I just got an Asus PA279Q (27") and cannot get it to work with my late 2012 13" Macbook Pro. I've connected the mini-DisplayPort to the Thunderbolt connection on my MB and plugged the other into the monitor. When I turn the monitor on, I get a splash screen and then a message that there's no DVI signal. The resolution on my MB changes, as if it senses the PA279Q, but then it reverts to the previous resolution. I do the same thing going HDMI to HDMI, and get the same result. I've tried the patch-edid.rb script, and it's still the same. It would be nice if ASUS had some troubleshooting suggestions, but I haven't been able to find any. Thanks!
