Default GTX 550 Ti - no i2c

Just bought a new Zotac GTX550 Ti. The i2c is absent as a result I can't control my monitor settings on Samsung 971p. As this monitor doesn't have manual controls I cant to adjust it at all. Is it a bug or my card really doesn't have support of i2c ? I had 7950 before with same kernel and same hardware and it worked with i2c as expected

I would reinstall the nvidia driver as your nvidia kernel module doesn't match the nvidia GL libs.

The problem was in file permissions (/dev/i2c-*), fixed that and it works now as expected. Thanks
