Different screen resolution/sizes ?

On some laptops with screen resolutions smaller than 1920 x 1200, this test app is missing its life bar and even the empty space is showing to the left next to the background. How do I ensure my app will have same size for all screen resolutions, the way I designed it on my pc with a 3840 x 2160 screen resolution?

Imagine video games/programs where the HUD layout are proportionally scaled to individual screen sizes instead of being messed up or leaning towards one side.
