Home Theater Plasma TV VS Projectors

Home Theater - Plasma TV VS Projectors
By Jakob Culver

Many homeowners are struggling with an important, electronic question: What is the ideal display for my home theater? Many people have fought this debate, but I'll try to make clear some important considerations.

The most important detail to consider when deciding between a projector and a large plasma television is ambient light. A room with lots of windows presents a problem for a projector because every little bit of ambient lighting degrades the projected image. The ideal environment for a projector is one where you have total control over the lighting. If your home theater uses a projector, you are limited to using it when you can eliminate other light. A plasma screen can be used anyplace, anytime.

Assuming your home theater has blackout curtains, or exists deep underground; let's examine differences between a plasma television and a projector. One advantage of a projector is that you can get a much larger picture than is available in plasma. Projectors can produce images comparable to an 81-inch screen and larger. This just isn't possible with a plasma screen. However, plasma's have the advantage of not needing any amount of space. A projector must have a long enough corridor to project its image on the wall or screen. To get an 81-inch or greater image, you need a decent distance between the projector and the target. Second, a projector's image is dependent on more than the quality of the projector; you must be projecting onto a specialized surface or you lose detail. A top of the line HD projector with a very high native resolution would be wasted if you were just projecting the image onto a wall. You need an equally high quality screen with features such as a matte finish to eliminate reflection and glare. A plasma display requires no additional equipment.

Overall, a projector has the potential of creating a beautiful image, but it needs too much to work effectively. If you're creating a private movie theater with lighting control and an investment in a screen, mounting equipment, and blackout curtains, then a projector is your piece of equipment. For everyone else, I suggest a plasma television.

Choosing A Conference Room Projector

Choosing A Conference Room Projector
By Jim Gelder

When it comes to choosing a conference room projector, you probably want to run and hide! Thats because most of us dont know much about projectors to begin with and dont know the first thing about how to select one thats appropriate for a conference roomor any room for that matter.

Thankfully, theres the Internet. Within minutes, you can have all the information on choosing a conference room projector that you could ever want.

Sorting through all that information, though, can seem overwhelming. So its good to have some questions in mind as you do the research necessary to find the perfect projector for your conference room.

Some questions you want to ask are:

How difficult is operating the projector?
Is the projector portable or will it need to have a permanent mounting? Which type fits my conference room needs best?
What types of presentations will the projector be used for?
How much does the projector cost?
Does that cost fit my for buying a new conference room projector?
Is there a service contract available for the projector?
What is the repair policy for the projector?
Is the company Im thinking of buying the projector from a reputable and reliable one?
Will the projector require any special maintenance or periodic service checks?
Are any special supplies needed for the projector?
Is the size appropriate for the conference room?
If its portable, how much does it weigh?
Should I rent, lease, or buy?
Is the quality of the brightness satisfactory for the size of my conference room?
Do I need to save the receipt so that I can take the purchase off on my taxes?

These are just a few questions to help you on your way to purchasing (or leasing) a conference room projector. Just remember that cost does not always indicate quality. You can buy a wildly expensive projector that is all wrong for your needs. The opposite is true too: you can get a great projector that fits your needs for a moderate, or even small, investment.

The trick is in researching projectors and taking the time to read some consumer reviews that are easily found on the web. Before you do anything, though, have a budget in mind and have some idea of what youll be using your projector for. This will help guide your research and make it go more quicklyand be much more effective to boot!
