Hi, I have a goldcoast broadband cable for my internet and television. I have an HDMI cable that connects from my wall to my TV and then have a wireless modem. I have another TV that I would like to add to the kitchen but do not want to purchase another broadband box. Instead I would like to split the broadband with another HDMI cable. I know they will play the same channels at the same time and that's okay. What is the splitter that I need to use for this? Thanks!
