A viewsonic tv monitor is a computer monitor that can also function as a tv even with the computer off. It works like a regular monitor that can be switched over to a tv at the press of a button.
The main difference between a computer monitor and an LCD TV monitor is the pixel density, which is nearly twice as high on a computer monitor. This is the main reason that a computer monitor is more expensive. In addition, most computer monitors have a 16:10 aspect ratio, while TV monitors have a 16:9 aspect ratio.
Computer monitors have higher resolution (more lines or pixels) than television monitors (screens or tubes). Computer monitors also have the ability to "address" (pinpoint and turn on/off or color) every pixel (single dot of color on the screen). Television monitors do not have that precision.
