back in 2009, the d-fuser was conceived to mix ‘triplehead’ dvi. it was a direct need for d-fuse’s live shows, along with HD. that story is long told.
then in 2011, the datapath X4 was released. it’s a triplehead2go on steroids, coming from the pro-av market rather than gamers. still, surprisingly affordable for what you get, which is a 1-in, 4-out dual-link dvi box where each output is completely configurable. before even getting to running quad-head, you could take triplehead input, split that to three outputs, and then use the forth to scale that non-standard 12x3 input back to something you could display on a monitor on your desk. i like, a lot1.
it was a while until we got our hands on one at d-fuse HQ, but we did, and *spark d-fuser, meet datapath x4. quite the upgrade from a triplehead2go. pic.twitter.com/9BZuKhJrcu

so - attached is a zip of files with the resources you need to configure 2048x1536@30Hz through your d-fuser and 2048x1536@30Hz to 4x 1024x768@60Hz through the X4.

i didn’t see many config scripts for the X4 when i wrote my first, so here’s the configure script from the zip in plain, google-searchable, text.
