I'm looking for the simplest way to create a 1x3 landscape video wall. Where the animation plays at 5760×1080 across the three screens.
The orientation is like this: I've seen PiWall and that might do what I need (although seems to max out at 1920×1080 total resolution) but if there was some sort of HDMI splitter solution that works like this it would be great and could just run off a laptop. But I feel like a lot of them just clone screens as opposed to the video wall effect?
The screens are three consumer LG 55UK6470PLC TVs. I see there is an LG SuperSign software to do with WebOS for creating video walls but can't get hold of anyone in LG to confirm or deny that it would work with our screens. And I can't find it to download anywhere.
Any advice or help would be appreciated.
