With manufacturing improving, Retailers and manufacturers including China manufacturer throw around a lot of numbers and terms to describe their products. So, how does one know what all these mean? The following looks to cover the basics so one can make an informed decision when buying an 9 inch LCD monitor.
Aspect Ratio
The aspect ratio refers to the number of horizontal pixels to vertical pixels in a display. Traditional displays used a 4:3 aspect ratio. Most new widescreen monitors use either a 16:10 or 16:9 aspect ratio. The 16:9 is the ratio typically used for HDTVs. Now a new breed of ultra wide monitors is coming to market. These have a near 2:1 width to high measurements.
Native Resolutions
All 9 inch LCD monitor screens can actually display only a single given resolution referred to as the native resolution. This is the physical number of horizontal and vertical pixels that make up the LCD matrix of the display. Setting a computer display to a resolution lower than this resolution will either cause extrapolation. This extrapolation attempts to blend multiple pixels together to produce a similar image to what you would see if the monitor were to display it at the given resolution but it can result in fuzzy images.
Contrast Ratio
Contrast ratios are a big marketing tool by the manufacturers and one that is not easy for consumers to grasp. Essentially, this is the measurement of the difference in brightness from the darkest to brightest portion on the screen. The problem is that this measurement will vary throughout the screen. This is due to the slight variations in the lighting behind the panel. Manufacturers will use the highest contrast ratio they can find on a screen, so it is somewhat deceptive. Basically a higher contrast ratio will mean that the screen will tend to have deeper blacks and brighter whites.
Color Gamut
Each LCD panel will vary slightly in how well they can reproduce color. When an LCD is being used for tasks that require a high level of color accuracy, it is important to find out what the panel's color gamut is. This is a description that lets you know how wide a range of color the screen can display. The larger the percentage of NTSC, the greater level of color a monitor can display. It is somewhat complex and best described in my article on color gamut.
