With the latest firmware that was released for Samsung QB series displays in December of 2024, there is a bug in portrait mode when showing videos. The videos appear to have a gray line at the bottom and a black line on the side.
We have created a ticket on Samsung partner site and they are working on fixing it. We will provide updates as soon as new firmware is released.
Starting version 4.6.4, it's possible to choose the media player backend for Samsung Tizen devices. Up until now the videos were played by the HTML <video> player, but that had some limitations especially in the portait mode. With the AVPlay API, our software gets lower level access to the video player internals and thus we can make additional optimisations.
We will be rolling out the release gradually, if you wish to update right away, go to https://my.playsignage.com, open up the screen settings and click "check for updates"
