About KD-VW4x4ProK
Key Digital’s KD-VW4x4ProK is a 4 HDMI input with 4 HDMI + 4 UHDoTP mirrored output video wall processor
and seamless matrix switcher with independent audio routing.
KD-VW4x4ProK is perfect for video wall and large format viewing applications like Bar & Restaurant, Sports &
Gaming Caves, Digital Signage, House of Worship, Entertainment Centers, Museums, E-Sports, and more.
KD-VW4x4ProK has been specially engineered to cost-effectively create video walls with consumer panels and
monitors. The Panel Flip feature rotates the image 180 degrees on the desired outputs, enabling the top row of
monitors to be installed upside down, conjoining the narrow frame sides of the displays. Bezel Compensation
allows the image to be extended off the screen to create fluid screen transition and five supported video wall
layouts (2x2, 4x1, 3x1, 2 mirrored sets of 2x1, and 1x4) make KD-VW4x4ProK the ideal choice to build video
walls in any application and price point.
Mirrored HDMI and CAT6 AV outputs enable up to eight connected displays via the four included Rx units- Ideal
for dual video walls showing the same thing at the same time.
Alternatively, KD-VW4x4ProK may be used as a 4x4 video matrix so users may view their four connected video
sources on their four/eight connected displays. Source selection in video wall or matrix modes is completely
seamless and 4K down-conversion features enable integration with legacy 720p and 1080p displays for further
savings by the end-user.
4K / UHD content up to 3840 x 2160p 4:2:0 at 60fps is supported, as well as independent audio routing with de-
embedding on analog balanced/un-balanced and digital optical connections and surround formats up to 5.1
Dolby® / DTS™. Audio from any source may be selected while in video wall mode.
KD-VW4x4ProK joins a suite of Key Digital IP enabled products that are Web UI and iOS app ready. The
engineers at Key Digital have created an easy way for installers and users to switch inputs and control Key
Digital systems as if you were standing in front of the unit - all from the PC or portable device. IR from a control
system may be input at KD-MLV4x4Pro and extended to control the displays connected to the KD-EXMLVRx
units.
