If you go to output mode to the top and select advanced, you'll have a lot more options like mine. This gives a lot of leeway to having more control of whatever you're outputting. IMO I think 40k bitrate is a lot for 1080p and maybe more or less 1440p, but that's just my OP.
You can change your base (canvas) resolution to 1920x1080 so it maintains the 16:9 aspect ratio when scaling, and then use the scaled resolution for what you're outputting it for. Like 2k, 4k, which you look up the resolution sizes on Google. You can disable the option for "rescale output" in your first screenshot and just use the video settings as it's a global setting.This is my advance setting -![]()

I never used this btw so I have no idea how this will perform.
My resolution is exactly 1600x1200 (goes for my monitor as well with 60hz Its bad I know)
