Are you sure nothing is setting DPI explicitly or implicitly, such as your DE?

Using which video driver? All FOSS driver versions I've used since long before this bug was opened force 96 unless unless explicitly overridden via xrandr, Xft.dpi, server startup option -dpi, DE settings (which typically use Xft.dpi or xrandr), or xorg.conf*'s DisplaySize option. All these options force a specific DPI. None enable the server or driver to do what computers do best, calculate and apply an accurate value automatically, which is what this bug is effectively requesting.
