Extended mode really shows off the featues of TwinView as it fully exploits the two
independent display pipelines of the GeForce2 MX and allowed me to tinker around with many intriguing settings.
The primary feature of Extended mode is that it allows a second display device to become an additional part of your desktop real estate.
As the above picture demonstrates, a single window can be
split across multiple monitors. This is similar to the effect when rows of televisions are
set up to display one large image with each television sharing a part of the entire image.
Since Windows recognizes that it's being displayed on multiple monitors, the display properties control panel allows
you to configure each display independent of the other.
A missed click led me to an intriguing discovery...
... the monitors do not have to be aligned horizontally with each other, which
leads to a desktop such as this:
A more practical purpose would be when the monitors are aligned on top of one another. In this case, the desktop space is shared vertically.
I also toyed around with the resolutions of both monitors.
Which produced quite a deformed desktop. :)
Most people can't afford two identical monitors, which is
quite understandable. But Extended mode allows you to utilize the old unit you
were about to throw away because it's maximum resolution is only 640x480.
Extended mode provides more configurable options than Clone mode. Here's a large image of the virtual desktop my monitors were supporting. The left portion is running in 32-bit color with a 75Hz refresh rate, while the right half is at 16-bit color with a 60 Hz refresh rate.
Another nifty feature of Extended mode is the zoom capability.
In this mode, a pre-determined area around the cursor on one display can be
magnified on the second display.
The magnification levels vary from 2x to 32x, but at such a high
magnification rate, anything is barely distinguishable as a pixel can cover half
There is no screen that is zoom only as they both
interchange the feature, depending on where the cursor is located. The amount
of zoom is easily configured by a built in application, dubbed the Desktop Display
Manager, which is covered next.
Here's a picture of my virtual desktop with the zoom feature
The zoom feature should be particularly useful to the
designing folk who must constantly switch between standard and zoom view to
examine their masterpiece.
