Wireless technologies have come a long way in the past couple of years and continue to improve. Two of the best in my opinion are the Mersive solution and the Kramer VIA solution. By choosing wireless for your connections for auxiliary or guest laptops, you don’t have to continue to change out cables every few years. The worst case is that the wireless technology changes (hopefully improves) and you simply have to swap out the receiver. This is the solution we are choosing for many of our rooms.
