Enabling GPU scaling allows you to increase or decrease the size of an image on your screen while keeping the same aspect ratio. This can be useful if you’re using a resolution higher than your monitor’s native resolution.
You can usually find GPU scaling options in your graphics card control panel, or by right-clicking on your desktop and selecting “Nvidia Control Panel” if you have an Nvidia GPU. If you have another brand, you likely will need to download their proprietary software.
