50 inch 8-10k 4k mm TV buying advice

Hello people!

Finally, I address you on air as usual when I have finished my genealogical research on the same topic that I find relevant at the moment…

At the moment, it's a bedroom TV and that's where I'll be spending my time as the other three people in the house have to watch Gekås and Dubai Blind every evening for a few hours while I then go around fixing leaky garage roofs at home. evening. but! When I do get time to sit down, I like to watch a really good episode of a random series or a leftover episode of some action, so to speak, with the whiskey reaching its peak. This amount will then be spent in our bedroom on a 50-inch TV (max. 116 cm).

What I've come to realize is that blackness is the most important thing so that Nick Fury's beautiful face doesn't catch on with the rest of those around him. So I can also be sensitive to image lag from the old FPS era (the 30 year period when you had reflexes and weren't detected for a week because you turned off the bedside table lamp).
So maybe Blooming won't be so bad as Nick can have sweet little Gloria (the religious Polish gene lives deep inside me)… I just see it in the picture.

A brief summary of things I might be overthinking or focusing on, so to speak:
Full backlight – OLED/QLED
ARC-HDMI (at least one port is probably the standard today)
4K
Maximum width 116cm aka 50 inches

The models I'm looking at right now are these, but if you have something to suggest or have input that says “Hey! I forgot this very important thing” feel free to write it down because there's nothing worse than being owned by Elmutant in the shop and coming home with a polished piece Of shit. The budget is from 8 to 10 thousand

Considering this despite going over budget but only getting what I want and a clearance discount (is that bullshit?)

I feel like these two are pretty low on the choices when it comes to options… Have I slacked on the relative science?

Thank you for reading our alcohol forum post!
