Mac Mini does not wake Cintiq

For 2 years, I used a Cintiq 21UX as the main monitor with a 2009 Mac Mini. It was connected with a mini displayport to DVI-I adapter and worked perfectly.


I replaced the Mac with a new i7 with the same setup (the mini displayport plugs into the thunderbolt port). When I boot the system or wake it from sleep, the image does not appear on the screen. The Cintiq's status light turns blue for a few second (its ON setting) then turns amber (its SLEEP setting). I have to unplug it and plug it back in to get the image to display.


I updated to the latest Wacom driver, reset the PRAM and SMC, but the problem persists.

Mac Pro (Mid 2010), Mac OS X (10.6.8)

Update: The same problem happens with a different monitor and the same MDP to DVI adaptor.


So my best guess is that the problem is either with the adaptor or with the Thunderbolt port itself. I ordered a new adapter to test.


Meanwhile, I'm using the HDMI to DVI-D adapter that came with the Mini, along with a DVI-D to DVI-I adapter and that works fine. But that's a workaround and does not resolve my original problem.

Out of curiosity, I compared the tech specs for both Macs, under Graphics and video support.

There's no mention for or against using a Mini-DVI to DVI Adapter in the 2011 model. But OWC lists its adapter as compatible with the 2011 model. http://eshop.macsales.com/item/Newer%20Technology/CBLMDPDVI/
