Google Nexus 7: The Display

We're on our way to wrapping up our tests on Google's very first touchscreen tablet, the Nexus 7, made in partnership with Asus. Before publishing the full review, we thought we'd give you a taste of what to expect. So here are the initial results from our screen tests...

Google Nexus 7 is the first Android tablet to feature Jelly Bean, the 4.1 version of Google's operating system. It boasts an Nvidia Tegra 3 quad-core CPU, 1 GB of RAM and a choice of 8 or 16 GB of storage for £159 or £199, respectively.

The 7-inch IPS capacitive touchscreen has 1280 x 800 resolution, which gives it the highest pixel density on any small-sized tablet. Before we start our little mini-review here, let's just point out that while games, web pages and photos can be flipped from portrait to landscape mode, the rest of the OS interface runs only in portrait.

Our sensor showed us some excellent results for the display rendering. It's bright with a maximum brightness of 321 cd/m²—although that's not the highest on the market—and has a very good average contrast of 920:1. That puts the Nexus 7 in the upper average in terms of contrast, just about the same as the last two iPads.

The Best 7" Display Out There?

Subjectively eyeing the display, the colours look fairly well-balanced, with no major overkill in any tone. And that's what our sensor told us, too, with an average Delta E of 6.1. Delta E measures the deviations between the intended colours and the colours displayed onscreen, and ideally should be below 3. The Nexus 7's 6.1 is pretty far from that and the new iPad's 2.2, but other than the slightly untamed blues and greens, the greys, reds, yellows and blacks are all quite faithful to the true tones.

In fact, the 5570 K average colour temperature stays put throughout the spectrum and ends up holding these deviations back.

The ghosting time is 23 ms, which places the Nexus 7 in the lower average in this category for IPS displays. As for the screen's legibility, with 1280 x 800 pixels we had been expecting a slight advantage over ordinary 7-inch tablets, which max out at 1024 x 600 resolution. And that's exactly what we got. All our testing charts appeared perfectly clear onscreen. In the very worst case, you may have to zoom in a bit to read certain text. Speaking of which, the zoom function is super-smooth and targets the zone you want to zoom in on just as you intended it to.

The Nexus 7's screen is nothing short of the best 7-inch tablet display we have ever reviewed!
