I'm running my display at 2560x1600 and I have an issue with poser; some of the interface text (i.e. ANIMATION PALETTE) is unreadable at that resolution. 

I used to have a matrox display card that had this awesome pixel touch feature that was a hardware zoom.  It was great for doing a quick zoom in/out, but the parhelia is the last card I believe they've developed for mainstream use.

So I just downloaded a demo of ZoomText - it allows me to zoom on-the-fly in and out of the entire screen..  I like it better than the default windows magnifier, which has a magnifier window that gets in the way of the interface:  With ZoomText, the entire screen just zooms in,...

ZoomText is not quite as fast as the Matrox HW zoom, but I can use the CTRL + mousewheel to zoom into those hard-to-read areas.

One caveat is that it doesn't work with opengl, but it does work with SreeD.  There may be a better alternative, I dunno.

Just FYI for all of you running at insane screen resolutions

Peace,

There is a zoom tool built right into Windows (under Start:All Programs:Accessories:Accessibility:Magnifier).  You can copy-paste the icon to your desktop for quick access.

I don't remember if this affected Poser font display at all, but you can also set the general font display size in the Display:Settings:Advanced properties under General:DPI.
