Just brought COD4 for my PC but when i go to play it it says video card doesnt support separate alpha blend (what ever that means) ive updated the drivers on my graphics card so i presume that the card is to old so it wont work. Ive installed it on my laptop but i want to play it on a bigger screen but theres no video out on the laptop is there a connection lead avaliable that i can use from one of my USB ports to the connection on the T.V cheers
