What To Consider Before Buying A Rear Projection HDTV


Though most people today prefer flat-panel TV sets, the less-known rear projection HDTV is a great alternative if you are one of those who are not really particular about very shallow profile or wall mounted TV sets.

Rear projection TVs are definitely a lot bulkier than the latest DLP, LCoS and LCD sets. Also, there may be some change in the quality of image that you get with such a TV set. In this article, we tell you the things you should consider before going in for the purchase of a rear projection HDTV.

Picture quality

Not many people are aware that many TV screens which measure more than 42” diagonally are rear-projection TVs. They project an image inside a box and display it using lenses and mirrors on the inner surface of a highly translucent screen. Originally, these devices used CRTs to create the image.

The rear-projection HDTVs you find in the market today take full advantage of their hi-def digital quality, giving users a fantastic experience, as regards both sound and picture. Built-in HD tuners available now are pretty much standard and all these devices also include tuners for analog broadcast and cable TV too, with or without a set-top box.


Today, the customer is truly king and he has a variety of options to choose from, as regards the specs of his chosen electronic device. You have to particularly look into the specs of the rear-projection TV before zeroing in on one of your choice.

Here is what you should look for:

  • Aspect ratio

The aspect ratio, or the relationship between the screen width and the screen height, is probably the most important feature. Normal TV sets have a 4:3 ration. But wide-screen models these days come with a 16:9 aspect ratio. HDTVs have a wide screen, which gives you amazing clarity picture-wise.

  • Resolution

Non-CRT displays have fixed-pixel arrays, meaning, they consist of rows and columns or picture elements that turn on and off to offer the necessary picture effects on screen. CRT display resolution, on the other hand, can adjust itself according to the normal and hi-def formats. A display becomes hi-def if the wide screen gives a total pixel count of about 1 million.

All the latest rear-projection TVs are actually HDTVs, so you will have great resolution with most of these sets.

  • Video inputs

You have to also look into the amount of video inputs your chosen set is offering you. Video inputs include a composite video input, S-Video, Component Video input, VGA, DVI and HDMI inputs.

The more your video inputs, the more variety you have to choose from, as far as video-viewing formats are concerned.

Among these, the HDMI input of course offers highest quality content. You may even think of buying an HD DVD or Blu-ray Disc player to go with it, as an extra add-on.

  • Setting up viewing angle

You should know that rear projection HDTVs will lose their apparent brightness when you move away at an angle from them. Also, the horizontal fade is much more pronounced than the vertical one. Of course, chances are that you are not going to change your position once the TV is fixed in its place, but you should look into this matter before actually installing it somewhere in your home.

  • Built-in tuners

Most of the rear projection HDTVs available today, come with built-in tuners for both analog transmission and cable TV as well. But only a few sets offer support for handling premium channels. So make sure of this aspect too, before making your final purchase. In case you want this feature, you may have to shell out some extra money for it.
