Video adapter for Apple Cinema HD 30" display
I have a user who had to replace her computer. The video adapter is an ATI Radeon HD 6350 in a Dell Optiplex 790 running Win7. The connector on the back of the card is one of those DVI where it's all pins and used to connect a DVI splitter cable for dual output. Each of the outputs from the splitter cable is a DVI-I Dual Link and the connector for the Apple display is DVI-D dual Link. I can't go above 1220x800 (or something to that effect). I have the most recent drivers from ATi installed.
I believe it's because I need a video card with DVI-I dual link connector on the card itself but I'm not sure. The supported video cards listed on Apple's website is outdated - you can't find them anymore. I can't pull the video card out of the old system because it's AGP and the new system has only PCI slots.
I'm looking for a fix or a video card that can be purchased that will support this display.
The HD64350 with the DBS-59 connector to the Dual DVI-I (dual link) adapter so I don't think you need the connector on the card itself.
Is the DVI-DVI cable you're using supporting Dual-Link? Dual-link uses additional connectors in the socket to provide the higher resolution support - perhaps try some different DVI-I cables if you have them?
Is the Apple display being detected correctly or just as a LCD display? You might want to install the driver or use a generic driver supporting the resolution?
Device Manager, Monitors - Generic PNP Display, Update Video Driver, Browse My Computer, Let Me Pick, Untick Show Compatible Hardware, Standard Monitor Types, Digital Flat Panel (1920 x 1080).
Then click Next and Close.
You might also want to launch ATI Catalyst Control/AMD Fusion and go to:
Desktop and Displays, then select properties of the monitor - it should show you the maximum reported resolution, but you can overrride this if you need to.
I'm sorry, I should have elaborated. The card in question actually does not have Dual DVI support even though it comes with a dual DVI cable (it's a single port card that has a 2 DVI splitter cable that allows to monitors to be connected). The connector on the card is a DMS-59 which I believe is the source problem.
I'm bringing out another card next week to see if that's the problem.
I appreciate the effort Merete - I'll be sure to spread the 'love' accordingly :)
Looks like the maximum resolution of the DVI is 1900 x 1200 - I would have expected the Apple display to go above what it is doing but maybe it's that 'incompatibility' in the ealrier post?
