Size of flamingo nxt render window / picture

Rendering Flamingo
1

Where to find the command for increasing the size of the render picture (Flamingo nxt)? I have been busy to find - but couldn´t find yet.

That’s in the Flamingo nXt control panel accessed from the Flamingo nXt drop down menu. Then look in the Render section.

Thank you for your help. Kind regards.Michael
