LCD or CRT

Differences between LCD and CRT monitors

CRTs might be nearly gone, but they do have some advantages. For example, CRT computer monitors are considered better at displaying full-motion video, though many LCD screens now do a good job in that area. CRTs also work better at multiple resolutions (as opposed to LCD monitors, which are designed for one or two optimum resolutions), and can display more pixels than a comparable LCD screen. More pixels allow you to see more detail on the screen, and you'll be able to view more of a document or web page without scrolling.

Color fidelity is something that's of great concern to photographers and graphics pros, many of whom have long felt that they get truer color, for the most part, on a CRT. While some still are hanging on to their trusted older monitors, most are now opting for LCD monitors when the time comes to upgrade or replace. One reason is that modern LCD monitors -- especially high-performance models -- boast contrast ratios and display colors that rival the best CRT monitor has to offer. The other reason is that high-performance CRT monitors are no longer being made.

Finally, there's the viewing angle issue. If you've ever looked over someone's shoulder onto a laptop or LCD, you'll understand this problem immediately. The best view on an LCD monitor is always straight on. The primary user will get the best screen image. People who might be sitting to the left or right won't get the best color or clarity, and if they are sitting too far to one side, the image disappears from view entirely. Again, in this area, LCDs are improving, but CRT monitors still have the upper hand. CRT images look virtually identical from wherever you are viewing the screen.

CRT monitors are subject to screen flicker, hot spots and geometry problems, issues that are virtually eliminated in LCD technology. LCD monitors use much less power than CRTs -- about 60 percent less.
