POWERBOOKS AND IBOOKS

IMPROVE EXTERNAL DISPLAY QUALITY

The Annoyance:

I frequently use my PowerBook with an external VGA display. The picture isn't as sharp on the external display as on the built-in display. The external display is what my audience sees, which ends up making me look bad.

The Fix:

Your PowerBook doesn't have enough video RAM (VRAM) for both the built-in display and the VGA monitor, so the PowerBook shortchanges the external display. The solution is to shut the built-in display off, so that all of the video RAM is devoted to the VGA display. You might be aware that you can close the PowerBook and still operate it with an external display and an external keyboard. That's no great trick, but did you know that you can shut off the built-in display while keeping the PowerBook lid open so you can access the keyboard? An open lid also keeps the heat from building up.
