I installed Snow Leopard on a sony vgn-fz340e and I have the problem that you enable the video card with natit nvinget or any of the injectors that can be used, the video screen does not come out of the notebook, if not for the vga output side, and tells me not detect any screen.
The notebook has a nVIDIA GeForce 8400M GT (Sony) with VGA and HDMI output.
I install the retail leopard 10.6.2 and then throw him comboupgrade.
If someone comes up with some solution to this issue, I would appreciate.
Since already many thanks. Greetings.
Use the OSX86Tools. Generate EFI String -> Custom and Search your Graphic Card.
