I have hooked up my graphics card via akitio thunderbolt chassis . I have installed all the drivers necessary and still do not any image from HDMI out on card. The computer read my graphics card in that sections of system report before but now does not say it. I have downloaded CUDA and installed script for drivers and no image. Can anyone please help ?

Been lurking for a while. I wanted to share some of my experience with the AKiTiO enclosure. I am specifically trying to make AMD cards work with Yosemite, as I have a Iris Pro only mid 2014 rMBP, and cannot get external displays working with my GTX 750Ti... I have only been able to get a couple of cards to work (Microcenter is starting to get tired of me exchanging cards every other day.). Finally, decided I am going to fight to get the R9 280X to work with Yosemite, even though it's larger and more expensive than I originally wanted. While I;m having trouble with Yosemite, I decided I would try Win8.1/BootCamp and see if at least the hardware worked. First I bought a larger 10A(120W) power brick, did the tape trick and soldered power to the PCIe slot to support 75W to the slot. I used a Corsair CS650M ATX power supply for the 6 and 8 pin power to the XFX R9 280X DD 3GB card. Not wanting to mess with the enclosure yet (in hopes someone will figure out the nvidia output on the iris pro rMBP), I have the PCB naked on my desk. First boots into windows, were ok at the desktop, but unique heaven at anything above 1280x720, or using full-screen caused failure (blinking screens, crashes, or snowy)... I thought maybe it was the two different power supplies, I went ahead and soldered 2 x 18g yellow and black wires to the CPU 8pin connector on the Corsair ATX PS. Making the ATiKiO completely running off of the Corsair PSU. Immediately saw improvement in Windows 8.1, boots perfectly, and runs Heaven at full screen @1080p, with HIGH settings, and 2X AA, it ran smoothly and perfectly. AVG FPS was somewhere around 50FPS (can't remember off the top). So the dual power supplies were causing some instability. Now if I can figure out how to get Yosemite to boot fully with the IOPCITunnelCompatible injected into kexts, I would be happy... Thanks for all the insights here, especially goalgue, Tech Inferno Fan, mvc -- Thanks!
