Would agree J+P for this, especially for tiling. I looked to SAVI and AVProEdge for solutions as well. At the end of the day, the panels from Samsung and LG were too salty for our proposal, especially when combined with the back end hardware. The panels can essentially act as one display for picture and control so no additional “rooms” would need to be used for C4. Also, Blackwire Designs has a stellar driver for the J+P tiler.
