If you use Xfce, you can make your display bigger than its maximum resolution by using scale in display settings. Chose "Custom" and set it to 0.5/below. Don't set it to above 1 because it will make your display smaller and don't set it too low because it will make your display blurry. If you encounter an issue when play game, you must revert your setting.
You can do this too with xrandr but i don't know if this will work in desktop environment. You may try it if you want. I never try this with wayland.
Sorry if my english is wrong
Edit: change 0.9 to 0.5.
