My daughter has an Xbox 360 that is hooked up to the tv in the playroom she shares with her brother. Her brother just received an Xbox 360 for his birthday. If I purchase televisions with hdmi slots, can I hook their games up to the tv sets in their rooms without the tv sets being connected to our satellite? Both of my kid love playing Minecraft and we have wifi throughout our house. Will this set up work for them to be able to play Minecraft on their own tv sets in their rooms?
