I am a relatively new After Effects user. I am currently working with a 24" Gateway monitor using native resolution of 1920 x 1200. I love After Effects, but I am having a tough time with the tiny font size of the GUI (at least for my aging eyes). I understand that the font size of the GUI is not adjustable, so I am considering upgrading my monitor. My question is this, will the GUI font appear noticeably larger if I move up to a 27 inch or 30 inch monitor (i.e. Dell Ultrasharp at 2560 x 1440 for the 27" model or 2560 x 1600 for the 30" model) that runs at a higher native resolution? What monitor size and/or native resolution would you recommend for someone that is having trouble with the tiny GUI font?
A larger monitor at a higher resolution will provide more desktop space but not bigger text on the GUI. You can get a bigger size monitor but use it a a lower resolution (e.g. 30" at 1920x1080). What I would recommend is getting a second monitor to use with your existing one. This way you can have your comp window at the highest resolution on one monitor and the rest of the interface on a lower resolution on the other monitor.
