Question Each time it runs, the game's window is small

I'm a raw recruit to unity. In the picture below, every time I run it, I just have this little screen that doesn't fit with the screen resolution, and this is what the .exe file looks like when it opens, the same thing. How can I adjust this window, please? (ㄒoㄒ)

 

Camera and canvas settings look fine. The reason is probably because the elements on the canvas have a fixed size.

Can you send a rect transform of one of the canvas elements (first in hierarchy of canvas)?

 

Thanks for your reply. Here it is.

 

1. Check what you have set in Project Settings. Search phrase (upper right corner of the phrase field) use Default Is Native Resolution.
2. If everything is fine there, check the game preview again. Change the settings from Free Aspect to Full HD and see how it looks at this resolution (is it the same effect as after compilation).

 

I've tried your advise, but sadly, the setting is chosen. And the game preview doesn't affect the actual performance.

 

I wonder if I chose a genre other than a 2D project when I created this project, causing unity to be built at some sort of fixed resolution. Other projects I've created don't have this problem.

 

Probably a daft question, but what's it supposed to be? If you don't mind me asking?

 

After running the.exe file it should present a full-screen scene, but not black at all corners.
