An electronic video projector provides the giant screen without the big TV. Projector advancements came quite a distance recently with absolutely no compromise in quality what this means is they now look better then ever and also have eliminated many past problems and are now actually affordable meaning the regular buyer is able to take on a HDTV projector for any reasonable price.
Stuff you will need:
Your financial allowance
Which space /room will the projector be situated in
Step one
The very first thing you will need to choose is what type of projector would you like. The two most common and many affordable technology is LCD and DLP. Some sensitive people may experience an effect which is refereed to because the "rainbow effect" which is unique to single-chip DLP projectors. So you may wish to seek for a demo from the unit first. Your best bet is simply too look for a local sound / home theatre store nearer your home to examine both technologies top notch.
LCD projectors produce richer color dynamics for better results in rooms with ample ambient light. DLP pixels are far less visible on the screen and the projector is actually smaller when compared with an LCD.
There is also a third technology called LCOS which can produce truly amazing video and is able to surpassing either LCD or DLP, however the prices are also extremely high. By 2010 prices should start to decrease as production be efficient.
Step 2
Take measurements of the space or room the projector is going to be meant for as well as identify the throw distance - the distance from the projector installed on wall / ceiling towards the location from the screen.
This throw distance will be associated with the throw ratio each manufacture identifies for a projector, meaning the distance the projector must be from the screen to produce a certain size image.
Step three
The following consideration will be: Resolution and Brightness. For brightness, you will have to determine how many lumen's your projector ought to be. This could vary from hundreds, to multiple thousands. For home theatre use brightness isn't as important as resolution. For resolution, you will want to match the resolution of the projector to your signal format you'll be displaying, if you plan to mainly concentrate on HDTV format a WXGA projector will probably be your most affordable selection.
Step 4
Chances are you will need a projector having a contact lens. Basically, a zoom lens quantity of 1.4 would translate to 40%. You most likely want a projector which has a decent sized zoom rate of at least 50%. This makes things a lot easier when installing your projector and making the ultimate adjustments. Additionally, it implies that you can place your projector closer to the screen in a tiny room.
Now that you know what you're after better, my advice is to look around a little. Stick with well known companies, as these supply the highest quality projectors in the best money saving deals as well as offer the best warranty deal. Check out major retail stores to visually compare projectors, or shop online to get the best deals.
