[Brian Wells]"If I were to make a short video in AE and PP, 1920x1080, would it be better to get a 27 inch monitor that is 1920x1080? or one that has a higher resolution?"
I like hi-res monitors. A 2560x1600 (or 2560x1440) monitor has room for an entire 1920x1080 comp viewer plus other panels, like the timeline, effects controls, etc.
[Brian Wells]"Will the higher res somehow be a negative?"
If you increase resolution but leave the physical size the same, the pixels themselves become smaller. That means some of the UI elements can get pretty small on-screen.

I sort of see your point. I was thinking though when I do a full screen preview in AE the with a 1920x1080, since output is 1920 by 1080,(I am planning to set the Res in AE to 1920x1080 output,renders whatever) each pixel will match nice and evenly, with a 1920 by 1080 monitor. Or doesn't it work that way?? sell me your idea please Walter, or anyone else that want to chime in
