HelloI cant get FSX to use multiples monitors in full screen when FSX is in DirectX 10 preview mode. When I undock my windows, move them to the secondary monitor and swtich to full screen; the main view is there on the primary monitor but secondary monitor doesnt show anything and I permanently get the hours glass icon. I have to shutdown FSX.When I disable the directx 10 mode, I can use multi monitor perfectly in fullscreen mode.My system is running Vista x64 ultimate and a nVidia 8800gt.I have tried multiple version of the nvidia drivers, from 169.25 up to 174.12. No change. The Vista OS hotfix for multi monitor (mentionned in PTaylor's blog) is installed.Is it another issue with the nVidia drivers or multi monitor simply doesnt work in DirectX 10?thanks!

I have had the same problem. It seems to work in DX 9, but not DX 10.

Unfortunately, it's called DX10 Preview for a reason. FSX's implementation of DX10 is not complete....hence the term PREVIEW.

Well, I understand the preview thing but after some more testing with a friend who has an ATI video card; multi monitor works in full screen and directx 10 preview on his system.the only other thing different between his system and mine is Vista 32bits (his) vs. Vista 64bits (mine).So my guess is the issue is either with the nvidia drivers (I wouldnt be surprised) or in Vista x64.
