iMacHigh Sierra (late 2012), 27″ 2.9Ghz inTel Core i5, NvidiaGTX 660M 512 MB 24Gb memory 1600Mhz DDR3. Second Monitor LG.
Apps are VLC, Elmedia Player, QuickTime,DVDPlayer (Apple)
Instead of showing a static photo on my second, extended monitor (LG), I would like to be able to play videos and slideshows. I would categorise them in different Playlists, like Music Videos of my favourite performers (e.g.downloaded rom Youtube), Videos about nature (from BabaMail) and Arts (from various websites), my own home movies(PowerDirector, iMovie, iSkyVideo) and slideshows (Keynote, Moviemaker,Windows Powerrpoint).Most of these files are now in my iMac Folders of Documents, Pictures and Movies, but I can of course move them all in one Playlist folder, after converting their different formats to one and the same (if necessary). From there I would choose a Playlist to run the herein contained videos/slideshows. All have audio (music or narration).
Thanks for your advice, Gary!
