I get a issue when switching HDMI inputs on my tv back to the HDR after using my xbox when the HDR is recording whereby the display will flash up for a millisecond and then go blank for around 5 seconds and repeat.
This seems to be indicative of the HDMI negotiation failing.
To resolve it, I put the box in and out of (soft) standby which must reset the negotiation.
Question is though, is this my box or the TV? I would think it is the box. And if it is the box, is it firmware or hardware that's at fault?
The TV in question is a Samsung PS42C450 on the latest firmware.
