i have digital/analogue (hybrid) tuner, got it on ebay off a seller in germany, about 6-8 years ago... no good in the US anymore, as we managed (again) to come up with our own digital standard... however, it is still good for a reverse camera and the AV inputs...

the SET in mine actually has an option for a 4:3 or 16:9... could it be that the monitor is not sending identifier over the ibus, that the monitor is a widescreen? i wonder, how that can be rectified...
