#8485 new bug

Radeon HD 6770 - driver now works, but second display remains black. — at Initial Version

I have a Radeon HD 6770 card. And two high-res (1920x1200) monitors attached. #1 is Displayport. #2 is DVI. The build I tested with is Haiku Nightly GCC4-Hybrid (hrev44063).

First - I am happy that the Radeon drivers finally work with the HD6770 card. However - it only displays on the DVI connected monitor. The DisplayPort monitor remains Black. To be clear - when I have both monitors connected, only the DVI monitor lights up.

With older Radeon Cards (and even when using the VESA drivers) - both monitors would light up with the same image. This is the default behaviour I have seen with other OS's as well.

I know that Haiku does not yet support multiple displays, but the behaviour I have seen previously in haiku, and my 'reasonable expectation', is that all monitors should light up.
