Dot pitch is the distance between the centers of two same colour phosphor dots on the screen.

The image you see on a monitor is created by red, green and blue phosphor dots that glow when hit by an electron beam. The dot pitch specification for a display monitor tells you how sharp the displayed image can be. The dot pitch is measured in millimeters (mm) and a smaller number means a sharper image.

A lower-value dot pitch means a clearer image. However, very small dot pitches may also give decreased brightness and contrast.

It is screen reaction time, ie the time it takes for your screen to react to any command.

It refers to how quickly a pixel can change colours, measured in milliseconds (ms); the fewer the milliseconds, the faster the pixels can change, reducing the ghosting or streaking effect you might see in a moving or changing image. If you are an avid gamer and movie buff and intend to watch movies or play games on your PC, then you need to get a monitor with a good response time. The average RMS (response per millisecond) is 8. The really high-end monitors come with 2 RMS.

Higher response time better is the refresh rate.

It is the difference in light intensity between the brightest white and the darkest black on the screen. It helps in increasing the darkness of the screen.

Contrast ratio is measured as the difference between the brightest and darkest colors on the screen.

The higher the contrast ratio the greater the ability of a monitor to show subtle colour details and tolerate extraneous room light.

Pincushion control helps you adjust the sides of the screen to get better viewing.

Pincushioning is one of the most common distortions on monitors, where the screen curves inwards at the top/sides or sometimes even both. This control helps adjust this distortion.

This control helps you get a better and straight screen, which enables better viewing.

Low Radiation monitor is designed to minimise the radiation it emits.

VLF (very low frequency) and ELF (extremely low frequency) radiation from computer screens are a health concern, but their effects are not known as certain.

This is a health feature and protects the body from radiations emitted by the monitors that are harmful.

This is the digital video connection between your computer and your display.

DVI helps transmit video information faster to your computer giving your superior quality images. You will rarely find a CRT monitor that support digital signals, but the LCD monitors do.

DVI cable will help transmit the signals faster onto the display.
