How to turn off the HDMI2 popup that keeps happening every 15 minutes?

Question

I purchased a LG OLED TV in December 2017.  It is great, except for one annoyance. Every 15 minutes, a  HDMI2 popup appears in the center of the screen. It disappears after a few seconds.  This repeats ad infinitum.  My TV connections are  very simple.  One coax cable input to the Cable Box.   HDMI output from the Cable Box  to the TV's HDMI1 input.   The coax output from the Cable Box is connected to a Magnavox DVR.  The DVR is connected to the TV's  HDMI2 input .   The DVR is "off" when we watch normal TV on the HDMI1.   I've searched the internet for a solution, without success.  Any ideas?

That pops up when a devices screen changes, which is connected to hdmi2. I am not to sure how to turn it off but it might be the dvr sending some sort of Audio or visual output. Turn off the dvr at the plug and it shouldn’t do that.

      I've had an LG 47LB6500 for about five months now. I love the TV and it's great. Except one thing that I find irritating is a constant AV input popup that keeps reappearing over, and over, and over.
       
      While watching any content from any input, the popup appears. This image is one example of it, inside the Netflix app.
       
      The only device plugged to the TV is an HDMI Sky HDTV Set Top Box, and there is nothing plugged into any AV input. WebOS seems to enter some variable loop, displaying several of these popups in sequence. Often, the number of popups is such, that the TV will freeze trying to show all of them. I can only assume a lot of its CPU is being used to render them. The TV will become unresponsive until all popups disappear. The annoyance may last a couple of minutes, but it happens everytime the TV is turned back on.
       
      From the input configuration screen, I can see the AV input is active. And I can try and remove it from the list of inputs.
       
      Once it's removed, the popups are gone. But once the TV is turned off and back on, WebOS will scan for devices and these empty AV inputs are back on the list... and the parade of popups will follow.
       
      As a user, I have to consder this a bug. And it's a very irritating one. These popups cover subtitles and seem to show up minutes after the TV is turned on. Please provide a fix with a firmware update or, at least, provide a workaround to make it stop.
       
      Kind regards!
      Julio
