Flamingo nXt 5.5 - Can't change render resolution or quality


I am unable to change my flamingo render resolution and quality in any way by adjusting the settings in the render panel on the right side of the screen. The only two options that actually do anything are Viewport dimensions, or, if I select any other dimension, it renders at 640 x 480, or close enough, every single time, no matter the selection.

Is there something I’m missing? Changing DPI, Quality, entering a manual dimension… nothing seems to change my output.

Running Rhino 6, Flamingo nXt 5.5

Thank you!

EDIT: Seems I am able to change some of this in the actual Flamingo tab on the right, the render tab isn’t “overriding” what the Flamingo tab has. So, that has allowed to me to change resolution, but now I can’t change the DPI. It’s just grayed out, and resolution just says “Display” and is also grayed out. I’d like to get a few renders at a higher quality than my display can… display. How do I change this PPI?
