LCD Monitors Vs CRT Monitors


Visitors: 188

LCD monitors and CRT Monitors have lots of positive as well as negative points going for them. These traits entice millions of consumers to buy them. The question is which one to choose? There are several pros and cons on both sides to consider. First, let's know the positive aspects of LCD monitors as compared to CRT monitors.

They use less Power. They also produce less heat, both when running and also when in standby mode. For example, a 15 inches LCD uses around 25 watts when operational and around 3 watts when in standby mode compared with an equivalent viewing area 17 inches CRT that uses 80 watts when operational and 5 watts in standby mode.

They occupy less space. They are also small, thin and weigh less.

They are highly adjustable. Many of their models can be rotated 90 degrees allowing you to view websites in portrait mode. They can also be mounted on the wall or on an arm.

They are free from flicker. That means they do not have lines that need to be scanned like in a CRT. They are free from VLF/ELF electromagnetic radiation emissions associated with the scanning electron beam required for a CRT. No flicker is equal to a lot less eye strain.

Due to the material of the liquid crystal display screen, less light is reflected at the user. This results in less eye strain. These displays have uniform screen brightness and the screen is covered with a flexible surface that is substantially less prone to glare compared to a glass covered cathode ray tube screen.

They are brighter than a traditional CRT monitor.

There is less distortion in the case of an LCD monitor. Using a direct digital input from the graphics card produces cleaner ‘output’. The monitor's perfect geometry means images are not distorted, which is a boon for graphic designers and the like.

Now let's have a look at the negative aspects of LCD monitors as compared to CRT monitors:

They are more expensive than CRT Monitors. You pay for what you get; former looks good and isgood for the eyes too.

In an LCD monitor, when the electrical current to one or more pixels does not operate properly, one or more cells are permanently aligned, resulting in a dead pixel.

They may be slim and sexy but they are also more prone to damage and screen breakage. They are fragile, so screen care is important.

They are most effective in their native resolution. They can only display information well at the resolution they were designed for. At any other resolution, image quality will suffer.

Pixel response time: In videos and fast-paced video games, liquid crystal display screens suffer from the ghosting effect. Some of them (low cost, low resolution) have pixels that respond too slowly for accurate video rendering, and some tearing of the video image can occur, which usually is not an issue for a CRT monitor.

Looking at an LCD monitor from an angle causes the image to look dimmer or even disappear completely. It gives better screen privacy because they cannot be clearly viewed from acute side angles. This also helps the user to maintain the alignment of his body with the screen.

They have good colour range but lesser than the latter. The colour accuracy of an LCD does not match with that of a CRT. For high end color graphics, CRT Displays can offer some advantages because LCDs can only display the colors available in the pixels and so they can have less of a color depth than CRT monitors.

In addition to some of the positives mentioned, many LCD monitors now incorporate other features to make them more practical. These monitors can now be found with integrated USB hubs, stereo speakers and TV tuners. They will continue to replace CRT Monitors as they are less expensive and the many benefits are realized by consumers but CRT monitors would not disappear all together as many situations require the performance that LCD Displays currently can not provide.
