As the topics aid above ,I have a problem with dual monitor via HDMI.

I want to connect my laptop to the second monitor via HDMI cable.

I can connect it with out any problem but the the second is display Not optimus , recommend 1600*900 60Hz

And the font in the second in second is very blur and it have some cross line on the screen (Not the monitor problem)

I tried to change the second monitor display to the recommend setting but it not working.
