0

Key Digital is now shipping its KD-VW4x4ProK 4K UHD Video Wall Processor and Seamless Matrix Switcher solution, which is engineered to deliver sophisticated video wall displays using consumer panels and monitors.

The solution features four HDMI inputs and four HDMI outputs, plus four mirrored Ultra High Definition over Twisted Pair (UHDoTP) outputs, providing signal extension to four included KD-EXMLVRx UHDoTP receivers.

“Creating an attention-grabbing video wall display has never been easier or more affordable,” said DeWayne Rains, Key Digital VP of sales. “All hardware needed to drive a four-monitor display is included, and the KD-VW4x4ProK is preconfigured so that just a few menu taps get the system up and running within minutes after monitor mounting and interconnection is complete. What’s more, the system is easy to operate from the free iOS KD-App and KDMS Windows software or by a built-in web graphical UI. The mirrored HDMI and CAT6 AV outputs are ideal for dual video walls showing identical content. The KD-VW4x4ProK is perfect for video wall and large-format viewing applications including bars and restaurants, sports and gaming caves, houses of worship, entertainment centres, museums and e-sports arenas.”

The KD-VW4x4ProK is designed for optimised use with consumer video displays and televisions. Its Panel Flip feature rotates the image 180° on the desired outputs, enabling the top row of monitors to be installed upside down, co-joining the often-narrower display frame sides and tops to minimise bezel visibility. Bezel compensation allows the image to be extended off-screen to create fluid screen transitions between co-joined monitors.

Five video wall layouts are supported: 2 x 2; 4 x 1; 3 x 1; two sets of 2 x 1; and 1 x 4. 4K/UHD content up to 3840 x 21640p 4:2:0 at 60fps is supported, with native down-conversion enabling integration with legacy 720p and 1080p displays.

“Alternatively, the KD-VW4x4ProK may be used as a 4 x 4 video matrix allowing viewing of four video sources on up to eight displays by way of the mirrored HDMI and UHDoTP outputs,” said Rains.

The Key Digital KD-VW4x4ProK is shipped with four KD-EXMLVRx UHDoTP receivers for signal and control extension

Audio routing is independent of video source selection with de-embedding of both two-channel analogue audio and 5.1 Dolby/DTS surround formats on optical digital connections on each KD-VW4x4ProK output.

Along with front-panel control, the KD-VW4x4ProK joins a suite of Key Digital IP-enabled products that are Web UI and iOS KD-App ready. Installers and users can switch inputs and control Key Digital systems from a Windows PC running the free Key Digital Management Software Pro (KDMS Pro) app or a portable iOS device with the free KD App. The mirrored UHDoTP outputs provide AV and bidirectional IR signal extension (up to 35m/115ft at 4K) and Power over CAT (PoC) from a single CAT6 cable run – IR remote control signals travel along with the AV signals to the KD-EXMLVRx units for display control, or for system source control back from the monitor installation location. System control is also available through RS-232 and supported TCP/IP control systems via open API.

Content standards supported by the KD-VW4x4ProK include the HDCP 2.2 anti-piracy protocol; the HDR10 standard for high-dynamic-range video; and EDID management for display recognition. It also offers deep colour support up to UHD/4K 30Hz 4:4:4/12-bit or 60Hz 4:4:4/8-bit. A full buffer system manages HDCP authentication, EDID control handshakes and TMDS re-clocking/signal re-generation for serial data optimisation.

The Key Digital KD-VW4x4ProK is available for immediate shipping at a MSRP of US$2,950.
