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  The supported video cards listed on Apple's website is outdated - you can't find them anymore.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.

Thanks.

Hi.

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 hope you look at my comment as well since I posted the USB 2 alternative straight up.

Since the card has dms-59, your solution would not work for me Merete.  Regardless, the card doesn't support dual link dvi as robo stated in his post.

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 :)

Hi,

http://uk.insight.com/en-gb/productinfo/graphics-cards/HPOGQK638A

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?

1900x1200 is actually fine fortunately.  That's the res my customer was using before.
Rob Knight

Hi,

I believe it states it here:

http://support.apple.com/kb/HT3571

Maximum resolution with single-link DVI is 1280 x 800 - the dual-link card should do the job for you.
