Using 2 Monitors on Windows 98se Computer

[small]

This allows you to use two monitors on a single computer. You can use one monitor for cash register program and the second monitor for Big pole for customer Display.


To enable the multi-display feature on a Windows 98 SE machine, follow these steps:

1) While the computer is turned off, add any additional display adapters (video cards) and monitors.

2) Start the computer and boot up Windows. Install the display adapter and monitor drivers (if necessary), and then restart your computer if you are prompted to do so.

3) Click the Start button, select Settings, and then click Control Panel.

4) Double-click the Display applet, and then click the Settings tab.

5) In the Display box, click the adapter you want to use, and then click the Extend my Windows desktop onto this monitor checkbox to select it.

6) Click OK.



There are a few quirks with this technology. According to Windows 98 Second Edition, the Unauthorized Guide (Que), by Paul McFedries, there are five you should keep in mind.

Quirk #1: One of the video card/monitor combinations is designated as the primary card, and, as such you can only run DOS full screen on that screen.

Quirk #2: When you run DOS in full screen on the primary screen, you can't use your mouse on the secondary monitor.

Quirk #3: Some programs display dialog boxes and shortcut menus on the primary monitor, even though the program is running on the secondary monitor. Some prorams hate dual monitor set-ups.

Quirk #4: If you try to drag the program's window onto the secondary monitor the program will hang. Graphics programs particularly resist.

Quirk #5: If you move a program window to the secondary monitor. That program will likely open in the secondary monitor the next time you start it


All of the video adapters that are used in a computer with multiple-display support must be Peripheral Component Interconnect (PCI) or Accelerated Graphics Port (AGP) devices that use multiple-display-enabled video adapter drivers that are included with Windows 98. Industry Standard Architecture (ISA) and Extended Industry Standard Architecture (EISA) video adapters are not supported.


The video adapters that are installed in your computer do not have to be identical. Each video adapter and monitor combination is separately enumerated by Windows; you can configure each combination to use different screen resolutions and color depths. For example, you can set the primary adapter to 1024 X 768 pixels with 256 colors and the secondary adapter to 800 X 600 pixels with 32,000 colors.



You cannot use video adapters with the following chip sets as multiple-display support devices:
Permedia (this does not include the Permedia NT and Permedia-2 chip sets)


Supported Video Adapter Chip Sets.

You can use any combination of the following supported PCI-based video adapters with multiple monitors. Only video adapters that are based on the following chip sets work as primary and secondary video adapters.

Note that only the PCI adapters that are listed below are supported as the primary adapter. However, other PCI adapters may work even though they are not supported, but you must use the specified driver.

The following drivers are supported by Microsoft and are included on the Windows 98 CD-ROM:

If the adapter uses one of these updates, Windows 98 will recognize the video adapter as a Trio 64V+, provided the Microsoft driver is used. If the adapter does not use one of these updates, it is recognized as a Trio 32/64. Some OEM drivers can use any update. Be sure to note carefully which Microsoft driver Windows 98 selects when you use this adapter.)
