Interference with xbox one. When my son turns on his xbox one there are a series of signals across about 30hz apart of course I see it on my screen with this beautiful 6300. Will try to capture it somehow. Has anyone come across this interference?
Does the Xbox have a wall-wart supply? change it to an analog one if you can. Then beef up all the in and out cabling, especially the HDMI and power leads. Ferrites on them all (you can never have too many). You might also want to see what can be done about internal RF suppression. Metal tape (from Home Depot, etc) can be used to great benefit on plastic cases as long as you're careful about ventilation.
Of course, you could go all legal on him and tell him that he must cease operation due to interference caused to your licensed installation. Good luck with that, Dad.
