Gefen EXT-HD-VWC-144 overview

  • 1Description

The HD Video Wall Controller from Gefen takes a single HDMI source at up to 1080p resolution and splits it into four quadrants, thus providing a simple way for you to create a 2 x 2 video wall without investing in special video wall-capable displays. There are four HDMI outputs, with each output assigned to one of the four displays in the group. Because the resolution of the incoming signal is effectively quartered, the HD Video Wall Controller can also scale each of the outputs back up to 1080p so that the displays will receive a signal in their native resolution. HDCP is supported, meaning you can even pass copy-protected sources such as Blu-ray DVDs. Video walls are suitable for a host of applications that require an outsized display where using a projector isn't an option, including entertainment, digital signage, retail outlets, clubs, trade shows, control centers, building lobbies, and more.

Both local and remote control is possible with the HD Video Wall Controller. Front panel buttons and an on screen display allow settings to be changed locally at the device. Where line-of-sight communication is possible, there is an IR remote included. An IR extender port means you can even extend the IR signal over wire for non-line-of-sight scenarios by employing an IR extender kit sold separately. For remote and offsite management there is RS-232 and an Ethernet port. The device features a built-in Web server with Telnet and UDP support for control across and IP network or even the Internet.

    Gefen EXT-HD-VWC-144 reviews

    HD Video Wall Controller is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Super easy and working product - Installed over 3 months now I'm a tech geek with plenty of computer experience and volunteer director of Sound/Media tech at church. At the time I had never done a video wall and had hesitation to commit as a Learning Experience but budget was not sufficient for full professional project. I needed to build a video wall for our church fellowship hall / contemporary services (non-projection as stage lighting would interfere) and did not have budget for a 9 x high dollar daisy chained DVI monitor system. After lots of research I was considering a budget DVI controller from China with lots of DVI-HDMI adapters (several sources and names) when Gefen introduced this HDMI specific product at just the right time for me. While the spec asked of me was initially 9 (3x3) screen - it was also requested to be HD wide screen only larger. After discussion and budget review I developed a configuration with this Gefen controller and 4 x 70 Consumer class HD Smart TVs with narrow bezels. This yields approximately a 10'x 6' wall. Out of the box it worked flawlessly and simply. As I recall, my 2x2 setup at 1080p (1 screen output up-scaled across all 4 screens) was the default and the only adjustment needed was which HDMI cable was which screen position and the bezel adjustment/correction using the remote. We mounted the box on a shelf behind the wall with holes in the wall behind the mounts to pass power and HDMI cabling. A revision to this was to hang the Gefen Video Wall Controller vertically flat against the wall to relieve stress on the HDMI cables. This change resolved some intermittent issues. Also, in hindsight - if you are doing like we did (controller behind wall) I would suggest mounting the IR receiver extender (for the gefen box) somewhere on the front side of the wall so adjustments can be made easily. Have been using it for HD presentations and streaming. PROS: Worked out of the box, easy, simple, great quality, solid each weekend. CONS: Limited to 4 screens, bezel from tv's is center of screen so your application may have an issue with that. May not meet the needs of a small conference room where text may be a center-line of the display. Is fine for us using large text and video imagery. Overall, I completed entire project (wall controller, cables, PC to run presentation software, 70 TVs, Mounts, surge protectors, UPS, wiring, matrix switcher) for <$10k which was the budget. So far the biggest update is swapping out a cheap 4 x 2 HDMI matrix switch which died after 3 months (switching between 2 computers and This wall display as well as a pair of single-screen side-displays) for the Geffen toolbox matrix switch.
