Full HD resolution have Nexus 7 and iPad mini as well, but the color values ??and viewing angle stability of the Amazon Kindle Fire 7 HDX not reach. enlarge class=”source”> Image: Amazon For about a year Amazon sold in Germany and tablets under its own name. With the Kindle Fire HDX HDX 7 and 8, the new models are now available in this country and has already arrived in the c’t lab for testing. Your direct competitors hot Apple iPad mini with so-called Retina display and Google’s Nexus 7 with full HD display – they also had to undergo the tests in the laboratory. We have taken the screens of the four units more closely and compared. The result: In the tablet compact the HDX outperforms all three rival 7

.

The measured values ??of the LCD recall the properties of an AMOLED display: The color space exceeds the requirements for sRGB, especially green are the HDX 7 again better than the standard prescribes. For the far higher claims of AdobeRGB but it is not enough. The possible viewing angle is so great that it almost does not matter from which angle you look at the display.

Google and Amazon seem the same screen manufacturer to shop, because the display of the Kindle Fire HDX 8 and Nexus 7 have almost the same values ??and show virtually the same viewing angle. The sRGB color space, they cover both the green and shoot even a little bit beyond. Only in contrast with the Amazon tablet has the best nose 1311:1 far forward – the Nexus [7] achieves only average 892:1

slightly lags behind the color space, the iPad mini, which weakens not display sRGB entirely covers and especially red and green. Viewing angle and contrast of 979:1, however, are roughly on par with the Nexus 7
