Connecting 2 External Monitors to a Laptop?
I was wondering if it was possible to use 3 displays on a notebook - the integrated one plus two external. I have IdeaPad Z570 with two switchable graphics cards and VGA and HDMI output. So far it seems that it is only possible to use two monitors at a time (it's possible to have the integrated disabled and both external enabled, but I can't seem to work it out to use all three).
Is there a way I could use all three at the same time? Windows 7 recognizes them, I can change their positions etc., but one of them is always greyed out :/
Thanks for help
