I bought a mini display port to hdmi converter to connect my 2009 macbook pro 15inch to my vizio 37inch TV. i think the model number for the vizio tv is 370VA or something like that. but the problem is when i connect the cables the macbook will detect that its connected but my TV screen is blue and said no signal. I don't know why macbooks screen isn't on the tv. I tried changing the resolution. rebooting. and everything... HELP
