Taking a really high res image?

Hello, how would you take a really high resolution image of a map even if your monitor is only 1920x1080. I’ve seen people do it but don’t know how :frowning:
Thanks!

Solved, use the command poster so like

poster 8

will take an image 8x your screen resolution.

solved

another good way to do it

Pfft too hard for my laziness

The mark as solved option isn’t coming up :-/

mass select, drag, drop, save as png, done
