LG 47LK530T LCD screen disable shut down?

[exim]

Hello. We've recently had installed LG 47LK530T LCDs as Digital Signage screens, but they seem to shut off after a while and you must manually switch on the screen again.

 

I expected them to work the same way as our Samsungs, which auto detect the VGA signal from the signage box thus turning themselves on/off accordingly.

 

Anyone aware of any mode or setting that can resolve this? I've already scrutinised through the manual and menus. Perhaps there's a hidden service menu?

... nevermind I've sorted it. There was a clear setting to use in the Time menu! lol.

It was not mentioned in the manual though.
