From: driver_guy on 16 Sep 2010 13:12 Hi, I need a help for the scenario below: ================================ I have two displays - CRTC and DVI output. the crtc is the primary display. Now I want to change and try to tell Win 7 to switch to DVI as primary after reboot. How can I do in the driver? It seems on Vista, the DXgk call recommendVidPnTopology can do it. But in WIn 7, this DDI is removed. In IsSupportedVidPn, I can fail the original VidPN (Crtc). And I can let the OS shows desktop on DVI. But when I try to switch to crtc from desktop property page, I got unable save display settings error message. =============================== Any expert can help me? Thanks in advance. -- KC
