I'm wondering has anyone come across any after market multi input adapters or expanders. A device or product similar to "Green Box" but has a Dual-link DVI capabilities with built -in A/D converters; which could be attach between the Apple Cinema Display 30 and the MacPro allowing users to use the display for alternative devices, video sources (Tuner/TiVo/DVR/PVR/DVD/BluRay) or any other sources (consoles) etc. I know there are displays with multiple inputs like the Dell 3008WFP but users like me, whom already have existing ACD might find this device useful. I've seen boxes like this but they don't support Dual Link DVI. If anyone has suggests, please give product links too... Thanks.
