Yeah, I've got it them showing up correctly now! I use a canvas in Photoshop that's the resolution of my Ultrawide monitor, scale the horizontal down to 1920, place a line shape in the size of what's in the other configuration and in the same x placement, then scale it back up to 3440 and get the numbers I need for my setup. And then the same for the vertical, which I only had to do for BattleZone.
