34" 1440p vs 27" 1080p?

[Blackout65]

I was wondering what would give the best quality a
-34inch
3440x1440p

-27inch
2560x1080p or 1920x1080p
Or 27" 2560x1440p or 1920x1440p

This is for watching anime and shows. I don't really care about the black bars. Thank you.

depends on what you mean by "quality"

do you want lots of pixels -- high rez? Then get the 3440x1440 screen.
do you want a high pixel density -- aka 'retina'? Then you want smaller size, and higher rez (none of the screens you listed fit that)
do you want accurate color? That depends on the manufacturer of the monitor
do you want fast response time? That also depends on the manufacturer of the monitor.

MY preference is for 2560x1440 @ 27"
I would skip a any 27" screens still running 1920x1080. that makes for a grainy picture

I don't really get the difference between resolution and pixel density but its along those lines I believe. I want the video to look crisp and clear.
When I was watching anime on my s7 edge compared to my monitor (1600x900) it looked so much better on my phone. I don't know if its because of pixel density or resolution.

23"-24" then go 1080p
27" then go 1440p

s7 edge is both. That is why it looks so much better.

Based on your post - your after "pixel density" so you want higher rez in a smaller monitor size which gives you more 'pixels per inch' the more pixels per inch, the clearer the picture will look.

to get pixels per inch, divide screen width by the horizontal resolution. you can get the screen width off the manufactures site. Horizontal resolution is the first number for monitor resolution. For a 24" monitor its 22.5 inches wide. so 1920 / 22.5 = 85.3 pixels per inch (PPI)

some numbers to look at:
a 24" monitor running at 1920x1080 -> 85 ppi
a 27" monitor running at 1920x1080 -> 76 ppi
a 27" monitor running at 2560x1440 -> 101 ppi
a 32" monitor running at 3840x2160 -> 131 ppi
a 27" monitor running at 3840x2160 -> 152 ppi

The Apple "retina display" tag is greater than 200 pixels per inch

I got the monitor dimensions off NEC's website (www.necdisplay.com)
