Is there any adjustive(or automatic) viewport size?

[TheoKim]

Hello, I'm wondering if there's a way to automatically adjust the viewport height for browser prototypes.

Currently, I'm using two different types of monitors: 2560*1440 (16:9) and 2880*1800 (16:10). Each time, I need to manually change the viewport height to make it fit in properly. If there's any method to set the 'viewport height' to 'automatic' or 'adjust to browser', I'd greatly appreciate your help. Thank you!

Unfortunately the artboard size is fixed and cannot adjust itself to match the viewport.
