Detailed Description

MythDisplayRPI uses Broadcom specific APIs to access display information and set the current video mode. It should be used when an X11 display is not present (MythDisplayX11 will offer complete functionality) and is preferred to MythDisplayDRM - which currently has no mode switching functionality.

Note: MythDisplayRPI only supports changing the display refresh rate and not the resolution. All video modes that do not match the resolution at start up will be filtered out. This is because when X11 is not available, the APIs in use will 'undercut' Qt's display handling i.e. Qt will not be aware that the video mode has been changed and it will not create a new framebuffer of the correct size.

◆ UpdateCurrentMode()
