Hi, i have a problem with this driver and with my tv. on DVI-Connection i can’t make the change to 1280x768 why the driver will set the horizontal frequency to 17hz but the monitor can not detect the signal with 17hz. Please help me with this little problem.

sorry there, i have the tv connected by HDMI and not by DVI. Sorry i am so nervosly about writing this. pleas sorry for my bad english

hi there again, now additional to the problem. I don’t want to use the DVI Prot with an DVI to VGA adapter for this TV, because when i change the resolution the tv feind everytime no signal for 5 - 6 seconds until i see the desktop again. Thats not so on a connection via HDMI, on this connection via HDMI the resolution change fewer than 1 second. Thats the reason becouse i prefer to use the HDMI Prot than the VGA with Adapter.
I Hope i could help You find the Bug on the Driver for my NVidia GeForce GTX 560 Ti.
Thanks in advance
