What should be minimum Lumen specification for a home theatre LCD projector? I want to set up projector based home theatre system. Please advise me on most basic requirements such as Lumens of projector, RMS watt of the home theatre 5.1 channel. Also advise the best brand among SONY, HITACHI, SHARP, PANASONIC, HP.
These are all subjective questions that also depend a lot on your requirements. Lumens: First off, some projector manufacturers are more dishonest than others about their lumens ratings, so equal numbers don't always produce equal brightness. If your "theater" room is always well darkened & the screen is not too large, you might be able to get away with 1000 lumens. If you may have significant amounts of room light & or a really big screen, you might need 2000 lumens or more. RMS Watts: This is VERY dependent on your needs. Room size, and loudness preferences and speaker efficiency are important. You might need 15 Watts or 200 Watts or more. A 200 Watt amp is only 10 dB louder than a 20 Watt amp. That's a substantial difference, but not huge. Brand: Go shopping and let you eyes & pocketbook answer that question. It wouldn't hurt to read thru some video magazines first. For example: Many projectors don't do blacks or near-blacks well. Bring a DVD with dark scenes with you when you go shopping.

Beamers, also called multimedia projectors, are today more popular than ever. Actually, a lot of individuals have beamers inside their house to enhance their cinema viewing experience manifold. In case you are thinking about buying one of them, here are some factors to consider so you can identify the right beamer for your requirements. Projector brightness Brightness in projectors is rated in lumens: the greater the lumen value, the better the projector. For the most part, the more light there is in the room, the brighter the projector must be. Because of this, a home theater projector with less than 1000 lumens can already develop exceptional picture quality as it will be utilised in a dark room. But, in case the identical beamer is required outdoors at broad daylight, the projected image may look pale. Another general guideline is that the more detailed the picture you wish to project, the brighter the projector must be. In such regard, if you need to project text, graphs, or any other comprehensive materials you will need a beamer with no less than 2000 lumens. Resolution On the subject of projector quality, the larger the pixel number, the clearer the projected picture will likely be. There is a selection of resolutions available, and as you move up this spectrum, so does the price. SVGA and WVGA are the two lowest resolutions available on projectors, and they are popular because, you guessed it, they are within everyone's budget. Full HD beamers, also called 1080p beamers, and 2K beamers, comprise the top two rungs in terms of resolution. Naturally, they are the most expensive. If you would like to purchase a projector that could show sharp images but do not wish to shell out a lot of money, try to find models that have XGA, HD2 or 720p, and WXGA resolutions. Having said that, also keep in mind that it is advisable to match the projectors resolution to the sources resolution. If you've got a laptop computer with XGA resolution, and you use a HD beamer or 1080p projector, you still will likely not get the sharpest and cleanest image. Technology You can get three types of projector technology, namely, LCD, DLP, and LCOS. DLP beamers are preferred in terms of beaming videos as the images they produce are softer. LCD projectors however do a better job at showing data or in depth media since they can produce crisper images. LCOS are not as sought-after given that they are more expensive and dead pixels are more noticeable on them as compared to other technologies. However, they can achieve brightness comparable to LCD, and provide smooth, film-like image like DLP. Projector technology is improving over time, in fact, nowadays, you can already find full HD Beamers with 3D capability. Click here for additional info on these brand new projectors.
