Monitor critical terms

a. Screen size: Screen size is the length of the diagonal of the screen, measured in inches. At this time, the monitor 17 "(inches) become standard options than the size of the monitor 14" or 15 "which are widely used in the 90s era. However, do not close the possibility to choose size over 17 ".
b. Resolution: the resolution is the number of pixels contained in the image. The greater the resolution, the image will be shown more detail. For example, a monitor with a resolution of 1280 x 1204 pixels means that there are 1204 lines created from top to bottom and each line consists of 1280 separate pixels.
c. Refresh rate: This is the number of times an electron gun firing electrons at the screen. Refresh rate is measured in Hertz (Hz). Instead, the monitor has a refresh rate of 72 Hz or higher. Low refresh rate can cause fatigue in the eye.
d. Dot pitch: This is the density of picture elements called pixels or dot pitch. The more pixels the meeting, the more smooth and sharp display generated by the monitor. Instead, select a monitor that has a dot pitch values less than 0.28 mm.
e. Pixel response rate: This is the amount of time it takes a pixel to be active or not. In general, the pixel response rate is measured in units of ms (milliseconds). The smaller the average time, the better the image quality LCD display.
f. Dead pixels: This is the pixel located somewhere on the screen does not change the color images displayed when a different color. Dead pixel is one problem that often occurs on the LCD monitor. The characteristics of LCD have dead pixels is by paying attention to every part of the screen with color display plain white and black colors. Make sure that no color or a color shown left is not appropriate.
g. Luminance: This is a term that indicates the brightness of the LCD monitor owned. Luminance is measured in units’ candel or can be called nits. The bigger nits owned LCD monitor, the more good and bad of a picture seen. Range owned nits LCD monitor typically is 170 nits and the upper-class LCD monitors ranging up to 300 nits.
h. Contrast ratio: This is the difference between light and dark areas on the screen. Usually ranging from 200:1 to 500:1. in general, the higher the contrast ratio which is owned by the LCD monitor, the better the quality of images displayed. Large contrast ratio is recommended around 300 to 500.
i. Viewing angle: this is on the LCD monitor is divided into two: the horizontal viewing angles and vertical viewing angles. The greater the angle of the LCD monitor is owned, people will more clearly see the text or images on the LCD screen when used for presentations. Today, manufacturers are always improving the quality of the LCD monitor viewing angles to produce LCD monitor.
