You still see an overlay of the control when you you set something. E.g. if you turn up the volume, you see the volume bar over the picture, If you turn on AirCon you get the appropriatte symbol. These are different images to that of the 'normal' display and are only displayed for a few seconds. A quick question/s about the video select switch, If I short out this pin does the overlay superimpose over the TV picture when I change an A/C control etc? If so, do we need a switch or can we just short this pin to ground? What happens if the STB is turned off, does the display return to normal? Do you have any photos of the display with the overlay superimposed over the TV picture? I would be keen to see it. Thanks
