I'm going to shortchange you here. It's an old issue with the video presence pin. Samsung has decided to not implement that anymore as not all cables wire that pin. You can see what's up in this video. I will not repeat that this applies to other makes.

I am trying to connect my Toshiba Satellite L350-277 laptop with my LG tv via vga cable. When the cable is plugged in the RGB port does not show as being in use on the TV's Input list and therefore I cannot select it. Have tried all sorts of things and the cable is definitely working fine and the problem is not a resolution one as I have hooked up to 2 other smaller TV's with no problem...just plugged the cable into the laptop's VGA and TV's RGB and all worked no problem. Please help!!!
