This article describes how to setup the Power Macintosh G3 (Blue and White) Teacher Bundle for video mirroring.

2. Connect the video-out adapter that came with your computer (it is a Y-cable with a plug on one end, and two sockets on the other end) to the TV-out port on your ATI Xclaim VR card.

3. Determine if your TV or VCR has an S-video or composite (RCA) video input. Attach the appropriate cable to the appropriate socket on the video-out adapter.

Notes:

- If your TV or VCR has both S-video and composite connectors on it, you only need to use one of them. S-video will generally produce the highest quality image.

- You can connect two TVs or VCRs to your computer at the same time, one using S-video and the other composite (RCA) video, connected to the appropriate sockets on the video-out adapter cable. Both devices will display (or record) the same image simultaneously.

You can now either display video on the attached monitor and the TV or VCR (simulscan), or strictly to the TV or VCR. There are several ways to accomplish this.

Using the Monitors and Sound control panel:

1. From the Apple menu, go to Control Panels, and open Monitors and Sound.
2. Choose the resolution at which you wish your image to be displayed. Depending on the model of monitor you have attached to your computer, you may have some choices for Simulscan. If you choose one of these resolutions, the image will be displayed on the monitor and on the device (TV or VCR) attached to the video-out adapter.

3. You should get a dialog box alerting you: "The setting for your monitor has been changed. Click OK to confirm that the monitor is displayed correctly, or click Cancel to revert to the previous setting." If you do not make a choice, it will automatically revert to the previous setting.


Using the Control Strip:

1. From the Resolution Control Strip module, choose the resolution at which you wish your image to be displayed. Depending on the model of monitor you have attached to your computer, you may have some choices for Simulscan. If you choose one of these resolutions, the image will be displayed on the monitor and on the device (TV or VCR) attached to the video-out adapter.

2. You should get a dialog box alerting you: "The setting for your monitor has been changed. Click OK to confirm that the monitor is displayed correctly, or click Cancel to revert to the previous setting." If you do not make a choice, it will automatically revert to the previous setting.


Using the ATI Displays control panel:

1. From the ATI menu in the Control Strip, or from the Control Panels folder (accessible under the Apple menu), open ATI Displays.

2. Click on the Mac2TV hot spot on the control panel.

3. A detailed settings window will appear, wherein you can specify your video preferences. For more information about this window and how to optimize your TV display, please refer to your ATI Xclaim VR Manual.pdf.

4. One you select your settings and turn Video Output on, you should receive an alert that Mac2TV is about to turn on and it will dim your monitor display. Simulscan is not an option in Mac2TV.
