Specifications

Key factor for LCD monitor evaluation:

1. Resolution
The vertical and horizontal size displayed in pixels such as 1024×768. LCD monitors provide a native-supported resolution for high-quality effect while monochrome CRT monitors do not.

2. Dot pitch
Dot pitch is the measure of two adjacent pixels in the different distant between their centres. The tinier dot pitch size, the less granularity is provided and this leads to a shaper image. Dot pitch might be the same or different both horizontally and vertically.

3. Viewable size
The size of an LCD panel can be measured on the diagonal

4. Response Time
Response time is the minimum time required to alter a pixel’s brightness or colour. It is split into rise and fall time. As for LCD monitors, the measurement is gtg (gray to gray) or btb (black to black).

5. Refresh rate
Refresh date is the number of times in each second that the monitor brings the given data. A slow refresh data might bring about flickering and will be easily seen on bigger monitors. Most high-end LCD TVs have a refresh rate of 120 Hz (only current and former NTSC countries) This cause less distortion when movies shot at 24 frames per second are viewed because telecine is eliminated (3:2 pulldown). The refresh rate of 120 was selected as the least common multiple of 24 frames per second (cinema) and 30 frames per second (TV)

6. Matrix type
Active TFT or Passive

7. Viewing angle
Commonly known as viewing direction

8. Color support
Commonly known as color gamut

9. Brightness
The amount of light which is emitted by the display. Brightness is commonly known as luminance).

10. Contrast ratio
The ratio of the strength of the darkest dark to the brightest bright

11. Aspect ratio
The ratio of the height to the width (for instance, 4:3, 16:9 or 16:10).

12. Input ports (such as VGA, DisplayPort, DVI, HDMI and S-Video)

13.Gamma correction
