How do you set the resolution in UE5?

Basically I tried different tutorials for changing the resolution but nothing changes. I’m the trying to set it to 640x480 fullscreen with two black bars.



What am I doing wrong? Is there a Settings Menu for the Level where I change the resolution?
Thank you

maybe it works with appropriate device. So you would like to test at the right device which has 640 x 480 resolution.You can’t test it 1920 x 1080 kinds of general desktop.

Or try this logic.
First, Add config files in your root directory.

Second, Try this blueprint on Level blueprint or something ( You can edit 640 x 480 )

Third. Have a test. On device having resolution that you want.
it works well.
