Picture in top left hand corner (SOLVED)

I got a new Samsung 55 inch QN90B neo QLED tv and started having a problem with a small picture in the top left hand corner of the screen every morning.

Initially, to fix it it required a reboot of the Arris DVR or going to settings on the DVR and switching to 480p res and then back to 1080p.

After many days of experimentation, I found that by disconnecting the HDMI cable to the TV overnight during the daily update, the problem did not occur.

So the conclusion I came to was that there is some kind of interaction bewtween the tv and dvr box during the daily update.

To isolate the TV from the DVR, I decide to purchase a HDMI splitter from Amazon for around $20.  I connected the DVR HDMI output cable into the splitter input and  connected  one of the splitters outputs to the one of the TVs HDMI inputs.

This apparently did isolate the interaction between the TV and DVR during daily updates and cured the problem.
