What specifications are important on an LCD monitor?

May 22, 2009



You’ve been tasked with purchasing new LCD monitors for your organization’s call center team. What specification is not applicable for an LCD monitor?

A) Aspect ratio

B) Refresh rate

C) Native resolution

D) Viewing angle


The answer: B) Refresh rate

Unlike CRT displays, LCD monitors don’t require the screen to be constantly refreshed to maintain an image. The speed of the LCD pixel changes are usually referenced as response time in milliseconds.

The incorrect answers:

A) Aspect ratio
The aspect ratio is the difference between the height and width of the display. Traditional displays have a “square” ratio of 4:3 and newer LCD displays may have a 16:9 widescreen ratio.

C) Native resolution
The native resolution of an LCD monitor is the number of physical pixels available on the display. Unlike CRT displays, LCD presentations can’t modify their screen format based on different resolutions. The LCD display will always look best when displayed at its native resolution.

D) Viewing angle
Liquid crystals are best viewed from directly in front of the display. As you move away from the front viewing display, the visible portion of the LCD monitor will begin to obscure. The viewing angle is important if there are many people viewing the LCD display at a time.
