Okay so I need some help with my ps3. Usually my dad plays it downstairs on our new tv, which hapens to be a 50 hd. So of course we would play it on hdmi. But when I take it back up stairs to my old piece of shit tv that dont have hdmi, it puts it on 480i. Now i know there is a way to change it to 720p with just regular cords but I dont know how...? Since my way old tv dont support hdmi how to i put it in 720p res? with regular cords
