I have finally decided to get a HDTV or should I say my normal TV decided for me when it finally died after a long 15 year life, but there is one question I need to ask is there any extra cables or adapters that I will need to purchase to be able to use my xbox and PS3 on my new TV, I don't think there will but I'm just making sure.
you dont need any new cables but you can get hdmi cables which increase picture quality , but the really old xbox's dont have a hdmi port :\ but your ps3 should.
I agree with Ltpenguin. You should get an HDMI cord if you have a port for one. The picture quality is so much better. Some places like Best Buy might give you one for free if you buy the TV from them. They put up a fight at first but keep pounding them and they will relent.
