The Power Macintosh supports "on the fly" resolution switching with many third-party multisync monitors (also called multiple scan displays). However, an adapter is required so the Macintosh can detect the proper multisync mode.
For NEC monitors, there is an adapter named "Power Macintosh Adapter" which lets you change resolutions through the Monitors control panel, like you would if you owned an Apple Multiple Scan Display. NEC adapters are available by calling NEC.
Macintosh Centris, Quadra, or LC Owners
=======================================
With a Centris, Quadra or LC, you can use NEC's "DPI on the fly" software which provides a similar ability to change resolutions.
The "DPI on the fly" software is not compatible with the Power Macintosh.
