We finished building out this 20-touch video wall for Connect2014 today using a custom IR Touch frame. The displays are 3x3 NEC 462UN’s (46” seamless displays).
Mounting the frame to the seamless screens was challenging. We ended up building out some aluminum “L” struts as an external mounting bezel. This worked remarkably well as we were able to adjust the overlay along the surface of the screens at several places.
We also deployed this setup at NRF a couple of weeks ago (the second booth photo) however, we didn’t have the framing ready, so the touch system was only partially active.
