There are some very good explanations why many people are employing digital projectors in their property theaters today. The majority are small and light, require minimal setup and calibration (compared to a CRT), are quiet and have a bright, sharp image. But, there are lots of different digital projectors, ranging in price from around $700.00 to over $100,000.00. Which is the best for the specific application? Thankfully, the problem is changing, but many of the digital projectors marketed for home entertainment use are very just re-badged presentation units. Presentation projectors sacrifice good video quality for brightness. Brightness is significantly more important when giving a Powerpoint presentation in a lit room than the right color palate or the black level. The red on the pie chart looks great, no real matter what, as long as you will see it from the back row.
You want to choose one of the newer units that’s been truly designed for home entertainment applications. The specific technology employed for the imaging chip is not absolutely all that important, you can find great examples using all three of the digital technologies. Companies such as for example Sony, Runco, InFocus, Vidikron, Marantz, Benq, Panasonic, Sharp, Optima and Sanyo and some people all make great home entertainment projectors. The projector may have great black levels, to accurately reproduce detail in the darker aspects of the picture and give great contrast. Absolute brightness is not vitally important, if you don’t have a multi-use room without complete light control or you have lots of people over for sporting events. If you are entertaining many individuals for sports, it’s nice to own some light on in the space, so a lighter projector is advantageous.
Best Home Theater Projectors Under 300 can be found in numerous different resolutions. The lower the resolution, the smaller the screen you need to use before you will see pixel structure. Also, the reduced resolutions won’t support true HDTV. Most will display HD, but at a decreased resolution. The lowest end projectors routinely have resolutions of 800 x 600. The Texas Instruments Matterhorn chip is popular on budget priced wide screen projectors, and has a solution of 1024 x 576. Anything over a solution of 720 will allow for true HDTV. The TI number of HD-2 DLP chips has a solution of 1280 x 720. In April of 2005, TI announced new DLP chips with 1920 x 1080 was ready for production, allowing for true 1080p resolutions. Projectors with this specific chip will begin shipping in Q1 of 2006. Blu-Ray Disc has stated they will support 1080p, so by late 2006 you will have commercially available 1080p content besides Microsoft’s WMHD discs.
Another very important facet of home entertainment projectors is the interior video processing. That is one of the primary differences between good home entertainment projectors and presentation projectors. Digital projectors must display progressive scan images at the native resolution of the chip, so any interlaced signal, such as for example 1080i HDTV, must be de-interlaced and then scaled to the native chip resolution. Poor quality video processors, weather in the projector or external units, cause all sorts of video artifacts that can get in how of a satisfying video presentation. This subject alone is too thorough for this information, as entire texts have been written on the subject. However, one common video artifact is “jaggies” where diagonal lines are jagged rather than straight. Another annoying artifact due to poor video processing is moire ‘. This is a pattern viewed as alternating light and dark lines that change position since the image moves.
It is in addition crucial to be sure your projector supports the HDMI or DVI with HDCP copy protection to permit you to connect a HD-DVD, scaling DVD player or Blu-Ray Disc player. These units will only allow maximum resolution on a present that’s an electronic video input with HDCP copy protection. As time goes on, cable TV and satellite providers may restrict the maximum resolution to their digital outputs too
