This article by George Ou should help sort things out. He covers the advantages and disadvantages of:

Projection: Pro: price. Con: viewing angle.
Plasma:Pro: resolution, colour, viewing angle. Con: price.
LCD:Pro: picture quality. Con: expensive large size sets.

George also advises, bluntly, against getting suckered into buying so-called high end cables:

Consumers need to get the concept of "monster cables" out of their minds since they DO NOT apply to the digital world. There is zero difference in quality between the cheapest $12 HDMI to DVI cable versus the $100 gold plated "monster cable".

He also makes available some colour gradient graphics and explains how to use them in testing the colour quality of an HDTV.

This is a great piece for anyone in the market for a new HDTV, and it's especially useful for those of us that may be more than a little confused and/or overwhelmed by variations in HDTV technology.

Those of you thinking of running your PC through a 1080p set should be aware that you may not necessarily get to use all that extra resolution--even if you have the right high-end graphics card. For instance, the Sharp set we tested allows you to max out at only 1,280x1,024 resolution while the less-expensive Westinghouse LVM-37W1, along with Samsung's 1080p RPTVs and one series of high-end sets from Mitsubishi, accept true 1,920x1,080 resolution from a PC.
