Picture in top left corner

We've been having a constant problem we can't seem to fix.  When turning on the TV, the entire picture is miniature and at the top left corner. The TV itself works fine when we launch apple tv or another streaming service, but when using the cable box, this is what happens.  There is no other way to fix other than reboot the contour box by unplugging and re-plugging back in.  Cox doesn't know what the issue is either.  Anyone else experiencing?

  • I have experienced this myself recently. I have had the same cable box and hdmi cable for a few years and did not start seeing this occur until I bought a new TV a few months ago. The only workaround I have seen myself outside of rebooting the box like you say is to change the display format to a 480 format and then change it back to 1080p in the contour settings menu. I have a Samsung QLED model Q80B. I had a different Samsung prior to this (non-QLED) and it worked without any issue. I think this may be a hdmi handshake issue as bluestar mentioned.

      Thanks for the input. Trying a new HDMI cable and will give feedback after some time.

    If HDMI connection, sounds like a handshake issue.  Try different input on TV and/or a different HDMI cable.

    What manufacture TV do you have? Do you have anything else plugged into it for HDMI? Sounds like either the TV or the box is going to screensaver mode.

    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.
