I recently discovered this thing: My cab has two screens so I extended the first with the second screen. It is more than a year with gameex works fine with my radeon xt1950 for both individual games single display that multi-display By chance these days I have done some testing applying settings screen individuals and / or with two screens but clones. The result is that I get an error similar to that reported in this topic, gameex does not start If I take the hard disk with gameex and put on any other PC it works The cab of my computer is updated as others and I have never had problems of any kind, I tried with all the theme but the problem remains. I have a dual core intel with 2gb of ram and a radeon xt950 and this is the part final of the error : 21:07:44.8 27/02/2008: Initialising DirectDraw 21:07:44.8 27/02/2008: Creating DirectDraw Device 21:07:44.8 27/02/2008: Using Device: Radeon X1950 Pro 21:07:45.0 27/02/2008: 0mb video memory available 21:07:45.4 27/02/2008: Setting Resolution to 640x480 32 bit color 21:07:45.4 27/02/2008: Creating DirectDraw Surfaces 21:07:45.4 27/02/2008: Creating Primary Surface - Full Screen Mode 21:07:45.4 27/02/2008: Creating Back Buffer 21:07:45.5 27/02/2008: --**-- 21:07:45.5 27/02/2008: Error: Valore non compreso nell'intervallo previsto. 21:07:45.5 27/02/2008: in Microsoft.DirectX.DirectDraw.Surface.CreateSurfaceFromHBitmap(IDirectDrawSurface ** lppSurf, HBITMAP__* hbm, SurfaceDescription desc, Device dev) 21:07:45.5 27/02/2008: in Microsoft.DirectX.DirectDraw.Surface..ctor(Bitmap source, SurfaceDescription desc, Device dev) 21:07:45.5 27/02/2008: in l.a(Surface& A_0, String A_1, SurfaceDescription A_2, Boolean A_3, Boolean A_4) 21:07:45.5 27/02/2008: in l.a(Boolean A_0, Boolean A_1, Boolean A_2, Boolean A_3, Boolean A_4, Int32 A_5) 21:07:45.5 27/02/2008: in l.a(Boolean A_0, String A_1, Boolean A_2) 21:07:45.5 27/02/2008: in l..ctor() 21:07:45.5 27/02/2008: 21:07:45.5 27/02/2008: It was detected you experienced a DirectX error. 21:07:45.5 27/02/2008: Please note the following for possible solutions to your problem: 21:07:45.5 27/02/2008: 1.
