Well done Kim Komando of USA
Today. Well done. Projectors can be a great option for some consumers that seeks a HUGE screen but have space
requirements. (and a budget) But they can be daunting because of the huge price range ($800 - $15,000) but Kim
did a great job laying out most of the things you need to look for. She goes over LCD, DLP, and CRT options and talks
about how important lumens is. Kim even talks about their Achilles heal: the pricey bulb.
Ms. Komando covers most of what a person should look for but forgot to cover the different resolution. A lot of lower priced units do not produce a high enough resolution to be considered high-def. They will display the same image, but will do so by lowering the resolution of the signal to its native resolution. You can find good inexpensive projectors for under a thousand that does have a good resolution however; just stay away from the 800x600 units if you want to use it for HDTV.
Check out Kim's guide to projectors if you have any questions about these mini-giants of TVs.
