I'm currently working on a project for my local church where they are installing 3 Vizio model M550VSE. We are wanting to use a desktop/laptop to run a power point sermon and to run DVD player thru the computer. The plan is to use 3 Stellar Labs model # 33-12570 active balun's one to each TV, with a router. Is this possible? What type of router would I need to get? Would I need additional software?
