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 (2×2, 4×1, 3×1, 2 mirrored sets of 2×1, and 1×4) 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 4×4 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 deembedding 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.

   Note: When selecting a new source for while Video Wall mode, only audio de-embed port #1 routes to the video wall source to provide an audio zone synched with the video wall while enabling the other three audio zones to be used for other purposes.

5. Use the HDMI AV tab to route the desired Source to route to the HDMI output only.

6. Use the External Audio tab to independently route the desired audio source on the selected output / audio zone.

7. Press the Settings Button in the upper-right corner of the web UI to access most common installer setup options. These settings may also be applied using KDMS Pro or via IP/RS232 command strings:
   a. Enter the Naming Settings tab (7a) to assign a user-friendly Device Name, Input Name, and Output Name settings.
   b. Enter the Video Settings tab (7b) to apply Panel Flip and bezel adjustment settings. See the Panel Flip and Bezel Adjustment sections for more information.
   c. Enter the Network Settings tab (7c) to update the IP settings and web UI access password.

Video Wall Modes

KD-VW4x4ProK supports five video wall modes Important note about video wall source content:
It is necessary to obtain/create content designed for display in the aspect ratio of the video wall mode but is output by your HDMI source device in 16:9

• A common display’s aspect ratio is 16:9.
• Example: Working in the 1H x 4V mode, the width is 1 to 1 (1:1), but the height is 1 to 4 (1:4) because of the 4 vertical displays.
• Therefore, the correct source content should be 16:36
• Tip: 16 times 1 equals 16 for the width. 4 times 9 equals 36 for the height.

Panel Flip

Enables use of consumer monitors by mounting top row displays upside down and conjoining narrow frame sides.

• May be enabled via IR, KDMS Pro, TCP/IP and or RS-232 commands

• IR Remote button sequence is:
  o R3 button (section E)
  o Output # (section B)
  o VW Layout button 1 (enable) or 0 (disable)

• TCP/IP or RS-232 command is:
  o SPOxxDUy
  ▪ Where xx = Output # 01-4
  ▪ Where y = E (enable) or D (disable)

Bezel Control

While in video wall mode, the video signal to each display may be extended up to 99 pixels beyond the top, bottom, left, or right edge of the monitor’s screen. This setting is recommended for video entertainment applications (ie sports bar), but not for data viewing applications like spreadsheets because some content may be extended off screen.

This setting is applied using the following TCP/IP or RS-232 commands:

• Top border: SPOxxVCTyy
• Bottom border: SPOxxVCByy
• Left border: SPOxxVCLyy
• Right border: SPOxxVCRyy

Where xx = Output # (01-04)
Where yy = Number of pixels (00-99)

Example: 2×2 Video Wall

• Display 1 (top-left) needs no bezel control adjustments
• Display 2 (top-right) image gets extended to the left
• Display 3 (bottom-left) image gets extended up
• Display 4 (bottom-right) image gets extended to the left and up

Text Overlay

Text overlay available while in video wall mode.

• The assigned name of each display may be displayed in each window.
• This can be helpful if confused about the proper location of each display within the video wall.
• By default, the text shows as “Display 01” … “Display 04”.
• Use KDMS Pro or send commands via IP/RS-232 to set the name of each source, X/Y location of each text box, and to enable disable the text overlay setting
• 16 characters maximum with variable sizing (large / medium / small).
• The below image is an example of “large” text overlay applied.

• The X/Y grid for text box location varies based on output resolution setting of the KD-VW4x4ProK unit:
  o 4K: X = 0-3839, Y = 0-2059
  o 1080p: 0-1919, Y = 0-1079
  o 720p: X = 0-1279, Y=0-719

• The default X/Y value for the text box location is X = 100, Y = 100 (regardless of 4K, 1080p, or 720p output resolution)

TCP/IP and RS-232 Commands

TCP/IP Connection Protocol

• Default IP address = 192.168.1.239
• TCP/IP Port Number = 23
• Notes: Use Raw / Other service, not Telnet
  Maximum of one TCP/IP socket supported at a time.
  Simultaneous TCP/IP and web sockets are supported. Multiple web sockets are supported.

RS-232 Connection Protocol

• Baud Rate = 57,600 bits per second as default
• Data Bits = 8
• Stop Bits = 1
• Parity = None
• Flow Control = None
• Carriage Return = Required at end of each string

Notes:

• Commands are not case-sensitive
• Spaces are shown for clarity; commands should NOT have any spaces
• After a new command is received, a prompt should be sent back
