I have a Dell S2240L connected to a laptop by HDMI. It was made in 2013 in China. After switching off the computer, the monitor shows "No HDMI Cable  - The display will go into Power Save Mode in 5 minutes"; after the countdown expires the monitor finally enters standby. How can I get the S2240L to enter standby just after the PC switches off (i.e. no countdown)?
S2240L, disable Power Save Mode in 5 minutes?
