zoom level changes between map sizes

Hey everyone, just trying to troubleshoot a small issue.

When I start a 1v1 game the level of zoom and resolution is perfect, however if I switch to a 4v4 large map, I'm too far zoomed out. I'm assuming it is something weird in my settings?

I don't have the enhanced graphics pack enabled.

Settings are:

Display Mode: Fullscreen

Resolution: 1920 x 1080 (Scaled up to screen)

Zoom level: 100% zoom out.

​

Any insight would be appreciated! Its a slight annoyance to manually zoom in every time I switch to team game.
