Key Digital ships 4K video wall processor and matrix switcher
The KD-VW4x4ProK is an all-in-one 4K UHD four input four output video wall processor and seamless matrix switcher by Key Digital.
It has been engineered to cost-effectively deliver sophisticated video wall displays using consumer panels and monitors, said Key Digital. The KD-VW4x4ProK 4K UHD video wall processor and seamless matrix switcher has four HDMI inputs and four HDMI outputs with four mirrored UHDoTP (ultra high definition over twisted pair) outputs providing signal extension to four KD-EXMLVRx UHDoTP receivers, which are included.
“Creating an attention-grabbing video wall display has never been easier or more affordable,” said DeWayne Rains, Key Digital’s vice president of sales. “All hardware needed to drive a four-monitor display is included, and the KD-VW4x4ProK is pre-configured so that just a few menu taps get the system up and running within minutes after monitor mounting and interconnection is complete”.
It is also designed to be easy to operate via the free iOS KD-App and KDMS Windows software or by a built-in web graphical user interface. The mirrored HDMI and CAT6 AV outputs are for dual video walls showing identical content. The KD-VW4x4ProK can be used for video wall and large format viewing applications including bars and restaurants, sports and gaming areas, houses of worship, entertainment centres, museums and e-sports arenas.
The KD-VW4x4ProK’s functionality optimises its use with consumer video displays and televisions. Its panel flip feature rotates the image 180 degrees 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 supported video wall layouts (2 x 2, 4 x 1, 3 x 1, two sets of 2 x 1 and 1 x 4) make the KD-VW4x4ProK practical for building budget-friendly video walls for any application, said Key Digital. 4K / UHD content up to 3840 x 21640p 4:2:0 at 60 frames per second is supported, with native down-conversion enabling integration with legacy 720p and 1080p displays.
It can also be used as a 4×4 video matrix allowing viewing of four video sources on up to eight displays by way of the mirrored HDMI and UHDoTP outputs. Source selection in video wall or matrix modes is seamless.
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.
The mirrored UHDoTP outputs provide AV and bi-directional IR signal extension (up to 35m / 115ft at 4K) and PoC (Power over CAT) 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.
The KD-VW4x4ProK supports 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.
