k1114 :
Go to a store, look at 4k monitor vs 1080p monitor of the same size, then proceed to feel awful for making such an ill informed post.
Mk I have a MSI GAMING X 1070. I have a 27" 1080p 144hz, a 27" 4K 60hz monitor, & a 50" tv. I also have a friend who has a 4K tv & 1440p monitor, we've ran test hooking my computer up to it. So I'm official squashing this bull crap right now.
The bigger your screen the more the resolution of an image stretches those pixels in the picture across the screen. Assuming you always sit the recommended distance based off screen size from monitor & tv it is unoticable the difference between 1080p & 4K for most screen sizes.
So why buy 4K you ask?
Here's why someone sitting 3-7ft from a 27" 1440p monitor will notice no difference in image quality from a 4K monitor.
Someone sitting 3-7 feet from a 34" monitor would but that's way to close to your face for a monitor that big. So with monitors 1440p 28" is best you should get for realistic pc gaming.
On the TV front the larger your screen the easier it is to see things at further depths in gameplay. Like Tomb Raider 2013 trying to shoot guys far away with an arrow is significantly easier on a 78" over a 50" tv. But on a 78" tv 1080 is to far spread & looks pixelated. A perfect example of this play gears of war 1 on a 50" tv. So this is where resolution comes in to make up for the stretched picture. Now can someone tell the difference between 1080p 50" & 4K 78" besides easier to see from larger screen no they can't. Pretty much because it looks identical. The difference is negligible. 4K is meant to fill the pixels & large screen areas anyone who says they can see a difference is horse shit & trying to justify a retard main stream buy. My girlfriend has 24-22 vision & she confirmed all our test between 1080p/1440p/4k.
If you have a smaller screen even like 21" 1080p vs a 21" 1440p vs a 4k 21" there would be no noticeable difference unless your face was glued to the screen. Any difference you see is in quality of panel. Possible brand/ color accuracy upgrade.
We drew this conclusion by testing my 1080p 27" vs a 1440p 28" vs my 4k 27" on some games the 1080p had hardly noticeable jags mostly world of Warcraft. On all the battlefields it was very difficult to tell. But one thing that was consistent was literally 0 I mean 0 difference in an asus 1440p 28" & a asus 27" 4k.
My recommendations
Monitors:
1. 24" or lower 1080p
2. 25" or higher 1440p
3. Anything over 28" you might as well bought a tv and sat further way you'll be turning your head to much.
TV suggestions:
1. 720p console like Xbox 360 or Wii U don't pass 43" tv at 1080p
Nintendo NX,PS4,Xbone 1080p for anything 50" or under even 55" is subjective I'd say depends on user more at that point.
3. Anything over 55" go 4k upscale consoles & hook your pc up to it for enjoying controller support & steam big picture mode.
Oh one last thing we did an Nvidia Dsr 4k test on my 1080p 50" tv vs native 4k on his 78" for the sole purpose of testing higher resolution textures in bf1 & need for speed 4k textures. Also no difference it's like installing realism mod that's only available if you have 4k active dynamic or native.
Don't hate me just the messenger
