LCD monitors are getting bigger and bigger so to make sure you are getting the right one for your viewing space you need to check several factors before just going out and buying the biggest or least expensive monitor. There are also a lot of terms used to describe the different models and you should understand what each is before making a commitment to buy.

The size of your monitor will be measured on the diagonal from the bottom lower corner to the opposite top corner. Some may give actual length and width measurements but be wary as these can be estimates or rounded. You want to look at the actual screen size when looking at the measurement, so the actual TV may be larger than this given number.

The number of pixels in each direction is also important and this is known as the aspect ratio. This ratio tells you how many horizontal pixels they are per vertical pixels. Common aspect ratios is 4:3 while high definition is 16:9. The latest HDTV are ultra wide screen that has a ratio of 2:1. Where you place your TV and then view the screen will affect this ratio.

Aspect ratio is another important factor and most high definition monitors will have a 16:9 ratio. This tells you how many pixels there are horizontally versus vertically. So for every 16 pixels horizontally there are 9 vertically. Non high definition sets will have a 4:3 ratio while the newest ultra wide screens have a 2:1 ratio.

One of the biggest marketing tools used for LCD monitor is the contrast ration which can be difficult for the customer to understand. This basically finding the difference between the brightest spot on the screen and the darkest potion of the screen.

This measurement does vary throughout the monitor so the given number will be the highest contrast ration found on the TV, so it will not apply to the whole screen. Basically this means that the whites will bright and black very dark.
