LCD Monitor vs CRT Measurements - What You Should Know Before You Buy

LCD monitors are not the same size as CRT monitors. LCD monitors are actually larger for the same sized CRT monitor! Monitor measurements are measured diagonally. Since the advent of the television, this has been the industry standard for screen measurements. When computer monitors hit the scene, the measurement became the diagonal measurement of the tube itself, not the actual viewable screen. When you look at your monitor, there is a plastic box that houses your CRT tube and other components, but when you look at the front of your monitor, there is probably an inch or more of framework around your picture tube. This hides the rest of the CRT tube that is enclosed within the box.

Now take a ruler or tape measure, and measure the actual image you are viewing, measure diagonally, and you will see that the actual measurement is smaller than the monitors claimed size. For example, my 19 inch CRT monitor, measuring the actual image from the bottom left hand corner of the picture to the upper right hand corner is actually 17.25 inches, or in other words, only .25 inches larger than 17 inches, if the monitor measurement were the actual viewing screen this 19 inch monitor would only qualify as a 17 inch LCD monitor. This is where the LCD measurement comes in.

LCD monitors are measured by actual viewable area of the screen. They do not have a large rounded out tube beyond the screen, it is a flat panel of Liquid Crystals behind which are a series of tube lights that shine through the color crystals to illuminate your display. A 17 inch LCD monitor is 17 inches diagonally, a 19 inch monitor is 19 inches diagonal or about 1.75 inches larger than my example of the CRT tube.

Another little known glich in monitor measurements is how the diagonal measurement of a widescreen monitor reduces the overall height of the monitor which in turn reduces the actual size of a standard 4:3 to a smaller size. Example: If you purchase a 32 inch widescreen TV and watch a standard broadcast movie in it's original format, you in essence are watching a 26 inch television. A more in depth look at how this measurement effects the full screen format, please read my Widescreen article. [http://www.thegourdreserve.com/dailysaleswidescreen.shtml]
