How to create giant bitmaps such as for backgrounds?

I've seen a few hints here and there about multiple textures, but can't find a consolidated answer I can comprehend! Let's say I want a pixel-perfect, 2x2 screen bitmap background for a 1080p target. That's a bitmap that'd be 3840 x 2160 pixels. The largest texture resolution I can use on mobile is 1024x1024 for universal compatibility. So I'd have to stitch bitmaps (4x2 with a bit of scaling) together. Using separate quads doesn't work as there's a seam. And layering textures doesn't blend correctly with what I've tried. So how's it done?

Are you sure about the "would be a seam" part? I created a 2D side-scroller, and have seen others, and there was no seem between the (several hundred) small blocks... at least not once I figured out to change the texture to Point Filter ins$$anonymous$$d of Bilinear.
