Image does not fit in full screen.

    Hi everyone, I start with Libreelec this week in my rpi4, seeking for an alternative to LG TV share software, because my TV does not decod HD audio.
    So, I plan to use the rpi4 with two HDMI, one to the receiver (my receiver does not handle 4k) and another to the TV.

    This worked fine without problemas.

    But the image at TV does not fit fill screen, there is some black pixels on the left of the screen.

    I choosed the 3840x2160 pixel resolution, TV is in Pan Scan (don't know why I can´'t change it).

    I select Zoom at the imagem adjust in Kodi and fit the sreem, but I don´t know if it´'s right.

    At the TV é can see that the input resolution is correct.

    And I don´'t know with Kodi give the option of 4096 x 2160 pixels.

    Anyone saw that before?

    Tonight I can post a picture here.

    Thank you for the help.

    Your TV should be able to display the RPi4's picture 1-on-1 pixel perfect. All TVs have a setting to disable "overscan". With LG this is called "Scanning" on my TV, but LG can have renamed it by now. Only as a last resort should you use Kodi's calibration settings.
