webOS 4.1 and 6.0 cannot play UHD/4K videos in a gapless manner

Due to performance limitations of the display, LG webOS 4.1 and webOS 6.0 cannot play UHD videos in a gapless manner.

This is an HW limitation that cannot be adjusted by signageOS.

To play UHD videos on this model, omit using sos.video.prepare() otherwise, your videos will turn black.
