Lcd monitors are not the same size as Crt monitors. Lcd monitors are indeed larger for the same sized Crt monitor! Monitor measurements are measured diagonally. Since the coming of the television, this has been the industry suitable for screen measurements. When computer monitors hit the scene, the estimation became the diagonal estimation 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 colse to your photograph 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 estimation 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 photograph to the upper right hand corner is indeed 17.25 inches, or in other words, only .25 inches larger than 17 inches, if the monitor estimation were the actual viewing screen this 19 inch monitor would only qualify as a 17 inch Lcd monitor. This is where the Lcd estimation comes in.
Lcd Computer Monitor
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 small known glich in monitor measurements is how the diagonal estimation of a widescreen monitor reduces the ample height of the monitor which in turn reduces the actual size of a suitable 4:3 to a smaller size. Example: If you purchase a 32 inch widescreen Tv and watch a suitable broadcast movie in it's former format, you in essence are watching a 26 inch television. A more in depth look at how this estimation effects the full screen format, please read my Widescreen article. [http://www.thegourdreserve.com/dailysaleswidescreen.shtml]
