The reason for the change is that we realized AMOLEDs were universally better than LCDs in this test. You can find the full explanation of the test below but it's no longer carried out on new devices. Update Mar 4, 2020: This review test has been discontinued. While a brighter display would normally have an advantage, it will usually be unable to compensate for insufficiently deep blacks. When we measure, we take two readings off each device - first with the display brightness set to 50% and then with the brightness setting pushed all the way up.Ĭontrast ratio is very heavily influenced by the black levels of a display. As AMOLED units have the ability to completely switch off individual pixels, their black level readings are 0, which gives them an infinite contrast ratio under the testing conditions. So, a display which has 100 cd/m2 of whites and 1 cd/m2 of blacks will have a contrast ratio of about 100:1.Īn important note about AMOLEDs is due here. The contrast ratio itself is determined by measuring the cd/m2 of a pure white screen, and dividing it by the cd/m2 of a pure black screen (note that on an LCD a pure black screen is not the same as a screen which is turned off, because even black pixels emit some light). For displays, light is measured per square meter of surface area ( cd/m2), which is sometimes also referred to as Nits (nt). One candela-which stands for candle in Latin-is the equivalent of the light intensity of one candle as perceived by the human eye. The brightness of a given object is measured in candela (cd), which is the scientific unit for luminance. A display with a good contrast ratio is able to show richer, more vibrant still images and videos that come to life. 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. Perhaps the most important factor when it comes to screen quality is the contrast ratio. 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. 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. I'm sure third parties will come up with bluetooth answers, but it's not like Apple to leave easy accessory money like that on the table.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. The Mini is an ideal light-duty work "laptop" for a weekend away or a train commute, but even just dealing with email requires a keyboard to do it efficiently. When hasn't this been true of LCD tablet displays from every company? And this is a con of the Mini?īut the con that surprised me most was the obvious one that was missed: the lack of a smart connector and accessory keyboard solution. Personally, I prefer Face ID, but Touch ID fans aren't a small minority, there's an ongoing wish for Touch ID under the display, so I'd call this one a toss-up at best. Paying more to get more is pretty much how all pricing works. Only the buyer can determine if all this is worth an extra $170, but the higher price tag can hardly be considered a con against the Mini. It costs more because you get more: better display, much faster processor, way better camera system, WiFi 6 and Bluetooth 5 future-proofing, 5G cellular, etc. Well, in that case, this would be a con of every iPad that's not the entry level unit, which makes no sense. Who exactly is buying this as their multitasking machine? (Small trunk! I can't even do a Costco run!) I'm mean, c'mon-it's an 8-inch display. Tedious multitasking? Sure, and I guess it's a con of a Porsche 911 Turbo that it's tedious for hauling cargo. The listed "cons" are really kind of odd.
