Hi, I have an IPAD 1.
I'm a teacher and want to push the screen to my NEC VT470 LCD Projector.
I have bought BOTH cables from Apple. 1.) VGA to 15 pin connector 2. RCA plug to red,white,yellow RCA plug.
Both cables give me a black screen and "no input" flag. My screen is usually blue, so I know SOMETHING is getting there.
