California-based Tzero Technologies has demonstrated its new second generation ZeroWire in Tokyo. The new ZeroWire enables wireless HDMI transmission with Ultra Wideband (UWB) technology, which is able to transfer Full HD (1080p) resolution video at 60 frames per second. The product is at first targeted at Japanese market, but has passed the regulatory tests in Europe and the U.S. as well.
Tzero calls ZeroWire the first commercially viable wireless HDMI solution with an estimated material cost of less than $50. It support HDMI 1.3a and HDCP and therefore is “Hollywood Approved”, according to the press release. With 480 Mbit bandwidth the ZeroWire is able to transmit Full HD resolution video and 7.1 digital surround audio at ranges greater than 20 meters.
Due to its higher bandwidth the rival WirelessHD is a more viable option for future technologies. WirelessHD supports theoretical data rates of up to 20Gbps but is limited by the 10.2 Gbit bandwidth of the wired HDMI 1.3a.

According to Crunchgear, Apple has begun building HDCP (High-Bandwidth Digital Content Protection) into their new MacBooks in order to protect iTunes Store purchased media.
Although most content are not protected, there are some newer videos that are and will not play at all unless you have connected an HDCP compliant TV or monitor.
Users trying to connect to a TV via HDMI or DVI should be fine, but users with VGA or component/composite ports only may have issues.
To understand more about what exactly HDCP is, please read our glossary entry here: High-Bandwidth Digital Content Protection.

Dell has introduced a cheaper but more accurate replacement to their mid-grade 2007WFP LCD model dubbed the 2009W.
According to Dell, “the 2009W can reproduce 102% of the NTSC color range and boosts the contrast ratio from 800:1 to 2,000:1 through dynamic adjustments.” The display is also faster and sports a 5ms average pixel response time.
The display also improves on its predecessor’s input connections by allowing VGA input for analog video, a four-port USB hub, and HDCP encryption support for its DVI connector. The price is also cheaper than its predecessor, and retails for $289 USD.
