This article presents the author's opinion on purchasing television technologies, such as liquid crystal displays (LCD), plasmas and cathode ray tubes (CRT), as well as new thin-tube technology--surface-conduction electron displays. Even before purchasing a high definition television (HDTV), the collective glare of the displays in my home could serve as a beacon for incoming aircraft . They include two LCD desktop-computer screens, two desktop CRT, one notebook LCD and one out-of-service iMac with a built-in CRT. Over the past 20 years, 12 to 15 monitors have passed through this place going back to the days of single-color green phosphor. We also have five CRT-based televisions and a new digital-light-processing rear-projection unit I just bought. When searching for an HDTV, I suggest that you judge the candidates on the quality of the image and viewing experience. And view the candidates outside the retail store so that you can be sure of which format you are looking at. Also, remember that retailers try to seduce customers with alluring videos, such as snowboarders doing flips down a snow-capped mountain. Other variables, such as size, weight and budget, are important, too. Physical limits and frugality are important, but that should not even begin until the picture of the television becomes clear.
