Are you sure those displays have everything needed for a smooth TV experience? Do they have eARC to connect a sound bar, and stuff like that? Modern TVs are also quite good at upscaling 1080/720p content, screens often aren't.
(I don't care about integrated speakers though)
1080 (even 720 really) is absolutely fine at normal viewing distances for most streaming content.
If you're a videophile you might care. Most people would not notice.
