I have docking station for my new Dell Latitude and I plugged in one monitor via VGA and the other DVI.Â However, the VGA monitor remains blank, and I don’t see a third monitor in display settings.Â Do I need to do something on my PC to make this additional monitor work?
I saw this question as a comment to another post on using multiple monitors with a laptop. The answer is that the Dell laptops, like my Latitude D500, D600, and D820s, only support two displays at once. So, you can connect one external monitor and use it side-by-side with the laptop’s built-in LCD display. Or, you can use two external monitors and close your laptop’s lid. But you can’t keep your laptop open and use the built-in LCD display along with two external monitors.
If you want two external displays alongside the internal display, you’ll need to use a USB video adapter as this post described. The downside to that is that the resolution is pretty limited, and if you’re already using multiple monitors, you probably don’t want the low resolution. Otherwise, you can use a second computer, and run MaxiVista.
