LCD Screen Jargon explained
|Screen size||Usually measured in inches across the diagonal||Bigger is better: A 14-inch screen is twice as big as a ten-inch screen, which is twice as big as a seven-inch screen.|
|Screen resolution||Strictly speaking, the number of pixels per inch, but usually expressed as the number of pixels in the whole screen||The bigger the numbers, the better the picture quality is likely to be.|
|Screen brightness||The brightness of the screen, usually expressed in units called “nits.” 1 Nit = 1 candela per square meter||Ways of measuring brightness vary, so direct comparisons are difficult, but generally big numbers are best.|
|Contrast ratio||The ratio between the amount of light coming out of a white area on the screen and the amount of light coming from a black area||Ways of measuring contrast vary, so direct comparisons are difficult. But large ratios are generally best.|
|Viewing angle||The angle over which the picture is visible.||
Different manufacturers have different definitions of what is “visible,” and some of them may not agree with yours. Best to check for yourself at a boat show.
