Hey all.
Something very strange happened to me. My Cintiq 21UX will not be detected as a monitor by my Late 2013 Mac pro.
Everything works just fine on its own, My MacPro outputs signals to other monitors via thunderbolt and HDMI with no issues, My Cintiq 21UX Receives Input from my other Macbook Laptop with no issues. My MacPro detects My other Cintiq 13HD just fine via thunderbolt or HDMI. I tried EVERYTHING. Updated wacom drivers, Used Old Wacom drivers. Updated my OS, reformatted my computer, Got new adapters, Reset PRAM, Reset SMC. OH and the tablet part of the Cintiq Works perfectly on the MacPro, just not the monitor. Cant find anyone with this issue online, it's been weeks and is really frustrating. It seems that just the combination of my MacPro and My 21UX is what doesn't work.

How are you connecting the Cintiq to your Mac exactly. From what you describe the issue is most likely in the adapter.
