I decided to "go big" and grab a 30" ACD to replace my 2 20" displays. I wanted 2 23's, but their color and quality is so iffy it would be about impossible to find 2 good specimens... Anyway, I missed dual screen, because its nice to have a secondary display for pallettes and such. The 30" and a 20", both at 16x9, is just too wide to use reasonably. However, fellow forum poster "blakespot" inspired me with his 30" ACD and HP 1600x1200 display mounted in portrait mode. What if I could make an adapter bracket that would allow the 20" to sit, in portrait, on my desk? 2 Hours with my Mitutoyo calipers and Solidworks 2006, and a trip to a machine shop.... The bracket is milled aluminum, and has mounting points to emulate the back of the Apple ACD, and then 4x100 MM slots to mount to the Apple VESA adapter. I used slots so I had a little adjustability so the top of the screen on the 20" would line up with the top of the 30" screen. With the help my girlfriend patiently holding the screen when I took measurements, we determined it worked better to have the viewing area lined up between screens rather than bezels. It actually works out well, the 20" ACD "top" is where the radius on the 30" begins. Wonder if there is some secret Ives calculation in these bezel designs!
