I am here mainly to talk about something that i have thought about in the past, but have never seen or hear about from anyone else, ether that or they were not being direct about it, maybe this will give people a good perspective on displays and their choices when buying them in the future.
(i don't have charts, diagrams, images, im sorry that this post is going to be basic)

Display size to resolution ratio?, pixel size is, to me, very important, for me, it is the different between full HD and 4k, let me explain...

First, i would like to say that each resolution has a set amount of pixels, 1920x1080 = 2,073,600 little squares displaying a color within a given screen size, this means if you have to choose between a 50" TV and an 100" TV, that are both 4K, the 50" screen will display better quality, but!, there is also how close/far you sit from the display, and! how small the pixels are to begin with, lets base this on a minimum 25" display size and max, 100" display, sure the pixels on the 100" display will be 4x bigger then the pixels on the 25" display, but the amount of pixels on a 4K display is, 3840x2160 = 8,294,400, that's a lot, the 4x difference in pixel size may not make a visible difference, depending on how close/far you view the display, this being said, if you view a 1920 by 1080 50" tv from far enough away, the pixels(if visible, lol) would seem the same as the pixels on a 1920 by 1080 25" tv, but the 25" tv would be a display that you could sit closer to at that resolution, without noticeable pixels, an extreme example would be a 1000" display with 1920 by 1080 resolution, up close those pixels might just be the size of your thumb!, you may not even be able to tell what you are looking at lol, but given the screen size, you could slowly look up towards the top of the display and notice the image clearer, the farther away those top pixels are, giving you a great perspective on how a bigger is not always better, big screen, low pixel count = 🙁 empty wallet(simply put), so if you want a high resolution monitor or TV, or big display with high quality image, here are some examples...

[Edit01} changed resolution/display size examples to consider scaling issues with high res on smaller displays(Credit goes to "feelinfroggy777" for bringing it to my attention), now giving that scaling(up) can be an issue with smaller screens, i believe that scaling down can have a similar issue, so ive added "sweet spot" to the example as to address that as well, now with minimum to max display sizes for each well known resolution.
(if up scaling becomes better in the future, the minimums may no longer matter, same could be said about scaling for bigger displays)

Monitor Sweet spot(computer, closer sitting)
Full HD: 24" to 28"(best guess)
2K: 28" to 32"(best guess)
4K: 34" to 45"(max is best guess)
..8K: 45" to 55"(best guess, that's a big monitor lol)

(I assume TVs have better scaling as TVs tend to be well liked at larger sizes, but more sold at mid size Full HD 40" to 60" best guess)
TV Sweet spot(living room, farther sitting)
Full HD: 40" to 55"(best guess)
2K: 45" to 65"(best guess)
4K: 50" to 75"(best guess)
..8K: 60" to 90"(best guess)


Now i should point out that i am no expert, and that these are examples and not exact numbers, so keep that in mind, i may be wrong about some things and i may have missed some information, this is merely a discussion with the hope that people will start thinking about their buys before regretting them, if there is anything! incorrect or if there is something i have said that has nothing to do with what i was trying to talk about, then feel free to correct me and let everyone that reads this know about it, i will even correct this and credit you. thanks.
 


ok good, but how does that help?, explain, as this is a discussion, let's discuss, oh and nice 5GHz CPU btw.
 
ppi is best way to measure what you need I found that once you get near or over 100 PPI the picture is much better also if your PPI is over 100 you can actually turn off aal because you wont notice any difference and be able to maintain your 60 fps a lot easier
 


cool, good to know, i will be looking into this, thanks
 


There is a downfall the pixel density. If your PPI is too low, (high res on a small monitor) then the scaling is very poor and any desktop uses for the PC become all but useless. For example, running a 4k res on a 24" panel is very hard to perform basic PC functions and effects the size of text and HUD in games. Even a 4k, 27" monitor is a chore to use. Windows 10 scaling is terrible as well as it will affect some of my games so I keep it off all together.

I have a Predator xb32 which is a 4k, gsync, 60hz, IPS, 32" panel and it is probably as small as I would go at 4k resolution. I think 1440p is the sweet spot for gaming and basic desktop operations. This is why as my primary monitor I use a Predator x34 which is a 34", 1440p, 100hz. It is an amazing monitor and is great for every task.
 


now that is something i did not think about, ill add it to the top, but if i can get a minimum monitor size for 1440p as a recommendation from you, then i can add that as well, along with credits to you.
