no, not out of the box. But you could go with some scripting.

Place a bash script into .xinitrc or into .config/autostart/ which:

1. detects monitor size with xpdyinfo or xrandr as mentioned here:

2. runs "xfconf-query -c xsettings -p /Xft/DPI -s <your preferred dpi>"
depending on the previously detected resolution.

I'd recommend you to set different themes for Gtk and window borders as
well to avoid small UI elements.
