E-Machines Presentor Q&A

January 11, 1996


Q: Is the PowerLink Presentor compatible with System 7.5 and later?

A: Extensive testing has not been done with system 7.5 and later. Therefore, final compatibility results are not available. With the product having been discontinued in 1994 and no further development underway, System 7.5 will remain unsupported.

Q: Is the PowerLink Presentor compatible with the PowerPC-based PowerBook Duos?

A: With the product having been discontinued in 1994 and no further development underway, PowerBook Duo models beyond the 280c or released since December 1994 will remain unsupported.

Q: Why does my LCD panel generate a scrambled image when it's attached to the Presentor? I followed the LCD's installation instructions, what's wrong?

A: Most LCD panels require separate or composite SYNC signals in order to have the display operate properly. The Presentor, when configured to operate a Macintosh compatible display, generates a SYNC on GREEN signal line. This green sync is usually incompatible with most LCD panels.

To connect a display such as an LCD panel to the PowerLink Presentor, follow the LCD panel manufacturer's instructions for connecting to a VGA or PC compatible system. Then, in addition, the E-Machines S5 adapter, part number 003-01637-00, must be used to connect the VGA cable from the LCD panel to the PowerLink Presentor. The S5 Adapter is included with the PowerLink Presentor. Or, the S5 adapter, part number 0008681-0001, can be ordered by dialing 800-977-7060.

After connecting the display, the PowerLink Control Panel must be used to select the proper monitor configuration. Set the display to operate as a VGA, External Sync monitor to have the LCD panel work properly.

Q: Why can't I change resolutions on my multi-resolution monitor?

A: The PowerLink Presentor will default to Apple cable sense codes whenever a monitor is attached. To override this default and to be able use the PowerLink software to switch resolutions, either a cable with E-Machines sense codes, or a cable lacking all sense codes is required. The E-Machines 3-BNC to Macintosh cable (0008773-0001) will supply this E-Machines cable sense. Order by dialing 800-977-7060.

Q: When I connect my Presentor to an external display, all I get is the desktop pattern and nothing else, what's wrong?

A: Since your Duo now operates as a two display system, the external display must be configured for color depth using the Monitors control panel. In addition, the Monitors control panel may be used to position the menu bar onto the external display, making it the primary monitor.

Q: When in NTSC mode, why are the edges of desktop not visible on the external monitor?

A: The NTSC standard screen resolution normally generates an overscanned image beyond the edges of NTSC monitors. Use the Presentor's PowerLink software to change the mode of operation to NTSC Safe Title. In Safe Title mode, the screen resolution will be lessened to 524 x 416, creating a black border and allowing the entire image to be seen.
