The standard approach for a video wall is to use 1 SignStix
player per panel. This is because the maximum pixels a M12S player can decode
is 1920 x 1080. However, this may still be possible using a HDMI splitter and
would require testing. In the below scenario the resolution is 1920 x 2160. If
applying a video, the best
option may be to leave SignStix in landscape mode and pre-rotate the video
(either prior to upload, or using SignStix 'Convert to Portrait' upload
profile).
