Cintiq 24HD as third monitor
Hello,
I am new to the forums, and would like some help.
My set up is as follows:
2010 Mac Pro 2x2.4 Quad-Core Intel Xeon - Running Lion
12GB 1066 MHz DDR3
2TB HD
ATI Radeon HD 5770 1024 MB Graphics
Displays:
27" LED Cinema Display
24" Acer HD Monitor (HDMI - Minidisplay port connector)
Cintiq 24HD (Monitor Tablet)
----------------------
Now the problem!!
I recently purchased the Cintiq 24HD in hopes it could be used as a third monitor for my studio. I was told it should work directly, and just to plug it into the computer next to the two minidisplay ports and it should work. but when all three are connected, the Cintiq won't recognize. I can only switch between the cintiq and my second monitor by unplugging the Acer HDMI connector, but i want to use all three at once and it won't let me. Supposedly the HD5770 is powerful enough to support these three monitors / tablet.... Could anyone shed any light on the situation? Do I need to buy a seperate adapter? Please help!!! Thanks.
