Two screens, D3DERR_DEVICELOST, TestCooperativeLevel

jensmose — Wed, 25 Feb 2009 08:53:16 GMT

I make a windowed DirectX application, DirectX version 9.0c, on a system with a Intel GME 965 chipset, Intel Embedded Driver version 9.0 build 1203. I run Windows XP.
Now I want to use extended desktop with 2 screens. If I extend my desktop while I run my application I get a
D3DERR_DEVICELOST after Preset. When I then use TestCooperativeLevel I keep getting D3DERR_DEVICELOST.
I never responds D3DERR_DEVICENOTRESET so I can reset the device.
Does someone have an idea of what I do wrong.

which display are you trying to use?
xp will only let you render the the primary display when you are in extended desktop

I want to make a copy of the image that I show on the primary screen in a new window on the secondary screen.
I can do that if I make two swap chains on the same device or if I make two devices.
It works fine in either way. What is fastest depend on the system.

But want I wonder is why I never get a device lost when the desktop is extended.
I have to close the device completely and make a new device.
