Ive been doing searches in order to learn more about buying a tv.. DLP, LCD, HDTV RP.. but i continue to come across the CRT. Can someone tell me what is the CRT tv? And if someone has the time to give me a few pros and cons between the rp hdtv, dlp, and lcd. i will continue to use the search function in the mean time. thanks. PS i only need the definition for CRT and what type of tv it is.
