Traditionally, CRT (Cathode Ray Tube) monitors have been used for desktop computers. However, LCD (Liquid Crystal Display) monitors are now more and more popular. It's easy to see why: LCD monitors are affordable now, easier on the eyes, and they're slim/portable and of high quality plus laptops also use LCD screens.
Before you buy a LCD monitor, you will need to know the following things:
1. Your Budget
Of course, this is the very first thing you will need to consider, and once the budget is fixed, you narrowed your choices, and you may focus on a few models.
2. Your Requirements
If you're a graphics professional, you may prefer a CRT monitor because they are said to show more realistic colors. However, the latest high-end LCDs can also give equal color quality (Well, of course, you’ll have to pay much more for this than for a regular LCD monitor ).
If you are a demanding gamer, you may need a comparatively larger screen LCD monitor with a better response time, you won’t like the tails of the mouse, will you?
If you just want a computer for on-line surfing or occasional gaming, a LCD is a good choice because the various pixels that you find on a LCD will have nicely defined edges. This gives sharp and focus letters on the screen better than a CRT monitor does. However, a high-end LCD in this case is definitely unnecessary since you will never have a chance to make use of its advantages.
3. Resolution
If you have a computer with a video card that supports a resolution of 1680 x 1050, while you bought a large LCD monitor with a 1920 x 1200 resolution, then you won’t have the pictures/videos fully displayed on the monitor, or the pictures will look much less clear or sharp.
Besides the 3 points above, there are also many other things need your attention:
Panel Size: In an LCD monitor, the panel size reflects the viewable area you can use. Again, the measurement is made diagonally from one corner of the screen to the opposite corner. LCD panel sizes now range from 15 inches up to 23 inches or even larger.
Defective (dead/stuck) pixels: A LCD panel display may have certain defective pixels (red/dead…). But this can be identified by turning the desktop background into a whole black.
Viewing Angle: One problem specific to LCD monitors is the fact that you cannot see what is displayed if you move off to the side of the monitor too much. A greater viewing angle is therefore typically better - especially if you need to show presentations to others on the LCD screen very often.
If you do not want to bother yourself with those technical details, there is also another good way to choose a LCD monitor: to read reviews and ratings, for example, consult product reviews in computer magazines or on the Internet. Many different companies put monitors through rigorous testing and really can help you to buy wisely.
