I like changes and that’s why I keep looking for various options. Recently I changed my old computer monitor from a LCD monitor and I know that it’s a constructive move. Let me explain you this in brief. Actually the ordinary monitors who are also known as CRT monitors have a major disadvantage. CRT monitors work on the basic principle of cathode rays and that’s why have a cathode ray tube. Even though there is a protective net which absorbs many of the cathode rays from coming out of the screen but still at least 40% of the rays still come outside. Whereas a LCD monitor has no such cathode ray tube because here the mechanism is totally different. It works on polarization of a liquid present in very minute cells present in screen. They get polarize and hence display is generated. It never affects eyes as there are no rays. That’s why I bought a LCD monitor for my computer and dumped the old one.
