Need higher resolution image for Knowledge Map

This is my MSR industry Knowledge Map. It's getting a bit crowded. It would help if I could export a higher resolution image than 1920x1080. This is from a screen capture with Desktop Browser running (after a LOT of dragging nodes around.) Does Browser export image files?

Any Bloom tutorials that show how to display all the nodes and relationships and output an image. Having a tough time finding a Bloom tutorial on this.

Thanks.

No help yet. Anybody?
