i had the idea to add a option in the menu, for the possibility to change the render resolution.
So we can force the render resolution for every host.
A system with raspberry can have some issues with fullhd. So we can reduce the rendering from fullhd to 720p or lower.
Some people have some problemes with 4k TV´s (like me) too. With blackscreens, slow menu and others.
With that option it is easier to change the resolution without using xrandr.
Sorry for my english, it is not the best, i know it
