Get Supported Fullscreen Resolutions Not Working

I´ve followed many tutorials searching for a solution, i just created the nodes as you can see in the image below. My Combo Box is empty (in creation), and still empty even with this nodes running. Tested also debbuging putting a print right after the “Event Construct”, and i don´t know why is not working at all.

Thanks in advance.

Oh, and it´s giving 0x0 as response if i try to print.

I have found out what is the problem. It´s because i´m working on a notebook. I tried to create in a desktop, and worked. I think this is a problem that i couldn´t solve without a software update i suppose.
