4K is a theme at this year's Consumer Electronics Show, and the ultra-high-definition resolution is nearly within reach. Vizio and Polaroid will sell 50-inch 4K televisions for $999, and the entry-level price of a 4K desktop PC monitor has also dropped to just $699 this week.
30HZ IS HALF OF WHAT YOU'RE PROBABLY USED TO
Dell is the company selling a 4K monitor at that price: the Dell P2815Q. It's a 28-inch, 3840 x 2160 resolution screen with HDMI 1.4, multiple DisplayPorts, a bunch of USB ports, and the ability to charge a smartphone and display its content with MHL connectivity. Dell cut a few corners to get to that price, though: it's a standard TN panel, and it comes with one potential dealbreaker: when displaying 4K content, it only runs at the dismal refresh rate of 30Hz. Most 1080p monitors run at 60Hz or better, and recently some PC gamers have been adopting screens of 120Hz or above.
