Okay so I have a VGA computer screen. It's what I used to play my xbox via a 360 to vga cord. I bought cheap one for my wii also. It works but every couple of minutes the screen goes black and flickers off and back on again. I did a little research and I think it might be because of the cheap cord. So I need to know what I need to buy in order for this not to happen. I'm guessing another cord but I'm unsure as too what brand I should get. Thanks!
