Q&A

Q1:I want to buy my own projector to take on presentations. How do I choose one?
A1: Choosing a projector is a bit like choosing a laptop—a big part of it is how much you can comfortably carry. Smaller projectors are more expensive.

The main factor is the type of venue where you expect to present. Make sure that you get a projector with enough power for the largest venue where you anticipate speaking, with the most lumens (light power) you can afford. Finally, check on the price of spare bulbs and how long they'll last in your projector. If possible, try or rent before you buy.

Q2:The audiovisual staff tells me the projector is all set up, but there's no picture on the screen. What could be wrong?
A2: Projectors usually have three modes: off, on, and standby. If the projector is tested and left alone, it will go into standby to save the bulb (the power light is often yellow or orange). Pressing the power button one more time, quickly and gently, will wake up the projector and restore your image on screen.

Be careful using remotes for projectors. Features such as freeze frame and blank screen can suddenly and abruptly make you think something has gone terribly wrong, when all you've done is gone trigger-happy.

Q3:I use a regular external mouse on my laptop instead of the trackpad. Can I also use a presentation mouse and keep my external mouse attached for emergencies?
A3: If the presentation mouse is USB, rather than PS-2, it will probably get along with a regular external mouse. Problems tend to occur when you need to load special mouse drivers. If your laptop finds both mice instantly, you should be all right. If you need to load extra software and the mice have icons on the system tray, be careful. In general, more than one mouse driver at a time is a prescription for disaster.
