i am in the process of getting a new computer i would like an LCD monitor but i have 2 little kids who will use it age 2 & 4 and they like to put their hands on it and touch it. should i stick with the CRT for now or is the LCD monitor going to handle this abuse also is their any protective covers that can be placed on the lcd monitors, any help would be appreciated thanks.
Unless you plan on staring at spreadsheet 8hrs. a day, I would not purchase an LCD. The only areas an LCD supercedes a CRT are; they consume less energy, take up less space, may reduce eye strain when used for extended periods and let's not forget, they look much cooler than a CRT. Most experts agree a CRT performs better than an LCD when it comes to video and photo editing and games. Some people will argue the "ghost" problem with LCDs is no longer a problem, but a CRT is still considered better choice. The screen on a CRT is easier to clean than an LCD, but you can purchase a glare filter and place it over an LCD to ease cleaning if you must have one. The biggest reason however not to purchase an LCD is this, if you plan on ordering your monitor with a new Dell, a 18' LCD will cost you 385.00 more than a 19' CRT. Even a 17' LCD will cost an additonal 250.00 when compared to a 19' CRT. My advice to you is buy the CRT and use the cash to upgrade your systems memory, CPU, HD or video card.
CRT type monitors are the traditional monitors that we have been using for years. LCD type monitors are based on a newer technology and are becoming very popular, mainly because they have great space and energy saving advantages over CRT monitors.
One of the biggest advantages of LCD monitors is that they are compact and lightweight. An LCD monitor is based upon a very thin screen as opposed to the bulky tube of a CRT monitor. This means that not only do they take up less of your desktop space, they can also be used in many places where a larger CRT monitor can not fit. Shown here, a 12.1" LCD monitor with a stand takes up only about one-third of the desk space of a typical 14" CRT monitor.
Thanks to advances in LCD technology, color flat panel LCD monitors are now available that are comparable in screen size to traditional CRT monitors. Shown here, a 12.1" LCD display (left) has only a slightly smaller viewing area than a typical 14" CRT monitor. Newer, larger LCD monitors are also appearing that have 15", 17", and even larger screen sizes that are comparable to the largest CRT monitors. One thing to note is that LCD monitors are typically sized by their actual viewable diagonal measurement, but CRTs typically are not. For example, the viewable area on a 17" LCD monitor will typically measure 17" diagonally, but the viewable area on a CRT monitor will typically only measure 16" diagonally.
Most CRT monitors are capable of displaying unlimited colors. Some LCD monitors are only capable of hundreds or thousands of colors, but many of the newer LCD's are capable of unlimited colors.
An important issue with LCD monitors is resolution. CRT monitors are usually capable of displaying multiple video resolutions, each with the same quality. LCD monitors, however, usually has what is called a Native resolution, or the resolution that it displays best. The native resolution is generally the highest resolution that the LCD can display and this is the display resolution that will appear the crispest/sharpest.
Typically, brightness is not a concern with CRT monitors. LCD monitors are backlit and have different levels of brightness. The brightness rating for an LCD monitor is commonly referred to as 'nits', and commonly range from 70 to 250 nits. The higher the nits, the brighter the display.
Another issue with the LCD monitor is the viewing angle. A CRT screen can be looked at from a very wide angle, practically from the side, but an LCD monitor typically has a smaller viewing angle, needing to be viewed more directly from the front. From the side, the image on an LCD screen can seem to disappear, or invert colors. Newer displays that are coming out have wider viewing angles so this is not as much of an issue as it has been in the past.
Power Consumption and Radiation Emission
Besides being compact and space saving, LCD displays offer several other benefits. For one, LCD monitors consume much less energy than CRT monitors. This makes the LCD great for laptop and portable computers. Secondly, CRT monitors are known to emit harmful radiation, whereas LCD monitors do not.
CRT monitors are generally more affordable than LCD monitors. In the past LCD monitors have been very expensive but their costs have come down quite a bit in the last 1-2 years. One thing to consider is the up-front cost versus the long-term cost. A CRT monitor will cost less up front but will use more energy than a flat panel monitor. An LCD monitor will cost more up front but will conserve energy in the long run. The energy savings may not be much for an individual user, but if you are looking at a corporate office where 50 displays are in use, the energy savings might be more of an issue.
