Projection TV Buyer’s Guide

One of the advantages of projection TVs over traditional CRT TVs is that they can provide a bigger picture. Although the technology behind the two systems is very similar, the main difference is that projection TVs create a small picture, like a CRT TV, and then using a beam of light project the image to a much greater size.

In this expert guide the different types of projection TVs are explained as well as the features you can expect from the projection TVs within the various price ranges.

Available types of Projection TVs

There are two types of projection TV setups available on the market, front projection and rear projection.

Front projection systems are similar to those found in movie theaters. It consists of a projection unit and a separate screen. The projection unit projects the pictures onto the screen using the beam of light.

Rear projection systems are completely different, in that their technology is similar to CRT TVs. The projection unit and the screen are contained in a single television unit and the projector displays the image onto the back of the screen. Although these systems can have very large screens, even bigger than LCD TVs – they are bulker and heavy because the technology behind them is similar to CRT.

Note: This expert guide will only discuss rear projection TV sets, including the specifications and options available within the different budget ranges.

Important specifications

When shopping around for a rear projection TV, it is important to keep in mind the following specifications.

• Aspect ratio
  The aspect ratio refers to the shape of the screen, depicted as “width:height”. Most rear projection TVs have an aspect ratio of 16:9, in other words are widescreen.
• Resolution
  The rear projection TV specification will display the resolution as a figure like 1,920 x 1,080. This indicates the physical number of horizontal and vertical pixels within the screen display matrix.
• High definition
  Not all rear projection TVs are high definition enabled so if this is an important feature for you, look to see if the specification states HD-ready or HD compatible.
• Connection points
  A rear projection TV must have at least one SCART socket, while most also offer S-Video as well. Some may even come with USB hubs so that you can connect peripherals like digital cameras or even a PC. High definition Plasma TV’s will also have a HDMI connection.
• Viewing angle
  As rear projection TVs use a similar technology to CRT TVs, their viewing angles are not as great as LCD or Plasma TVs. Always check the glare and the angles when viewing rear projection TVs.
• Contrast ratio
  A high contrast ratio means that blacks will appear deeper and whites will appear brighter on the screen. As a rule of thumb DLP sets generally have a very good black level.

Entry level budget

Rear projection TVs are cheaper than Plasma TV and it is possible to buy a set for under $500 but the picture clarity and color display is usually poorer than the more expensive television sets.
