The most exciting feature about the Nexus 7 is of course its extremely sharp 1920 x 1200 pixel 7-inch display. It is actually sharp enough to qualify as ‘Retina’ - its pixel density goes over 320ppi after all.
The display should be an absolute joy and to better enjoy the experience Google has introduced a few new high-resolution wallpapers that are awesome. They add to the already great pack of Android wallpapers. You can take a look at the new and old ones, and download the ones you like right below.
