S240HL Monitor powers down on return from sleep mode

My S240HL is connected by HDMI to a Windows 10 pc with an AMD graphics setup.  On return from sleep mode, the monitor appears to come out of standby (blue LED) but after a few seconds switches off completely.  Monitor will not switch on via the switch, but starts up if the power cable is removed and re-inserted.

 

This monitor has shown the same behaviour when connected via DVI to another Win10 pc with an NVidia graphics card.

 

Any clues, please?
