“What do I need to know before buying a video projector?”

Nowadays, many people are intended to purchase a projector for a broader horizon and a better watching experience. But most of them are asking this kind of question when they should make a decision. Below are five major factors that will help determine whether a projector is right for you.

Resolution

Projector resolution

The total number of pixels that a projector is capable of displaying defines the projector's native resolution. Resolutions range from 480p to1080p for HD viewing, and up to 4K Ultra HD for impressively sharp movies and shows. Higher resolution means a sharper looking image and better compatibility with high-definition sources. And there are SVGA(800 x 600 pixels), XGA( 1024 x 768 pixels)WXGA(1280 by 800 pixels)available. If most of your viewing is HDTV, consider a projector with 1920x1080 native pixel resolution at best.

Be careful about choosing 4k projectors as it usually means a higher cost and actually there is a lack of 4k projectors in the market.

Lumens

Projector lumen decides the brightness. The higher the lumen is, the brighter it is. Usually be sure to look for two-lumen specifications: One for color brightness and one for white brightness. For most home theater projectors, lumens should measure between 2000 and 3500 lumens when moderate ambient light is present. For a movie projector in an environment with some ambient light you might want a rating of 5,000 lumens or more.

Contrast ratio

Another important factor is the contrast ratio as it is a ration between the light and dark area, a projector with a 2000:1 contrast ratio means that the white image is 2000 times brighter than the black image. If the contrast ratio is low, your image will look washed out. So make sure it is highly possible.

Lamp life

There are 4 types of Lamps used in Projectors: Metal Halide lamps, LED Lamps, Lasers and Hybrid Projectors. The rated lifetime of normal Metal Halide projector lamps is 3000 hours. the LED projector lamps have a Half-Life of over 20,000 hours, some even claiming 60,000 hours. Laser projectors have very good pictures with high contrast ratios and the Laser lamp life in projectors is in the range of 30,000 hours plus. Hybrid Projectors are using both led and laser sources and these projectors are quite bright and have a long life while it is expensive. Most lamps will last for about 2000 hours, so just consider your budget and choose the longest-lasting lamp.

Portability

Projector size means if it can be carried for traveling, and it also determines how much space should be taken for its installation. A portable projector surely makes your presentations shine and make the installation progress goes well, even you can pick the proper screen size. Make sure if it is friendly for the novices to set up.
