Topic: Lego Batman 3 - how to switch controller type on Wii U?

I've recently bought a Wii U for my children, but using it in games sometimes baffles me a bit. I have been through the regular options in Lego Batman 3 and cannot seem to find anywhere to change the type of controller from the gamepad to the pro/remote controllers. Could anyone lend me a hint here?

Generally what I've done in the past is shut off the gamepad screen (home button, select controller settings and shut the gamepad display off), and then I've just turned on the other controller.

The only way I have found to get the Gamepad actually turned off is turn it on via the gamepad then turn the gamepad off super quick. (Leaves the console to boot normally but it is off).

#2 I tried that, but to no avail. I still couldn't control anything with the pro controller.

#3 I will try that out. thank you.
