New description:
I have a Radeon HD 6770 card.[[BR]]
And two high-res (1920x1200) monitors attached.[[BR]]
!#1 is Displayport.[[BR]]
!#2 is DVI. [[BR]]
The build I tested with is Haiku Nightly GCC4-Hybrid (r44063).
First - I am happy that the Radeon drivers finally work with the HD6770
card.[[BR]]
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 behavior I have seen with other OS's as well.
I know that Haiku does not yet support multiple displays, but the behavior
I have seen previously in haiku, and my 'reasonable expectation', is that
all monitors should light up.
