to run my computer to my tv and my computer only has a hdmi plug in & I don't have any money to be able to buy a converter or any kind of cable that would make it simple. I dont have cable, someone gave me this cable box to see if i could run the hdmi from my computer to it an it pull up on tv.. I just really need to know if thats even possible because Im desperate to figure this out an tired of wasting time & defiantly having to watch tv off this really small computer screen HELP
