Working on an upcoming project where I want to send content to three 4K monitors in a 1x3 arrangement. For those who have tried this thing before, is there any benefit to rendering the 2 minute source video as separate 4K files versus making an 8K canvas and rendering the content as a single tiled image? I should be able to split 4k windows out to the monitors in BA either way, just wondering if there's a preferred methodology for this. Guessing that file read data rates could be a factor, but unsure if the 4055 hardware cares at this level.

Bright Scripters I'd always prefer to work with a single file vs. multiple.
The multi HDMI outputs players make it very easy.
Are you looking to create a video-wall effect where a single image is spanned across multiple monitors?
Here is a tip; you don't have to author the full 8K frame. You can play files with smaller frame size.
Stacked
3840 x ( 3 * 2160 ) -> 3840 x 6480px
In-Line
( 3840 * 3 ) x 2160 -> 11520 x 2160px

John Rucker It's an effect built into scenery. Will have three monitors in a row with some space between them.
Good call on the custom frame size. We'll go with that and I'll have the video team render as a single file. Thanks!

Bright Scripters If you have diagonal lines or curves going between the monitors, the video would need to "remove" part of the image to compensate for the space between the monitors. A frontal picture of the physical installation, can help them as reference.

ProVizion LED Signs Good advice above. One more thing from the video wall side: since your three monitors have physical space between them, make sure the video team accounts for the bezels and gaps in the render — not just the 11520x2160 canvas, but the actual dead space where the bezels sit. If content spans the gap without compensation, straight lines and motion will look broken at the seams. Most video wall setups handle bezel compensation in the processor, but since you're rendering a single file, it's worth baking the gap into the artwork itself. Also colour-match the three panels before final install — even identical models can drift, and a 1x3 wall shows mismatches mercilessly.
