A front projector has a two piece system: a projector that creates an image and screen that reflects it. Even with two pieces, projectors are easy to set-up. There are three types of technology for front projectors. They are DLP, LCD, and LCOS.
DLP, or Digital Light Processing, range in price from affordable to very expensive. They are typically used in movie theaters and have great motion resolution. LCD has the same technology as flat-panel TVs. They are generally very affordable. LCOS, or Liquid Crystal On Silicon, is a hybrid of DLP and LCD. They are typically the most expensive.
The Pros of Projectors
Because projectors are lighter and easier to set-up, they can be a lot larger than typical television screens. Projectors can be 50 inches, or four feet, tall. You can watch a movie on a screen that fills your entire field of view right in your own home. The screen can even double as a giant computer screen. You can see every word, every strand of hair, every pore, and every blade of grass. Your home will be the for movie nights, watching TV, and big sporting events.
Easier on the Eyes
Most people think that having a screen that big would hurt your eyes, but that isn’t true. Filling the larger percentage of your visual field, combined with less brightness, makes the projector screen very comfortable to watch.
Projectors take up less space because they can be hung on the wall after you hang your projector from the ceiling. True, TV screens can be mounted on the wall, but most people don’t go through the trouble because they are heavy and it damages the wall. Having the projector screen on the wall saves you space on your floor and opens up the room.
The Cons of Projectors
No matter how bright your projector is and no matter how well-made the movie you’re watching is, any ambient light can flood the room and wash out the image on the screen. You’ll need to have total control over the light coming into the room, otherwise you’ll only be able to get good picture quality at night.
Most all projectors have UHP lamps and they last a few thousand hours. They are expensive to replace, costing a few hundred dollars at a time. You’ll probably have to buy a new lamp every year or so; if you’re lucky every other year. LEDs are starting to replace UHP lamps, but the prices are still high. The best option is to get a quality-performance UHP-based projector and pay for the new lamps.
UHP and LED projectors generate a lot of heat and need small fans inside the projector to cool them down while they’re running. However, the noise that comes from these fans varies greatly. Inexpensive and small projectors can be very loud and disruptive. Larger and more expensive fans can be quieter. It’s up to you to choose the best model.
