As my video production tasks become more and more involved, I have decided to pick up an external monitor for my 2.53 i5 MBP. I was considering the 20'" ACD, but then I realized that 1080p was a no-go. So as far as I can tell the 23" is capable of 1080p. Is anyone using a 23" ACD with a newer MBP via mini displayport to DVI? Are there any problems with this setup?
