To start with, I’m not sure whether the on screen clock is supplied by the TV or box, but I’m guessing the box. Somehow, we’ve lost the clock and I can’t see any relevant controls within any of the tools/set ups etc. Could someone point me in the correct direction please?
Would normally be an option on the TV overlaid on any video source or using the TV tuner. Try the TV remote info (i) button or the TV setup menu options.
