Zoom 100% - 1:1
In print and web documents the 100% zoom isn't acual an 1:1-size (800 pixels are not shown as 800 pixels, 20 mm are not shown as 20 mm).
I reconize that it depends on your Screensize/and os dpi settings, but that must be possibe! In Acrobat i am able to set an customize resolution (for mm) and in photoshop 800 pixel are 800 pixel at 100% zoom.
Agree and if Adobe would make a setting in the Preferences where you can input your monitor inch this must be possible.
