okay so i just bought a new computer, and is had an nvidia graphics card. it's the first card i've had that was worth a damn so i tried hooking up the s-video to my tv and monitor using dual veiw or whatever, i liked the tv picture so much i decided to do single display on the tv only. then i started to have trouble so i went to switch it back to my monitor and for some reason instead of tv and monitor being my only choices there was a third choice "analog" so i clicked it to see what would happen and the screen shut off. in a panic i began cursing and hitting buttons... so anyway, now i have no picture on my computer and no way to re-route the v-out to any of the 2 working choices... i'm not very computer savvy. what do i do?!!?! i use windows xp. pls help!!!
