You seem to really have bad luck. High DPI works without a glitch¹ on all of our developer machines², most of them using two 4k monitors in parallel.

¹ both on Wayland and X11, so maybe we're really being lucky.

² mostly Dell Laptops, but also Lenovo

Can you do 150% fractional scaling on a 27" 4K monitor in any Gnome based desktop?

Dell? I have a cupboard full of ones I've murdered and a limping one. No thanks.
