Has anyone had any issues with multi-monitor rendering with directx on the ATi 3450 GPU?
I am seeing hresults S_OK for all my device creates and presents etc.
With the reference device I see Both screens rendered correctly in borderless window mode i.e. non-exclusive.
With the hardware device I see a single frame where both views show correctly on each monitor then on subsequent present calls only the primary monitor is shown the other screen is Black.
The interesting thing is Pix is showing both my screens rendered correctly from its viewer after I profiled the rendering every 6 frames. So I'm definitely drawing correctly I just don't understand why I would see the first frame correctly then output black subsequently.
I'm using directx 9.0c from the February 2005 SDK.
My next steps are to try the code on a friends pc with a different GPU and hope it works, If anyone has any ideas what I could do to track this tricky issue down I'd appreciate it.
Thanks in advance.
