Xft.dpi is the foundation on which Gnome/GTK built its zoom knob. You should try
incorporating it instead of kludging around it. Set it in Xresources (or TDE
desktop settings if it offers something close enough to what Xorg is or you
want) to whatever DPI number xdpyinfo or tdecmshell xserver reports and work
from there, keeping resolution at your display's native.
