Enter the IP address of your FOURKAY Modular Matrix on the start page, hit the 'Connect' button and you'll be taken to a screen to manage the routing of your sources to your TVs. You also have the option to give your input sources and your TVs user friendly names. If your Sky Q or Sky HD boxes are on the same IP network as the matrix then you will be able to manage these (navigate and change channels etc) from within this app as well.
