I tried to find a list of iPad apps that will allow projecting via the VGA/composite/component cables and could not find one. I decided to use the power of the crowd to compile a list of the ones that work this way.
Here is the direct link to the spreadsheet with the compiled data.
Here is the link to the form to fill out once you have checked to see if the one you know about still needs to be added to the list! Thanks for contributing!
