Although the contrast ratio, CR, of a display is important, I generally ignore contrast ratio specs
The video display industry has been in a competitive "numbers war" battle regarding this spec for many years. Although there have been small incremental improvements over the past few years, the advertising specs would suggest there have been revolutionary
advances. Instead of a CR of let's say 1200:1, we see specs like 10,000:1, then 60,000:1, and even 3,000,000:1, but in truth what these numbers reflect is outright lying, fudging, exaggerating, and the invention of "new and improved" measurement criteria.
We also must consider they usually
don't state the test conditions, which can lead to drastically
different results: Are the claims of gray scale CR only, with no color present? ANSI standards? Full brightness on vs full off? Half screen black the other white? Center of checkerboard pattern measurement or edge? Was the measurement done in a typically lit living room or a pitch black bat cave? Static? Dynamic? With "Super Duper Ultra Wow Gamma Technology" turned on or off and what are the negative consequences of leaving it on? With crushed blacks, perhaps?
There are too many variables so I trust only independent test labs that state exactly what they mean, and when they publish data based on instrumentation readings. Anything less I simply ignore
Silicon Micro Display goes into more details, including that their spec accounts for 10% transparency to the exterior room/cockpit (so it is not a "bat cave" measurement, at all) here:http://www.siliconmicrodisplay.com/1...ontrast/1.html
