I have a Sony VPCZ1 notebook with a GeForce GT 330M. I have it in a Sony docking station which gives me a DVI-D out and a VGA out. I was hoping that I could run two external Samsung monitors with this setup. One from the VGA and one from the DVI-D. Apparently the graphics card does not support two external monitors. I bought the digital dual head to go box and with this i can power both external monitors and the sony, however the resolution on the external monitors is terrible. The Sony is set on 1600x900 and the two external displays thru the dual head to go is set at 3200x1200. I can hardly read the screen. Is there a way to download a different resolution or does anyone know if the graphics card in the notebook should indeed support dual monitors without the use of the dual head to go?
