I hooked up my laptop to my tv with an HDMI cable instead of a vga cable i was using and I played a regular dvd and boy was the picture quality a lot better. what is the difference in using this set up vs buying a blue ray player in picture quality. Also would the picture quality increase if I use an HDMI cable with the blue ray instead of the rca type cables that comes with a blue ray player? Im asking because i am thinking of getting a PS3 for the blue ray player and using the HDMI cable that can be bought for it.
