OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: GeForce 9600 GT/PCIe/SSE2
OpenGL core profile version string: 3.3.0 NVIDIA 340.76

I read some
http://us.download.nvidia.com/XFree86/Linux-x86/346.16/README/xconfigoptions.html#IgnoreEDIDChecksum

and add

Option "UseEDID" "FALSE"

to /etc/X11/xorg.conf.d/nvidia.conf this wiil be good idea ?
