Top 5 Budget Full-HD Projectors.

The shiny sleek panel TV’s are increasingly affordable these days but they’re still no match for good old theater light projectors. They also come for around the same price. The latter not only delivers the closest theatrical experience comparable with a full cinema experience, but is also more economical to set up as the screen size scales in excess of 60 inches. Here are the five value-for-money projectors to get you started without breaking the bank, from the rivaling DLP, 3LCD and SXRD projectors.

1. BenQ W1000


The good: Small and transportable; natural colors and decent blacks after calibration.
The bad: Noisy fan; rudimentary installation options; default picture settings look terrible.
The bottom line: The BenQ W1000 DLP projector may be a value-oriented 1080p beamer, but will give you pretty good picture quality after calibration.
2. Epson EH-TW3500

The good: Flexibility of placement; easy to install; can produce stunning images.
The bad: Looks best after proper calibration; some motion blur; bulky.
The bottom line: The Epson EH-TW3500 rewards the viewer with sumptuous, bright and highly involving images and is decidedly competitive at this price.
3. Mitsubishi Electric HC3800

The good: Compact size; impressive HD images; great blacks and natural colors; value for money with long lamp life.
The bad: Prefers permanent placement; only one HDMI input; dust magnet.
The bottom line: The HD image quality of this Mitsubishi and its longer lamp life are key to this projector’s appeal. If you can forgive a few minor shortcomings, the HC3800 is an excellent choice among the current affordable 1080p crop.
4. Optoma HD20

The good: Small and easy to install; good image quality; value for money.
The bad: Noisy in “Bright” mode; slow HDMI input detection; blacks could be deeper.
The bottom line: Value for money, compact dimensions and easy to get up and running out-of-the-box, there’s a lot to like about the Optoma HD20.
5. Sony VPL-HW15

The good: Some of the best blacks and contrast levels; great picture quality; straightforward setup.
The bad: Lacks some positioning flexibility; pricier than a lot of the competition; relatively expensive to run.
The bottom line: The Sony VPL-HW15 may cost you more than a budget 1080p, but the images it presents make this beamer well worth the money.
Our pick: Sony VPL-HW15

Sony’s 3D Head Mounted Display

Sony is working on a futuristic head-mounted display that immerses the viewer in 3D video.The device, which is still only a prototype, was unveiled at a Sony news conference at the Consumer Electronics Show in Las Vegas.

Inside are two OLED displays that provide a high-quality, high-contrast image. A test of the prototype after the keynote backed up Yoshioka’s claims of a clear, vivid 3D image. The glasses required a quick calibration, so the images from the screens were correctly aligned to each eye, but after that they worked without a problem.

Sony has no launch date for the display, which is still being developed. Two years ago at CES, Sony showed off a prototype head-mount display that showed 2D images. That device still hasn’t come to market. It wasn’t the only 3D prototype on show. Sony also had no-glasses 3D televisions and a Blu-ray Disc player with 3D screen. Just like the head-mount display, Sony says the no-glasses 3D TVs and Blu-ray player are prototypes.

There’s no word on when they might be available. For more news and updates subscribe to Alvistor.com

Toshiba REGZA Glass-Less 3D TV

We all know that an 3D TV requires an special type of glasses to wear to experience Full 3D. Now Toshiba has found an solution to this problem. At CES Toshiba unveiled its new range of 3D TV’s, were 3D can be experienced with out an y glasses or any sort of equipment.

With all the expensive technology and calibration needed for this method to work, delays could happen in the factory or issues could emerge after transportation in high seas and when installed at destination.

The glass-less TV uses an LCD shutter and lens added to the tradition LCD. Moving the shutter and magnifying with a lens, it shoots out 3D-like visuals to the viewer. Japanese TV manufacturers have admitted defeat to Korean manufacturers, and Toshiba has changed its strategy to ultra-highend products. The nine-channel, all-knowing, all-seeing and recording monster TV, Cell Regza, was quite successful even when priced at US$10,000.

Toshiba also had another surprise. It offered RZ Commander, an iPhone, iPad and Android app to control its TV, allowing you to use SNS to leave comments on programs you are watching in real time. The TV ships in December as announced by Toshiba.

Sharp’s New Yellow Pixel LED-lit-LCD TV’s

When I thought of the fact that an fourth yellow pixel TV coming from Sharp I just thought that, why would you need to change something that work soo perfectly on the present time. And they said that it would give more definition and depth to the picture and add more color to it. So I thought lets see and confirm it by seeing it when it comes out and finally it came out and we at Alvistor get’s to share about our experiences and thought till to the final conclusion “Do we really need an YELLOW pixel?”.

WHAT IS AN PIXEL:

The pixel is the smallest addressable screen element; it is the smallest unit of picture that can be controlled.” In TV’s it basically a pixel is defined to an certain color. There are three colors that it can be defined to like Red, Green and Blue. These three colors can be mixed in certain amounts to produce any color to display on screen. The more the number of pixels in the television screen, is the more definition in screen you can get out of your TV. This is the basic meaning that can be given to an pixel.

ABOUT THE TV:

  • Full HD 1080p (1920 x 1080) Resolution – with more than 8 million dots for the sharpest picture possible.
  • Quad Pixel Technology – featuring a 4 color filter that adds yellow to the traditional RGB.
  • UltraBrilliant LED system – includes a unique “double-dome” light amplifier lens and multi-fluorescents, enabling high brightness and color purity.
  • 120Hz Fine Motion Enhanced – for improved fast-motion picture quality.
  • AQUOS LINK™ – enables convenient control of AQUOS Blu-ray Disc™ player
  • AQUOS Net – delivers customized Internet content, Netflix and live customer support via an Ethernet connection, viewable in widget, full-screen or split-screen mode.
  • USB Photo Viewer with Music Player – enables enjoyment of high-resolution digital JPEG images and MP3 music files.

ADVANTAGES OF YELLOW PIXEL:

  1. An additional yellow pixel has an advantage of giving more light to the picture.
  2. It is good for 3D TV’s which actually need these kinds of light.
  3. Sometimes good picture.

DISADVANTAGES OF YELLOW:

  1. Pictures are highly saturated.
  2. The color Yellow looks like Orange sometimes.
  3. Every color looks too saturated by the pixel.
  4. After sometimes it felt like blinding after seeing some pictures on it.
  5. Color balancing way awkward.

CONCLUSION:

It is an good TV. But not an great one. Especially Sharp just made this TV to have some marketing hype and of course to stand out from the crowd. And the fourth pixel is such not a good idea at this time. Even the colors looked more saturated. It also has integrated internet TV in it which has an sloppy interface to it compare to its competitors. Finally what we guys from Alvistor decided that its not that good to spend your dollar on it. So we recommend that to skip this TV and invest on an anther useful LED or other display methodologies. If you don’t know the difference between for an LED and LCD check this link.
