You're missing out on resolution (4K) and picture quality (HDR, contrast ratios, color gamut) improvements by doing this.
Not everyone suffers from FOMO.
I've only seen one movie that was worth the bother and expense of seeing it in 4K (Rear Window).
The rest of the things you mention are mostly for a very small slice of theoretical people with perfect vision in perfectly lit rooms at the perfect height and viewing angle.
Beyond icons on a sticker checklist, they mean nothing to the 99% of people who just want to watch sportsball or eat popcorn while watching Disney films with their kids.
You can put lipstick on a pig, but most people are still watching pigs.
Pretty sure I read this same comment when the transition from DVD to 1080p/Blu-ray occurred and people were updating their TVs.
The difference is the 4k content isn't available like the 1080p content was then. Streaming "4k" is a bad joke with its bitrates.
The OP is not asking for a TV to watch TV on, he's asking for a TV to use as a second monitor for his laptop. When it comes to computer interfaces, the difference between 4K and HD is enormous. Especially for text.
Rear Window? A movie from 1954? Can you explain how that was better in 4K when the footage isn't even 4K?
The footage is analog (on film). It was shot with 0 pixels, so 4k pixels on an edge doesn't matter. Side note, footage itself is a term derived from film (how many feet of film).
You can scan film into whatever digital resolution you want. You could do an 8k scan if you felt like it. You might run into issues where the resolving power of the film is less than the scan, but 4k is not an unreasonable resolution to pull out of well lit studio shot movie stock.
It was on film, probably 35mm. That film contains more information than 4k video. Resolution is between 4K and 6K.
Plus it’s a black & white movie, and b&w film has a higher “resolution” than color too right? Because you’re dealing with silver particles instead of physically larger color grains.
Or something like that. Someone more in the know please check my math.
It was shot in colour. But the rest of the comments in the tree apply.
It seems my memory fails me.
It's not in black and white.
If it was shot on film, isn't it possible to get 4K from it? Thought that was old news already.
