Constructor & Destructor Documentation

DisplaySettingsTab()

DisplaySettingsTab::DisplaySettingsTab	(	QWidget *	parent = 0,
		const char *	name = 0 )

We hide the HDR page in Wayland mode, because the mode is managed by a different page. We still keep the disabled tab visible on other systems just to promote the existence of this feature.
