If you are planning to buy new projector, following guidelines will be helpful for you: Choosing the right technology There are mainly three types of projection technologies that includes LCD (Liquid Crystal Display) projectors, DLP (Digital Light Processing) projectors and LCOS (Liquid Crystal On Silicon). Among all of these technologies, LCD is the oldest and LCOD is the newest technology used for projectors.

Checking the portability Portability is one of the crucial factors to be concerned while buying video projector. Specially when you are buying business projectors, they must be easy to carry from one place to another. Portable projectors are also easy to install and are available at affordable projector prices. Ideally a portable projector should weigh less than 4lb. If you have no plans to travel with your projector, still you want easiness in moving it from one room to another, you can get many choices ranging in 10 to 15 pounds in weight. Consider brightness levels While selecting a projector for your room, you should consider the brightness level it provides. Brightness is typically measured in ANSI lumen. If the room in which projectors is to be placed is smaller or average in size; 1000 or 1100 Lumens is the minimum. However, if projectors are to be placed in large rooms such as conference halls, small auditorium, they require at least 1500 or more Lumens. Projector price will increase as per your requirements. Know the right resolution Resolution is an important factor to be concerned to take decision of buying video projectors. There are typically four main categories of resolution including UXGA, SXGA, XGA, and SVGA. Usually, how much resolution should be chosen depends on how much you can afford to have. Ideally 1024 x 768 (XGA) is considered as standard graphics resolution for any video projector and 1280 x 1024 (SXGA) is considered as high-resolution. Check Contrast Ratio Contrast ratio compares brightest whites to the darkest dark. The larger the difference, the richer will be the image. Connection alternatives It is important to check the number of connection options available with the projector. Typically, the more is the number of connection, the better it will be. Most of the projectors come with VGA cable, composite video cable, S-Video cable and M1-A connection. Newer projector models also have DVI inputs, Ethernet and USB ports. Extra Features In order to lure customers, most of the projector brands are coming up with projectors with many extra features such as built-in speakers, direct digital video input and a remote control. You should also check different projectors for advanced features available with them. Keeping above points in mind, will be helpful in choosing the right projector at the right price for your different requirements.
