I’m hoping someone can help me figure this out. I have a media player connected to a 1x3 HDMI splitter, and each output goes to a vertical (portrait-oriented) TV. All three TVs show the same full signal from the media player.
What I want is for each TV to display a different video—almost like they're three separate screens playing different content—but the splitter only sends a single HDMI feed.
My questions:
How do I design the video file so that each of the three vertical TVs shows its own section of the video? Do I need to create one large video that contains three smaller videos side-by-side, each rotated for portrait orientation? If so, what resolution should the master video be, and how do I account for rotation/positioning so it maps correctly to each TV? If anyone has experience with splitters, video walls, or designing mapped video content, I’d really appreciate guidance. I’m not sure if I’m approaching this the right way.
Last year, I did this with 4 TVs and this was the video I made. Not sure what I would do with 3 TVs.
