In order to enable video mirroring on a Power Macintosh G3 Mini Tower, use the "TV Mirroring" portion of the Control Strip, which is automatically installed on Power Macintosh G3 Mini Tower computers that have the A/V Personality Card. You can identify this by looking for the Control Strip portion that has a picture of a TV with antennas.
Within this control strip, you have several options:
- turn Video Mirroring on
- use NTSC standard
- use PAL standard
- overscan
- leave monitor on
To start video mirroring, choose "Turn Video Mirroring On".
Troubleshooting
Question: What if the TV Mirroring control strip is not present?
Answer: Make sure you have a Power Macintosh G3 Mini Tower computer with the A/V personality card.
If you have a Power Macintosh G3 Desktop computer, or if you do not have the A/V personality card, then the only way to use video mirroring is through a third-party PCI card. In that case, you should follow the instructions that came with the video card.
If you have a Power Macintosh G3 Mini Tower computer with the A/V personality card, and the control strip is not present, perform a "custom installation" of the "Control Strip" control panel with your Power Macintosh G3 CD.
Question: I have chosen "Turn Video Mirroring On" but I am getting no video on my TV.
Answer: Check your connections and make sure that the RCA or S-video cable is going from the "video out" ports of your computer, and the "video in" ports of your TV or VCR. Make sure that "Use NTSC Standard is selected within the TV mirroring control strip. Check the video input ports of your TV or VCR with another device.
Question: When I turn video mirroring on, my monitor turns off. Why won't it display to both monitor and my TV simultaneously?
Answer: Check the TV Mirroring portion of the Control Strip and make sure that the option "Leave Monitor On" is selected. If "Leave Monitor On" is disabled, then make sure your monitor is capable of displaying video at one of the following resolutions:
512 by 384 at 60 Hz
640 by 480 at 60 Hz
800 by 600 at 60 Hz
832 by 624 at 60 Hz
If your monitor does not work with one of those resolutions, it will not be able to display video simultaneously with your TV.
Finally, make sure that both your monitor and TV were connected to the computer before it started up (if you connected your monitor after the computer started up, you will need to restart).
