Finding room on a desk for a computer monitor is challenging. Today, more people are switching to thinner liquid crystal display, or LCD, monitors that take up less desk space and use less energy. Understanding the benefits of LCD monitors can help you decide if they are the right choice for your computer. Here are a few facts about LCD monitors to help you get started.
LCD or CRT: Before LCD monitors became affordable, most computers came with cathode-ray tube (CRT) monitors. CRT monitors have the same technology found in tube TVs. CRT is still favored by professional photo editors because of its color purity. LCD monitors are lighter and take up less space, however. The resolution of an LCD monitor is adjustable as well, allowing you to display multiple resolutions on the computer monitor depending on your task.
Energy efficient: LCD monitors require less energy than other types of computer monitors. The energy used to run an LCD monitor can be as much as half that required to run a CRT monitor. If you are an occasional computer user, you may not see the difference in your electric bill, but for people who have their monitors running for several hours a day this will save them a lot of money.
Cooler temperatures: CRT monitors produce large amounts of heat while operating. LCD monitors, however, produce much less heat when they operate. This can be significant if the computer and LCD panel are housed in an enclosed space. Excess heat can damage or degrade computer components. LCD monitors are also less likely to be fire hazards.
Computer vision syndrome: Using an LCD monitor can help reduce the risk of computer vision syndrome, a condition that causes headaches, blurred vision, dry eyes and neck pain. Because LCDs have less glare and are flicker free, users who use LCD monitors are less likely to develop these health problems.
Drawbacks for LCD monitors: Despite the advantages, LCD monitors do have a couple of potential drawbacks. One is the dead pixel problem. On some monitors, one or more pixels used to create the image on the screen stop working. They cannot be fixed, so a tiny black dot appears on the screen. This infrequent problem can only be fixed by replacing your LCD monitor. Another issue is the viewing angle. Viewing early model LCD monitors at an angle can make images seem distorted. Newer versions of LCD technology have addressed this problem. If you usually view your monitor head-on, this won't be a problem at all.
