depends how far your pc will be to the tv and what equipment your pc is equipped with. My pc has a graphics card with an hdmi slot. My tv has an hdmi slot and with an hdmi cable, from about £10 up, the two can be connected together. As for running from a distance you could feed a tv next to the pc as described above and get a video sender to plug into the 2 tvs and pass stuff wirelessly. £35 upwards from the likes of maplins.
