powerpoint projectors
There are a few things to consider when searching for the right powerpoint projector. A businessperson should look for how well the projector interfaces with computers, the powerpoint projector's native resolution, and how bright the powerpoint projector will appear.
In most business settings, powerpoint projectors are connected to a laptop/notebook computer. Most portable computer has a VGA connection. These are normally 15-pin connections and are blue in color. More modern laptops have a DVI connection. This connection is usually white and is a little wider than a VGA port. The powerpoint projector one chooses should allow for connectivity to one or both of these ports. If the powerpoint projector is to be connected to a desktop/tower PC, the same rules apply. Desktop/tower PCs all have either a VGA or DVI connection, sometimes both.
The connection is pretty universal but native resolution isn't. If the powerpoint projector is to be used by many different people, it should have a native resolution that is pretty common for laptop computers. At the moment, that resolution (for fullscreen laptops) would be XGA, or 1024x768. This is a good resolution for powerpoint projectors as it is very universal.
Lastly, one should take into consideration the ambient lighting where the powerpoint projector will be used. One should also consider the physical size of the screen the powerpoint projector will project. A good rule when calculating the lumens for a powerpoint projector in a business environment is if the diagonal size of the screen is less than 100 inches, a projector of 2000 lumens will be very adequate. Between 100 and 120 inches, the powerpoint projector should be at least 3000 lumens. Between 120 and 150 inches, the powerpoint projector should be at least 3700 lumens.
Using these simple rules, can help any business person with little understanding of lumens and resolution find the right powerpoint projector.
