me to cherish my 2011 plasma TV. Also, it has none of that smart-tv non-sense, which is a big plus.
Of course, if your new TV is using 25W in standby, it doesn't really matter, but I am assuming something reasonable here.
My experience, having now bought several used plasmas from about that era, is that they tend to have extremely bright black points, comparable to a ~2015 mid-tier LCD screen. Fairly cheap modern LCDs seem to have superior image quality with sharper pixels as well.
Is this not your experience? Have I just been unlucky and purchased some aging panels? When I got into the market, I was of the impression that plasmas were renowned for their high contrast ratios, but I have been less than impressed.
Burn-in is extremely severe as well.
I personally don't like the "sharpness", I like the image to be more "fluid", with the colours more easily "blending in" into one another (don't know what's the exact technical term for that).
A few days ago I watched a movie at one of my friends' place, she has a fairly recent LCD screen. I couldn't shake off the feeling of "being in the same room" with the actors, there was almost no "cinematography" involved anymore. I didn't like that, made it quite difficult for me to raise that fourth wall. I know of the HDR on-off setting thingie, but I don't think it was only because of that.
I agree with the burning in, only that in my case is not that severe, for what it's worth. There's some of it in the upper-left corner, from when I used to leave the TV open almost non-stop to a shitty music channel, that music channel's logo has left its mark in there. It doesn't "show up" all the time, only when the screen up there is all "white"/light up, and only at times, not always. Either way, manageable.
that was most likely motion smoothing. for reasons unknown to anyone but TV OEMs it's enabled by default.
I'd say you're missing out at this point IF you consume media regularly, especially movies. Otherwise you probably don't mind much.
The pixel refresh thing doesn't seem to make any scientific sense to me as a layperson.
