Connecting Video Equipment

The Power Macintosh AV card provides additional ports for connecting video equipment so that you can view TV and other video images on your computer monitor and store the images on your hard disk. You can also view the Macintosh desktop on a television screen attached to the computer and record images from the desktop to a videocassette recorder (VCR).

Connecting a Television

You can connect to your computer any television that has either an S-video or composite video input port and Audio In ports. The television displays a mirror image of the computer monitor display, and (if the television has speakers) plays the sounds generated by the computer. This capability is especially useful for giving presentations if you have a large-screen television.

There are typically millions of these subpixels on an LCD display. For example, the LCD panel used in the Apple Cinema HD display is made up of 2.3 million pixels and 6.9 million red, green, and blue subpixels. Occasionally, a transistor does not work perfectly, which may result in the affected subpixel being turned on (bright) or turned off (dark). With the millions of subpixels on a display, it is quite possible to have a low number of faulty transistors on an LCD. Therefore, a certain number of subpixel anomalies is considered acceptable. Rejecting all but perfect LCD panels would significantly increase the retail price for products using LCD displays. These factors apply to all manufacturers using LCD technology not just Apple products.

Should the system freeze during the long memory test, use the dash count to identify the DIMM last tested. Table 3 lists the dash count and the DIMM slot tested
