You've already made the decision to establish a home theatre. You have the room designed to suit your desires and you've decided on a source for a HD source. Still, it does go through your mind on what might be your best choice for a home projector. The options are between a LCD unit and a DLP model, and possibly on how best to situate it.

Hopefully this write-up will provide you with some ideas to aid in your choice.

What is High Definition?

In short, 720 pixels PSI is the lowest resolution to be thought as HD (480 is the number for standard resolution). Projectors (and televisions) that are below that 720 pixel point (but superior to 480) are best described as "enhanced definition" and should only be thought of as good enough for watching DVDs or regular definition (free to air) TV.

The selections available for a High Definition projector would be those that produce 720p, 1080i, and 1080p. The "I" and "p" stand for the scanning mode (interlaced or progressive). Progressive scanning is the more developed of the two, so a 720p projector would be as good as a 1080i model.

Home theatre projectre arrangement

You might have already decided on the location to have your projector unit established. It might be connected to a wall/ceiling mount, or perhaps set on a low table (just bringing it out when you want to utilize it). Now the fun begins in making the improvements so that projected picture is properly established with the viewing surface.

Keystone correction is typically used to make the adjustments for your projector. This task allows for your unit to be placed vertically or horizontally off from dead center of the screen. Some projectors do give automatic keystone correction, but manual could be more to your liking. There is some corrupting of the image at the boundaries in using keystone correction but it's barely noticeable.

If your wallet can handle it, possibly you should check into a home theatre projector that utilizes lens shift correction. This is a more reliable way to make the alterations for where you establish the model, and the image doesn't undergo the edge degradation that you might experience with keystone correction.

It is hoped that this information has been of aid to you in making your selection on what to seek in a home projector to fit your home theatre requirements.
