What is 4K Ultra HD?

4K Ultra High Definition television (UHDTV) is a new standard that dramatically improves upon the picture quality and detail of 1080p Full HD. In October 2012, the Consumer Electronics Association defined and approved the Ultra High Definition standard, which calls for a minimum resolution of 3840x2160. The high resolution of Ultra HD increases picture quality in large displays, enabling closer viewing without noticing pixels. Ultra HD can also improve small displays, providing increased definition in the same sized screen. Ultra HD is the next logical step in the progression of display standards, and will be supported for years to come.

How One Business Benefits
from Ultra HD

Garden Emporium, a modest-sized indoor / outdoor gardening store, wanted an effective way to improve the look of their outdoor video kiosks, which are located on isle end caps. Customers often stood close to the 60” vertical 1080p displays, and complained about blurry text. To solve the problem, Garden Emporium chose to replace them with 60" Ultra HD LED displays. The PC that powered the kiosks had a video card that supported 4K resolution, thus out of the box the text looked crisp and sharper. Their splitter was upgraded to the Gefen ToolBox 1:8 Splitter for HDMI 4K2K which was required to distribute a 4K signal to the panels.

Now, many businesses like Garden Emporium are upgrading to Ultra HD and, using Gefen’s wide portfolio of 4K UHD products, are able to take advantage of high resolution displays.
