Description (last modified by )
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 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.
