*I am using the same Nvidia card as you, and have had no problems with 
it...I use the driver 1.5.8 Nvidia 96.49.17 the default is 1600x900 
refresh rate 50hz the Rotation is at normal...Display depth 24, the 
metamodes I have set at 1024x768...I have a 20" HDMI monitor and the 
screen is very clear on everything being shown...
