> Neither of your monitors requires HiDPI scaling
I beg to differ, 4k/32 does need scaling to my eyes. I don't want things to be that tiny.
Not every application needs to support scaling, so long as the GUI framework they use does, and the window manager does (XFCE has support, which I have activated) that makes the 4K screen more usable to me (while allowing the full res to be used for smooth rendering), then I use xrandr to scale the lower-dpi screen back down so elements are the same size across both. Sure, there are a few apps that don't behave brilliantly, but they aren't things I use much.
Like I said, it works better for me than MacOS or Windows (I have both, and a 2103 Retina MBP I still use).

Of course I meant a 2013 rMBP, I'm not a time traveller :)
I'm still impressed that it can do its scaling stuff on a 4K screen, using onboard intel iris graphics. It's been a great investment that little machine.
You didn't understand the problem mentioned by GP. Neither of your monitors requires HiDPI scaling. Your first monitor has approximately 138 dpi and the second a paltry 94 dpi.
Compare that to a 2012 MacBook Pro that has a 15.4-inch display with a 2880x1800 resolution. That's 221 dpi. The hallmark of a HiDPI is that its DPI is so high that you need to render UI elements at 2x or more (though sometimes 1.5x also works), so that originally a one-pixel line becomes two pixels wide. This requires support not just in drivers and the OS, but the application. ArchLinux has an entire wiki page discussing application support: https://wiki.archlinux.org/index.php/HiDPI
