Michael Ausec posted a question in LG webOS Smart TV QuestionsI 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?
