What they are
A monitor or a display is an electronic visual display for computers. The monitor comprises the display device, circuitry and an enclosure. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) thin panel, while older monitors use a cathode ray tube (CRT) about as deep as the screen size.
Info on computer monitors
A computer monitor is an essential part of the machine. A computer monitor displays the output from the hard drive, video card and CDROM. Without a monitor, a computer is not operational. There are several types of monitors similar to a regular television. Flat-screen monitors with enhanced technology make it easier for users to install the device onto their computer. These monitors have replaced old tube screens that take up more space and are harder to install.
Resolution adds to the crisp, detailed display of images through monitors. Resolution is measured in pixels. Pixels are the tiny dots that display the image to the viewer. The more pixels, the higher the resolution and the better the detail of the graphics. High-resolution monitors are dependent on video cards for the best detailed images.
Contrast and Brightness
Contrast and brightness defines the light and dark settings of the monitor. Again, this is important for gamers who need more defined images. People who only use a computer for desktop applications don't need to spend more money on contrast and brightness.
Cables and Connections
The connection from the monitor to the computer uses a specific cable. The cable comes with the monitor. The other side of the connector cable is usually color-coded on the computer so that users know where to attach the cable to the motherboard. Additionally, a monitor comes with a power cable. These two cables are the only wires needed when installing a new monitor on a computer
