eVGA e-GeForce2 MX TwinView Plus Review

TwinView Extended Mode

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 the screen. 

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 enabled:

The zoom feature should be particularly useful to the designing folk who must constantly switch between standard and zoom view to examine their masterpiece.
