HiNo. Its a passive (no active electronics) device that is only DVI single-link:
"resolutions up to 1920*1200@60Hz"
30" displays need DVI dual-link to get their higher resolution, and that means an active, powered adapter.
They usually have a USB-A plug to plug in to power them.
This is what Apple originally sold:
Mini DisplayPort to Dual-Link DVI Adapter
Mini DisplayPort to Dual-Link DVI Adapter lets you connect the 30-inch Apple Cinema Display HD to a Mac.www.apple.com
You will need a dual-link DVI adapter, not single-link.Hi
Yes I have that cable and I thought it would be that which would then plug into the adapter I have mentioned?
