Setup and Installation

The NEXTSTEP driver automatically sets all of the necessary parameters as specified in Configure.

In Configure, the 'width' and `height' parameters are the width and height of the display in pixels. The `refresh' parameter is the refresh rate of the monitor in Hz. The `colorspace' parameter is of the form `BW:x' where `x' is the number of bits/pixel, or `RGB:xyz/w' where 'x', 'y', and 'z' are the number of bits/component and `w' is the number of bits/pixel.

Supported Displays

NeXT designs and tests its display adapter device drivers using displays that can support display modes with very high resolutions and non-interlaced refresh rates, such as the NEC 5FG, NEC 6FG, and Nokia Multigraph 445X. Read the owner's guide that comes with your display to ensure it can support the display mode you set in Configure.

Warning: Some vendors claim that you can use their display adpaters at display modes with resolutions and refresh rates that exceed what their RAMDACs can support. You can permanently damage your display adapter and computer by doing this. Read the owner's guide that comes with your display adapter or contact its manufacturer to ensure that your adapter's RAMDAC can support the display mode you set in Configure.
