Because the com- mercial space is a little slower to adopt 4K technology, the cost is still significantly different for many manufacturers." It may take some time for each manu- facturer to land on a price as they find their footing in the market, however. "As we see more 4 K content being introduced into commercial environ- ments, I believe we will see the same trend as in the consumer space," Heberlein says. Pratt goes on to explain that regard- less of price, it is "important to review your display requirements with your sign/display dealer and integrator to ensure you're getting the solution that's right for you." Compatibility—Of course, whenever there is a new technological advance- 4K resolution presents a much sharper image to the viewer, having four times as many pixels as 1080p. Screens viewed close-up retain their crispness. (Image courtesy of Planar) Media players need to be more powerful in order to efficiently process dense 4K data rates. The BrightSign 4K242 media player is a fan-less, solid-state, com- mercial grade 4K player that supports all of the new tech- nology standards of the 4K ecosystem. (Image courtesy of Brightsign) Optec Displays offers several 4K-capable screen solutions, including OPT-Panel (above), an ultra-HD led display module supporting 1080p, and 4k resolutions; and OPT-Slim, a super-light, ultra-thin, HD LED display.

(Take a new cell phone and an old charger, for example, they aren't always compatible.) It's no different with the arrival of 4K screen technology. "The digital media, the physical media, and the connection between devices and the display all need to be up to the task of showing 4K content," Pratt says. The connection is one area in which a solution now exists. "One major step display manufactur- ers have taken is to allow for 4K to be transmitted/received over one cable," says Heberlein. "Since consumer dis- plays drive the economies of scale, it became an undertaking for the group that implements HDMI standards. The current HDMI standard of HDMI 1.3 was only capable of transmitting a maximum resolution of 2560 × 1440, and since 4K resolution started at 3840 x 2160, some changes had to be made. In May 2009, the standard HDMI 1.4 was released, which allowed for resolution up to 4096 x 2160. Shortly after that time, both consumer and commercial 4K products started to be released."
