I have several monitors with different pixel sizes (that is, size of individual pixels; not resolution). This means that when I put them next to each other and move the mouse between them, it's not perfectly smooth.

I know that in Windows, you can move monitors up or down relative to each other; but is there a way to "scale" them? To say "They have the same pixel height, but this one is an inch taller"?

I think the term you are looking for is that the monitors have different PPI or pixel density values. –  sblair Sep 8 '11 at 23:14
    
If you have two 24" monitors at 1920 x 1200 - then they would both have the same "size of pixels" aka pixel density. If you had a 24" monitor and a 23" monitor at 1920 x 1200 - then the 23" would have a higher pixel density / smaller pixels. Are you working with 2 monitors with different sizes? –  Dustin G.

For display monitors, the pixel size is typically specified by the "dot pitch" number, usually in millimeters. Obviously the pixel density can be derived from this spec. The dot pitch is an important number in evaluating the quality of CRT displays, since it relates to the max resolvable resolution. –  sawdust Sep 8 '11 at 23:40

There is no way to do that in the default interface. Some third-party app might do that, but I'm not sure what such a setting would imply. (Would an app's window get resized as you moved it from monitor to monitor?) Maybe we'll get it when we get resolution independent operating systems and window managers.

Unfortunately, the solution right now appears to be to move the monitors to different distances from you so the pixels appear the same size.

@Synetech It's not fancy, but it works. –  CajunLuke Sep 9 '11 at 15:22

Different dpi for different monitors is possible from windows 8.1 but I don't know if it's applicable for win 8 too

But of course it's not perfect at first. A program open on which monitor will inherit that monitor's dpi. And when moving to another monitor it'll be scaled up/down depend on the dpi, so the result might be blurrier or sharpener
