Hi,
I recently received and Xbox one and following the instructions the xbox one has 2 HDMI slots, 1 for the Cable inbut the other goes to the TV. I am getting a constant flickering on the screen when viewing tv thru the xbox one console.
I was informed to ask this.
When you assured that the cables are all undamaged, plugged in correctly and support the Xbox One (you should make sure they relatively new and have big throughput) and it still doesn't work you should ask Verizon whether their box supports HDMI passthrough as some boxes will block signals with HDCP once a device comes between them and the TV.
does anyone know if the Verizon FIos DVR 500 GB box QIP-7232 allows HDMI passthru?
