same screen size different resolutions

[qwertywarrior]

i wanted to google this but what came up was different (same screen size different resolution)

 

 

anyways

my 1600p dell i bought in 2006 feels like it will die soon because im getting weird glitches like 10 times a day ( still works perfectly though)  but im pretty sure it wont live to 2015

 

what i like to know is this

here is an example

 

 

 

 

would a 27 inch 2560x1440p display look just as good as a 27 inch 1920x1080 screen if they were both set to 1080p (playing games) ?

 

i remember Linus talking about this when he said a UHD monitor will look great showing 1080p because its 4 times greater

 

but what about something in between like a 1440p monitor playing games at 1080p ?

 

also i cant remember the term used when talking about "it" . i vaguely remember Linus using a word

 

 

 

 

thanks

The problem with 1440p to 1080p is that the pixels won't be square as they will with1080p -> 2160p because it's not an increase in a magnitude of 2.

i think the word linus used was interpolation

thanks for the input

1080p plays perfectly on UHD because UHD has exactly double the height and double the width.  So if you play 1080p content, you are displaying 1920 horizontal dots from the content on a screen with 3840 pixels.  Each dot takes up exactly two pixels, and the same in the vertical direction, so the content can be displayed exactly as it is supposed to.

 

If you are playing on a 2560x1440 monitor, you are displaying 1920 horizontal dots from the content over 2560 pixels.  Each dot from the original content takes up 1 and 1/3 pixels on the screen.  Of course you can't have the dot displayed on 1 and 1/3 pixels and have the other 2/3 of the pixel displaying another color, a pixel can only be one color at a time.  So the display controller does something called interpolation where the pixels just show the color halfway inbetween (well, the algorithm is more complex than that, but that's the basic idea).  For example if a pixel needs to display 1/2 white and 1/2 black because the original content doesn't line up evenly, it would display grey.  This leads to fuzziness and blurry text along with everything else, when not using native resolution.

i guess when my 1600p monitor dies  i just hope there is a variable refresh rate IPS monitor at 1600p/1440p available

4k will be too hard to run in the coming years

so will linus vids (in 1080p) look bad on a 2560x1440p monitor? because im planning on buying the rog swift(still deciding) and ive only had experince with 1080p.
