How to disable Pro features during the trial?

[gerchicov-vg]

I'm not sure I am able to purchase a pro version due to some circumstances. So I want to check capabilities of the free version but you doesn't allow that because you have enabled trial by default.
In my particular case my default display is detected as generic and it makes fullhd resolution the only option available. I found out that I can at least create a virtual screen with custom aspect ratio and then change screen resolution in system settings but I don't know if it is free or not according to your list:

Could you please do something with it?

Sure, just go to Settings > Application > Advanced… and turn off Licensing & Pro Features.
