With displays, it is easy to get caught in the hype as technology buzzwords are meant to grab your attention rather than describe the actual screen quality. Super AMOLED, HD-IPS, Super LCD, Retina IPS, and whatnot, each claim to offer the best image quality around, but usually find it unnecessary to provide specific numbers, which would make technologies easier to compare.
On the rare occasions that display specs are actually quoted, the numbers are purposely chosen to be misleading and make the real-life performance seem much better than it really is. Which is where our first test comes in.
Perhaps the most important factor when it comes to screen quality is the contrast ratio. Contrast ratio is the measure of the dynamic range of the luminance of the display, essentially describing how much darker the deepest blacks are than the brightest whites. A display with a good contrast ratio is able to show richer, more vibrant still images and videos that come to life.
