Which technique is the best among lcd,plasma,projection,hdtv in terms of clearest picture?
Plasma and LCD will always have a better picture than projection. The only benefit of projection is that you can have very large screen sizes. Deciding what to choose between plasma and LCD is a matter of personal preference and you should check both out at your local store. But in general terms plasma is better for “high speed” programs like sports, but LCD looks better in daylight or bright lighting.
