The 7-inch LCD display rocks a resolution of 1920 x 1200 and an intense pixel density 323 ppi. Though seven inches isn't a ton of visual real estate (this is a "mini" tablet, after all), it makes movies look magnificent and keeps text nice and crisp. It's bright, colorful and among the best tablet displays on the market.
When we reviewed the Paperwhite, we bumped up against the limitations of a black and white display when trying to read comics or books with photographs. That's in no way an issue here, the Kindle Fire HDX makes all your Amazon purchases look incredible. Of course, it's more draining on the eyes than an e-ink display, but certainly the more versatile device of the two.
Amazon currently makes the best ereader on the market, the near perfectKindle Paperwhite. It's mopped up all competition from Nook and the like, but the 7-inch tablet is a different sort of game.
The tablet world moves fast and Amazon is iterating just as quickly as the competition. So far its matched the yearly refresh rate of Google and Apple, debuting the Kindle Fire HDX only twelve months after the first Kindle Fire HD. My those tablets grow up fast.
Its backlight is a bit less powerful than that of the Nexus 7, but in day to day use that won't matter much, unless you're prone to browsing in a completely dark room. We detected only one little flaw, a bit of black shadow along the display's edge. It's only visible when reading something with a completely white background like an ebook. Still, it's a rather disappointing bit of quality control, like the dark spots that appeared on the first Paperwhite, but were gone by the second iteration.
Other than those dark spots, it stands among the best tablet displays on the market. Holding it next to a Nexus 7 or any Retina iPad, you'd be hard pressed to notice a difference, so it doesn't best the competition, but watching a film on an HDX is just as nice as on any high-density 7-inch tablet.
A bit of thickness has been shaved off its frame, giving it a depth of .35 inches, whereas the old HD was .4 inches.
It's built from the same soft touch plastic material as the Kindle Paperwhite. It's pleasant to hold and grippy without feeling sticky.
It's still a bit dull looking, especially from the front. The rear is actually more attractive, with subtly shiny black plastic and tapered, sloping edges.
When closed up, it lays flat across the display and the rear, shielding it from scuffs and scratches while adding little to the devices bulk. It converts to a stand by folding the flap back and pinching it together. It holds it at a perfect horizontal angle for movie watching, and keeps it upright in portrait mode as well, though with a slight lean.
The cover sticks to the rear with a magnet of impressive strength. You can hold it by the flap and give it a shake without causing a tumble. If you're buying an HDX, you really ought to consider some sort of cover, if not this one. No one likes a scratched tablet.
With the Kindle Fire HDX, it's also built an excellent Android tablet, from a hardware perspective, at least. But while it's lightning fast and a great way to enjoy books, magazines, comics, music and movies, it comes up short in the places where the best tablets truly impress: third-party apps and a whiz bang customizable interface.
Amazon has all the media you crave, plus tube socks and cat food at rock bottom prices. It's built a great tablet, an Android one despite what its Fire UI wants you to think. But while it excels at getting out of the way so you can read, watch and buy, buy, buy, is it lagging behind the feature curve set by Google and Apple? Let's break it down.
The 7-inch Kindle Fire HDX is no supermodel, but it is better looking than its predecessor, the brickish Kindle Fire HD.
We don't often talk about accessories in a device review, but the origami case sold by Amazon deserves a shout out. It's quite expensive at £45 for plastic and £50 for leather, but it's a really elegant combination of protective cover and stand.
Amazon opted to place the power button and the volume rocker on rear of the HDX. They're clicky and easy to press, but despite their sunken design, it's often hard to locate them. We frequently mixed up where they were, especially when holding the HDX in portrait orientation.
The requisite 3.5 mm headphone jack is found on the right side, and a microUSB is on the left. Both do their jobs while keeping cords from trailing over the display. There's also a front facing camera above the screen, but no camera on the back.
Overall, it's a functional, but less than eye catching design. It looks like something a power tool company would design, a construction worker's tablet, until you light up that screen. This is one of the places where Amazon's hardware stands toe to toe with the competition.
It weighs just 10.7 ounces, so it's light enough to carry day to day without adding much weight to your bag. Its overall dimensions are 7.3 x 5 x .35 inches, making it easy to hold in one hand, but too large for a pocket.
The HDX has fine speakers as well. They're mounted on the back of the tablet, near the top, so it's easy to hold the tablet without covering them up.
We've heard louder sound on other tablets, but even at maximum volume, the HDX is free from the distortion that sometimes popped up on last year's model. It doesn't scream, but it's good enough to watch videos outside in a park without switching on the subtitles.
