Power Point Projectors: What You Should Look For
If you need to purchase a power point projector for an upcoming presentation or deadline, time is of the essence and with all the technical jargon and options, this task can really seem overwhelming. Hence this article has been written with the neophyte in mind. With all the buzz words and projector jargon out there, your knowing the basics will be a great help to you in your projector search.
Tiny dots of light called pixels make up the image you see on your laptop computer screen as well as the image shown by a modern projector. The number of pixels in an image is it’s resolution, this is often determined initially by the video source. In the best case scenario, your projector will operate natively at the same resolution as your video source, in this case the laptop containing your power point presentation.
Amazingly, not long ago the common resolution used to be rather crude VGA (640 x 480), this was later replaced by SVGA (800 x 600) and the more modern quality XGA (1,024 x 768). One can even venture into the really high end resolutions such as SXGA and UXGA, (1,280 x 1,024) and (1600 x 1200) respectively. This ultra high-end resolution comes with a high price tag. Someone who is multi lingual, may be fluent in several languages yet they are most fluent in their native language which is often their first language. It’s the same way for projectors regarding resolution. Many projectors can operate at several resolutions but they are optimized to operate at their native resolution.
Brightness is a key characteristic to not in your projector search, it’s especially important for making presentations on the go in rooms that might not have optimal darkness. Projector brightness is measured in lumens. Because of the significant influence of the screening environment, ambient light and projector brightness on the visual appeal of your projector presentations, lumens (units for light intensity) are an important spec to look at when choosing a projector. Huge venues or brightly lit rooms that remain so during a screening require projectors that are capable of a great amount of lumens, possibly 5000 or more. Less lumens would be needed for a small audience, with a smaller screen in a well darkened room. In this case 1000 lumens could work fine. When you see the term ANSI lumens, just know that ANSI is a common standard method of measuring lumens.
The term “throw distance” is also a common one in projector speak, it simply means the distance that is the optimal placement for a projector from the screen. For projectors that are designed to operate in large venues, further than 15 ft back from the screen, large throw or long throw lenses are the norm. With a short throw power point projector, your can make a presentation with the projector behind you, close to the screen and not have to worry about casting a shadow over your wonderful power point graphics.
Also important when using projectors for power point and similar presentations is interface connectivity and resolution, your computer needs to be compatible with your projector. Usually you won’t have to worry too much about computer – projector compatibility as these devices adhere to some general standards now days. In any case, still check to make sure you have the proper ports and cables at your disposal to connect your devices. Again, when everything is compatible, that’s one less thing to worry about.
