The new 20" works with all the other nVidea cards and ATI Radeon 7500, 9000 Pro, 9700 Pro. From the 20" Apple Web Page: "The Apple Cinema Display requires Mac OS X v10.2 or later, and one of the following systems: Power Mac G4 with an NVIDIA GeForce2 MX, GeForce3, GeForce4 MX, or GeForce4 Titanium graphics card or ATI Radeon 7500, 9000 Pro, or 9700 Pro graphics card" 32MB TwinView Apple OEM Radeon 7500 fits in Cube and runs 24/7 without a fan. I still have a few left for sale remember. E-mail me off list if you need one. I have happy buyers who can report prompt delivery and that it works as advertised. My most recent customer just fired up his new 23" Cinema HD and reports it works perfectly still with no fan in his Cube. "Thubten, Received the Twinview today, installed it in the Cube without the fence as suggested, connected the new 23" Apple Cinema Display ADC connector, booted up, installed the new Apple Display software that came with the monitor, and the monitor sprung to life in full living color. The Cube and the 23" ACD are one magnificent combination. Thanks for supplying the Twinview promptly to my doorstep." k On Friday, January 31, 2003, at 12:36 PM, Rob In der Maur wrote: > ... according to http://docs.info.apple.com/article.html?artnum=58692 > (see note 7). > > cheers > Rob
