 			If [code]true[/code], allows HiDPI display on Windows, macOS, Android, iOS and Web. If [code]false[/code], the platform's low-DPI fallback will be used on HiDPI displays, which causes the window to be displayed in a blurry or pixelated manner (and can cause various window management bugs). Therefore, it is recommended to make your project scale to [url=$DOCS_URL/tutorials/rendering/multiple_resolutions.html]multiple resolutions[/url] instead of disabling this setting.
 			[b]Note:[/b] This setting has no effect on Linux as DPI-awareness fallbacks are not supported there.
