I just bought 42 inch e series vizio tv and when I try too hook up my macbook pro, it will not display. I have tried both an apple vga adapter and a monoprice hdmi adapter with no luck. The computer knows the display is there but nothing will work. I can only get it to display when I move the resolution all the way down to 640x480 and mirror the displays. The tv says "invalid format". oh btw, I use this macbook pro with my 1080p acer monitor all the time and with other tvs in my house.
