A computer monitor is an electronic device that shows pictures for computers. Monitors often look similar to televisions. The main difference between a monitor and a television is that a monitor does not have a television tuner to change channels. Monitors often have higher display resolution than televisions. A high display resolution makes it easier to see smaller letters and fine graphics. The CRT monitor.
I think you're looking for is the term resolution. Computer display (or monitor) resolution is usually expressed in numbers of columns (vertical) and rows (horizontal) pixel counts. A pixel is generally the smallest addressable element in a display screen and may be composed of three or more color-producing sub-pixels.For example, my notebook's LCD panel has a resolution of 1280 x 800. A larger, higher resolution notebook display might have a resolution of 1440 x 900.HD 1080 format monitors or televisions often have resolutions of 1920 x 1080, where 1080 is the number of horizontal lines.he width-height ratio is 16:10 instead of 4:3. For example, WXGA is 1200x768.   Most laptops sold today (2008) have a measly XGA (1024x768) display. Top-end laptops may have as much as QXGA, or quad-XGA, which is double the width and height (in pixels), or 2048x1536.
