Where can I learn the capabilities of using external displays with my X301?
I've never had a problem when plugging in any projector, but when I plug an external display into the VGA port, I can't increase the resolution to take advantage of the larger display. My goal is to use either one large external display or two mid-size external displays for GIS work in my office; the laptop is powerful enough for GIS but the small screen is a handicap.

independent mode is just a windows setting, where the two LCD displays two independent image.
The image describes the different video cable connectors that you encounter (your laptop only have the vga and displayport connector).
In order to help you further, you must tell me the model type of the monitors that you are using.

My two monitors are 19" ViewSonic VP191, about five years old. Each has a DVI socket and two VGA sockets.
My X301 is Type 4057, XB1.
When I simply plug a VGA cable into the laptop and monitor, I can "duplicate these displays" and see the same image on both monitors. However, even on my 4:3 monitor, I can get only a widescreen view, wasting nearly a third of the monitor's space.
The highest resolution the laptop says I can choose is 1440x900, but that yields an "out of range" error message on my external monitor; the highest resolution that displays on both monitors is 1360x768 -- which looks fuzzy.
So my question #1 is whether there is any way to fill the entire screen of my 4:3 external monitor with a crisp image, preferably at its native resolution?
Question #2 is, if I buy a DisplayPort-to-DVI cable, can I use my second monitor as well? Could I also fill it to its native resolution and have my GIS software extend across both screens?

if you duplicate the display, then both of the image would have the same resolution as the primary display.
Go into your intel display property right click on your desktop, then check under the monitors section, you can select the extended and clone mode.
19 inch external monitors usually support 1280 x 1024, so select this resolution for the viewsonic external monitor.
The only way to support 2 external LCD is for you to switch off the internal LCD. If you need 3 LCD support, then the second external monitor would need a USB2DVI or USB2VGA converter.
Personally, i would use a digital connection for external monitors (i.e. displayport), as the picture quality will be better (less noises and distortions). Otherwise you are not doing justice for your viewsonic LCD (which uses the MVA LCD panels).

Thanks so much, now I'm understanding how this works.
I will take your advice about avoiding a VGA connection to my external monitor.
I don't need the laptop's internal display when I'm using the external monitor. So if I want two external monitors, I just hook up one through the display port connector and the second through a USB2DVI converter? Would that allow the two external monitors to work together, to extend my desktop across both?
