"Watch in HD" popup

[Black Hole]

I have my boxes connected to the TVs by HDMI, but I also have RCA connections coming out of the back of each which I sometimes connect to cheap monitors from Amazon, intended for car reversing cameras. These allow me to keep an eye on what is happening onscreen without tying up the TV.

The point I am working up to is that I haven’t seen this pop up for years. I thought it had been discontinued in someway. I now appears that RCA connection maybe sufficient to block the message. If I get a chance I will experiment.

The HDR-FOX "knows" if you are taking a feed from SCART/RCA and refuses to simultaneously output HiDef to HDMI, so there is a good chance that's right.
