Jannomag Posted July 19, 2009 Share Posted July 19, 2009 Hi, my Driver for my ATi HD4870 1GB on 10.5.6 iDeneb works perfectly. But I have two monitors and I can't use Dual View on OSX. In the preferences OSX shows only my first Monitor, not my second. How can I use both Monitors?

surrealillusion Posted August 6, 2009 Share Posted August 6, 2009 I've gotten a 4870 (sapphire non-reference board) to work with a DVI connected to port 1 and a DVI > vga connected to port 2 using netkas's solution. Both monitors show up and display at optimal resolutions with full QE/CI.

surrealillusion Posted August 7, 2009 Share Posted August 7, 2009 the physical ports on my card are dual-DVI. From there I use a DVI > vga adapter and a DVI = DVI connection. It was working with 10.5.7 using netkas's fix. I've been battling with trying to get sleep to function properly on my board so I haven't tested dual display in 10.5.8 yet due to multiple re-installs.
