I have a Mac Mini connected to a Sony W755C TV by HDMI. If I put "Set display to sleep" on the Mac, the TV goes to black but displaying a very unsightly OSD text "HDMI 1 (Clock) No input. Check your cables, etc." which stays on forever, until I power the TV off manually. I can't find any menu items in the TV to remove the OSD, which just looks ugly on the huge TV in my living room.
So I tried to use the TV's own "standby if inactive for n hours", but "inactive" for the TV means not fiddling with the remote, which I only use for ON/OFF. The TV is oblivious to what's going on on the Mac. So it will suddenly suggest to sleep in the midst of a movie, which is obviously annoying.
Is there any way I can make the TV either a) go to standby modus without any OSD text, or b) soft-power off (same as pressing OFF on the remote — which is not full power off, mind you…)
