1×4 HDMI 4K UHD Video Wall Processor with Bezel Correction
Create Video Walls from 2x2, 2x3 & 3x3 screens up to 9-Displays
The KanexPro VW-SP-1X44K is a 4K based video processor which allows one HDMI input to be freely arranged on to four 4K displays. It offers bezel correction support with a simple and easy to use control application. The device supports video output timings up to WUXGA@60 and 1080p@60Hz, audio format up to 7.1CH LPCM at 192kHz sampling rate based on input source EDID. Easy to Control from Anywhere The video processor can be controlled from anywhere using a tablet or any other 3rd party control system using RS-232 and Telnet. Applications: Ideal for digital signage markets, large scale presentations, hyper market displays and command and control applications where high resolution video wall is needed.

Questions
- What input resolutions does the VW-SP1X44K accept?
- The HDMI IN port accepts PC resolutions from VGA up to WUXGA, HDTV formats from 480i up to 1080p, and 4K2K at 24, 25, or 30Hz.
- What output resolutions does the VW-SP1X44K deliver to each display?
- Per the unit's Output Resolution reference table and its Introduction, output video timings top out at WUXGA@60 and 1080p@60Hz -- the Introduction explicitly states supported output timings are 'up to WUXGA@60 and 1080p@60Hz,' and no entry in the output resolution table exceeds 2048x1152 (RB).
- How do I configure a video wall layout and bezel correction by command?
- Set the wall format with SMN N1 N2 (N1=row, N2=column, each 1-15), then apply SBH N1 and SBV N1 (each 0-255) for horizontal and vertical bezel correction, and SBEZ N1 to enable or disable bezel correction (0=Off, 1=On).
- How can multiple VW-SP1X44K units be combined into a larger video wall?
- The unit can be cascaded to create video walls of up to 3x3 (9 displays), using the Cascade Output shown in the connection diagram to daisy-chain a second unit -- for example, two units combine to drive a 2x3 (6-screen) layout.
- How is the VW-SP1X44K powered, and what does it weigh?
- It is powered by a 12V/3A DC locking power supply (US/EU standards, CE/FCC/UL certified) rated at 12.98W consumption, and weighs 6.51 lbs (2956g) in a metal black 1U (19 in) rack-mountable chassis.
- What is included in the box?
- The package includes one VW-SP1X44K, one 12V/3A DC power adaptor, and one operation manual.
- Video appears with incorrect colors when feeding a resolution above 4K2K. What should I check?
- The device only supports RGB color space for input signals above 4K2K -- YUV is not supported at those resolutions. Set the source to output RGB rather than YCbCr/YUV.
- RS-232 commands are not controlling a multi-unit or cascaded video wall setup. What should I check?
- RS-232 control is limited to a single Video Wall unit and is not intended for use with cascade or bypass output connections. Use Telnet via the CONTROL RJ45 port with the VW-SP1X44K AP application instead for multi-unit control.
- Why choose the VW-SP1X44K for a growing video wall deployment?
- A single 1x4 unit can be cascaded with additional units to build video walls up to 3x3 (9 displays), letting integrators scale a deployment without swapping out the original processor hardware.
- Can the VW-SP1X44K be used for something other than a video wall?
- Yes -- it can also be used as a straightforward 1x4 distribution amplifier (splitter) when bezel-corrected video wall output is not needed.
