I have JB ipad 1st gen running version 4.3.3 and have Displayout installed. I want to hook it up to my Optoma ML 500 projector via HDMI, but I can't get it to work. I have the official Digital AV Adapter from Apple, connected to a HDMI cable (1.3) but I can't get it to mirror the ipad. I tried hooking up to my TV and it does not work either. Every time I plug in the adapter, the ipad displays a message that the accessory is not supported. Is it the adapter? I'm thinking it might not be compatible with the first gen ipad, only for the 2 gen. But then again, I think I saw some youtube videos of people "mirroring" using the Digital AV adapter with a 1 gen ipad, so I am confused. What am I doing wrong?
