I don't know what you mean by otg? But there are cables made for all apple iphone and ipad devices to support a/v to a tv. Hdmi or a/v cable.

Would and Iphone vga adapter to hdmi work for surround sound? I have a connector for my iphone that connects from the charger port to hdmi, would this work to play audio to my surround sound speakers or would I have to get an Aux cord adapter?
Why is Apple so keen to push USB-C with their Macbooks but they don't include USB-C on the iPhone? It seems like the Macbook department at Apple thinks USB Type C is the best thing since sliced bread but the iPhone department thinks USB Type C is work of the devil.
What devices have HDMI output other than DVD/Blu-ray players, game consoles, and some computers? I have a monitor, I wonder what kind of devices can project their images onto the screen other than video players and game consoles. Any way to project the image of my tablet/phone onto the screen?
My iPhone 3G doesn't support my Apple Orriginal HDMI Cable? I just bought an Accessory from apple and it seems its not supported. I used "Supported4" from thebigboss (cydia tweak) and its not working. I thought that it will fix the bug. Is there any tweak that i can use to fix this bug/problem?
