Now that you’ve chosen what size HDTV to get the next question is what type of technology you should look at.  Older CRT analog televisions were all based on the same basic technology, but now you have a potentially confusing array of choices: LCD, plasma, DLP, LCoS, and D-ILA.  LCD and plasma are both flat panel technologies that can be mounted on walls.  If you’re looking for an HDTV less than 42 inches then LCD is probably your best choice.  Plasma is a better choice for HDTVs over 42 inches, as current LCD units get very expensive in larger size formats.

I just pre-ordered the new Samsung HLS-5087W 50 inch rear projection DLP HDTV.  Many believe that DLP technology offers the best price/performance in the 50 inch plus category of HDTV today.  Sony has made a large investment in LCoS technology which it brands as SRXD, while JVC brands their LCoS line D-ILA.  LCoS (Liquid Crystal on Silicon) is most similar to DLP (Digital Light Projection) technology, however many believe the DLP camp has made faster progress on reducing manufacturing costs to offer consumers a better price/performance ratio.  While rear projection DLP HDTVs lack the flat panel appeal of LCD and plasma units, they are much lighter and have far less depth than the CRT televisions of the past.

You’ve chosen the right size and technology for your new HDTV, and now you’re trying to understand what is 720p versus 1080i versus 1080p.  Let me help you out here – don’t bother getting a 720p today.  I’d recommend at least a 1080i, better yet a 1080p.  My new Samsung is both 1080p input as well as output.  In order to understand what all of these strange numbers mean, well, you’ve have to wait until my next article.
