I plan to buy a 4k 28" screen in order to replace my dual full-hd screen.

The main reason for this is to have "more screens" in front of me. I plan to use it like if I had 4 full hd screens in front of me, meaning I will have 4 various applications opened at the same time and visible.

I know that in theory, it would be possible but before purchasing it, I'd like to be sure that in practice, this is something really feasible and enjoyable to have ; not having quircks, bad pixels, or anything like this.

That's the reason for my question, I'm turning to those owner of 4K screens to know if what I want to do is possible or not.

(Note: I plan to take a 28" instead of a 24" (like Dell's) for the same reason : having enough visual space to place the equivalent of 4 full hd screens. I'm afraid a 24" would be too small).

Thank you in advance.

Sure, though it would be like having 4 tiny screens. I use windows and its lovely snapping function to do this but its entirely usable. I do note you're missing a few essential factors.

Higher resolution does not mean 'more space'. To use my 4K 27 and 28 inch displays effectively, I end up having to use display scaling (so text is at 150% magnification - text is smaller than a 1080p screen but not that much) so I don't really have '4x' the screen space, maybe twice. Also, I find context switching isn't that easy, and I can't really use more than 2-3 windows at a time unless I have a second window opened up for research on something I am working on. Not sure how fedora handles these things.

It is readable, and usable though. The weak spot here is probably my concentration span.

You do want a 27ish inch screen though for 4K - my other answer here goes into that - essentially that's the optimum size for most folks using a desktop with a screen 150cm away. Higher resolutions give you sharpness. Text is glorious (and tiny, and needs to be scaled up for many people). That isn't magically going to translate to 'more' screen space, beyond a point.

I have a pair of them, and even a single screen paired up with a lesser screen was pretty fantastic.
