DX 10 with two graphics cards

[Orphee01 8]

Hi,

 

i have a problem, i can't run dx10 with two graphics cards  :angry: , but it work with DX9

 

My configuration : 

 

- the gigabyte GTX770 4Go  : 

 

     - the number 1 on picture, the main monitor 

 

 

- the Gigabyte GT610 : 

 

     - the number 2 on picture, the "accessory" monitor (wx radar from reality XP, VOX atc and FS2crew)

     - the number 3 on picture, the monitor CDU from plug n fly

 

 

This configuration work without any problem on DX9, but i switch to DX 10, i can't have fullscreen! I start fsx in windowed mode (dx10 with muliple monitor technique), after start completed, when i switch to fullscreen, the "fullscreen" take just the half center from the main screen (the monitors are set in cfg)!

 

 

I test with a new fsx.cfg, same problem, but when i test with two monitor on the SAME graphic card, i don't have this problem!

 

I have the latest driver installed (335.23).

 

 

 

Thanks for your help
