    On my notebook, I would like to have three monitors. Windows will only allow me to choose 2 at a time. I have a dell xps 1640 and I have hdmi, displayport, and vga.

    Thanks

    This depends strongly on your graphics cards and drivers. Most will only allow 2 displays at a time, so either notebook screen and one output, or any 2 outputs and no notebook screen. There are alternative solutions, but that would require buying (expensive) external adaptors.

    Hey there,

    I am currently running vga out to my lg flatron monitor and hdmi out to my toshiba regza tv, your gpu and drivers will definately play some role, but generally you can! :)

    You cant use your LCD, HDMI and VGA though :(.

    Yeah I know that I have a vga monitor and a lcd tv (hdmi). I have ati modded drivers. But I would probably need some other application to all me to do it.

    A couple ways to exceed the 2 display limit of just about all current graphics chips in notebooks:

    a) use a docking station with another graphics chip inside, if available. just because it has additional monitor ports does not mean it has an additional chip.

    b) use a USB display solution like http://www.displaylink.com/

    The HD 5xx0 series should fix this.

    How good would the display quality be? I mean, HDMI has something like 10 Gbps of bandwidth, versus USB 2.0's 480 Mbps.
