Soldato
Oh I've also found that there are two strong magnets on the underside of the monitor. not sure what use they serve but my magnetic tail-capped torch has a convenient place to keep itself stored now and the USB port on the monitor makes for easy charging too lol:
Both magnets are in the same position on the left and right of the monitor's underside. Def magnets not pieces of metal chassis because the torch repels on one end of each magnet.
IIRC Dell do a magnetic soundbar/monitor speakers, so it might be for that?
