Hi @Rapi,
Thanks for bringing this issue to our attention.
May we ask if the display issue is persistent with the Netflix app only? If so, kindly try to perform the correct order to reboot this app by removing the channel, restarting the device, and adding the channel. You can also try to check for the channel's update by clicking the star button on your remote. Ultimately, during playback, click on the star button for additional picture settings within the app.
Please keep us posted.
Regards,
Janadee
