Call it 4K. Call it UltraHD. Either way, massive pixel counts are the next big thing. This year’s festival of rampant consumerism at CES in Las Vegas is a case in point. Inevitably, a ton of 4K HDTVs filled the field of view in every direction, but the show also included several 4K and UHD laptops. Meanwhile, phones with full 1080p grids are becoming commonplace. Likewise, tablets with panels over 1080p, including Google’s 2560x1600-pixel Nexus 10, are now almost routine.
