When you fire up the hardware the GXM will automatically find the highest resolution supported and choose that by default. On Apple Cinema Displays it will find only the one default resolution, which is also the highest one supported on the Cinema Display. In our case it has already populated two of the empty boxes. If we were using a Dell or other branded set of monitors we would be able to further populate the four boxes with another set of resolutions. We would grab these from the drop down menu at left in the control panel and hit the right arrow button. The left arrow button moves resolutions back out of the four boxes on the right.
Other options in this control panel include a button which automatically will configure based on the attached displays, as well as reset to manufacturer settings. These are useful when things get out of whack. At the bottom of the control panel is basic information on the Matrox GXM unit, such as serial number, firmware version and the like.
The next settings option in the Matrox PowerDesk software is Change Display Setting. This panel allows you to choose an available GXM display option from a drop-down menu. In our particular case using the Apple Cinema Display (20-inch) in pair configuration, we have just two choices: use one external display or two. (see image 05) Other key options are setting the location for the menu bar (which you can also set in the default Mac display preferences) and more importantly the left or right choice for the GXM location. This latter choice determines which direction (left or right) the external monitors are located relative to the laptop display so when you move the mouse off the laptop display in the right direction it follows over to the left side of the attached external monitors. Alternatively, if you have your external (GXM) attached displays on the left side you would choose the Left radio button.
The last configuration panel allows the user to swap the active window with a keyboard shortcut. The keyboard shortcut moves the active window from one of the GXM displays to the other. There is also a dock configuration control. And this completes the review of the Matrox PowerDesk software. (see image 06)
