If you’re a mobile professional who uses projectors for training, educational or sales presentations, here’s what you most need to know to pick just the right model.
How many lumens?
The more lumens, the more light—so how much do you need? Do your presentations rely on brilliantly lit images projected in well-lit rooms or those with a large audience? If so, look for a projector in the 2500 to 3500 lumen range. For those professionals whose training presentations are done in darker and smaller rooms, projectors in the 1200-2000 lumen range will suit you fine.
When you’re on the go, weight counts—especially if you’re packing a heavy laptop in addition to your projector. Featherweight models weigh in at around 4 pounds, while the bigger portables top the scale at close to 13 pounds. If weight is an issue for you, avoid the heavy projectors, especially if they’re loaded with features you’ll never use; look instead for the lightest projector with the most useable features.
Most lightweight projectors have source input for one computer and one video, while some larger portables have two computer and one video input sources. For most professionals, the single computer/one video source is adequate for your presentation needs.
Do you building images look like they’re falling inward? Then you definitely need a projector with keystone correction. This is the on-board adjustment to straighten up leaning buildings. Lower level projectors have an automatic keystone correction of about 15-degrees; higher end models have both a vertical and horizontal correction, some up to as much as 40-degrees. If your images include a LOT of leaning buildings, this may be a deciding factor.
Easy setup and operation
Look for projectors that have a storage slot for the remote control within the unit itself—if not you’ll spend a lot of time wondering what you did with the remote after your last presentation. Other features to look for include: cable lock for security, color coded cables (for easy connectivity), quiet operation, digital zoom, and a long lamp life. If it’s in your budget, look for units with wireless capability—this will allow you set up your projector and your laptop without cables, independent of each other, in positions that are optimal for viewing.
