DLP, LCD and LED are three main technologies used for projection. DLP (Digital Light Processing) uses a chip made of tiny microscopic mirrors and a spinning colour wheel to create an image. DLP projectors deliver sharp images, don't need any filters, have a better response time as well as 3D capabilities. The effective lamp life of a DLP projector is only 2,000-5,000 hours.

On the other hand, LCD projectors use liquid crystal displays, have no moving parts and thus are generally less expensive. If you are on a budget a single chip LCD projector is ideal. Most LCD projectors come with long-lasting lamp and the lifespan can reach 50,000 hours, that’s much longer and cost-effective than DLP projector.

LED projectors are smaller and generate less heat. Do keep in mind that LED projectors have limited brightness compared to LCD or DLP so they are not recommended if your room has a lot of ambient light.

When buying a video projector for your home entertainment, it’s preferable to consider how much brightness that you actually need for your living room or home theater. In daytime conditions, higher lumens are strongly recommended because too bright a room can heavily impact the image quality and wash out everything you see on the screen. For rooms with dim light, there is not much restriction on the brightness, 100 ~ 1500 ANSI lumens can meet your satisfaction for bright and clear images.

Most projectors come with manual keystone correction or digital keystone correction. If you have a projector that only has manual correction, you need to adjust the lens manually because the correction is not that smart. Comparing to manual keystone correction, digital correction is flexible and much easier. Some projectors have a selected algorithm to make the image square automatically if the projector is at an angle. This can save you a lot of time when setting up a projector.

Projectors make more noise than TV. This is due to the ventilation that cools the device. To reduce the noise, a cool place is needed. Don’t put your projector in the sun and keep it away from any object that will impact optimal ventilation. By doing this, the cooling system makes less noise and the projector will not be overheated. The less noise from the video projector, the more you can enjoy the sound of your movie.

Full HD projector has a major advantage over TV: the feeling of truly experiencing the film or being only a few meters from the actors or a football match, for example. In this way you can transform your living room into a movie theater to enjoy with your families or friends! You can also enjoy your life-size video games.

Generally speaking, the higher the resolution, the better the image quality, and the more the projector will cost. Higher resolutions can display more detail in the picture, and can reduce or eliminate the visibility of the pixel structure. Both of these are highly desirable in good home theater. The native 1080p resolution projectors are most recommended for home theater, as they are affordable to most projector users.

Projectors have the main specification which is called a “throw ratio”. Throw ratio is basically the specification which is determined by the first two pieces of the information in an equation.
