Thanks for your interest in Lumion.
The maximum output is set to Poster 7680x4320.
Allowing user input of other resolution sizes and/or scale has been suggested by other users and is in the wishlists.
There are 2 possible workarounds to resolution size:
1. Use a photo editing tool that is capable of re-scaling images to higher sizes. For example this free one: SmillaEnlarger
2. One of our users also shows how to render parts of a view, and then stitch those together in an image editor for very large resolutions.
