Game not showing full screen..

So I had someone design me a 2D game in Unity… he did the main work and my friend is going to do the graphiccs, and we’ll add sound and stuff.

So, he delivers me a build (exe) and source code. I run Windows 10, and have dual 27" monitors… 1920x1080. The game runs at 1080x1920, so I set the main monitor to portrait mode and run it…

It only displays in the middle of the screen… the top and button of my game are cut off… black bars on the screen…

Anyone know how I can fix this so I can test the game out fully? I mean, I tried the game briefly, but I can’t really test it if I can’t see it all.

The person who designed the game for me it works fine for him, and he sent me some video of it running. He made it using 2019.3.f71.

Look for a canvas scaler component on the main canvas (near the top of the hierachy) and play with the settings there.
