Description (last modified by diver)

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.

on this issue, the bigger issue is the lack of functioning displayport support. DisplayPort support is in progress... hopefully will be done before R1 betas
