Disable display, force screen saver - DVDA, BDMV,

Is there a way to disable the display, while letting audio continue? or Have audio (from a “video”) play in the background?

There is some audio only DVD-Video content or audio-only Blu-Rays that still have “video” portion.  Some video portions remain blank, which is fine.  Others display a static image.  For example, The Beatles - Love album, has a bright orange/yellow background with the song title. 

Thanks

Unfortunately, as far as I know, no, this is not possible.
