About KD-MLV4X4PRO

Key Digital’s KD-MLV4x4Pro is a 4 HDMI input with 4 HDMI + 4 UHDoTP mirrored output matrix, multi-view

tiling video processor, and independent audio routing.

KD-MLV4x4Pro is perfect for applications like Sports & Gaming Caves, Bar & Restaurant, Corporate AV, House

of Worship, Entertainment Centers, Museums, and E-Sports. Or, simply use KD-MLV4x4Pro to deliver wow-

factor to your distributed video systems.

The multi-view tiling processor enables users to view up to 4 video sources at the same time on a display in

different default and custom layout presets. Custom and multi-view layouts include the option to layer content,

applying desired bezel frame width and color.

4K / UHD content up to 3840 x 21640p 4:2:0 at 60fps is supported and when in full-screen mode switching from

source to source is completely seamless. Integrate with legacy displays or projectors by applying 4K to 1080p

or 720p down-conversion as needed. Each output has mirrored HDMI and UHDoTP connections, for a total of 8

possible connected displays. Four (4) Receiver units are included, and they get their power from the main unit

for ease of installation.

KD-MLV4x4Pro supports 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 multi-view mode.

For ease of installation and viewing, KD-MLV4x4Pro features 9 built-in test patterns and optional on-screen

display text for each source. KD-MLV4x4Pro supports HDCP 2.2, provides EDID handshaking to the connected

source from a library of 8 AV profiles or a copy of any connected display’s EDID file. IR from a control system

may be input at KD-MLV4x4Pro and extended to control the displays connected to the KD-EXMLVRx units.
