My HP LA2205wg monitor has at least second delay in switching
resolution, and KDE desktop takes another second to re-layout
desktop (large number of app windows etc) after resolution switch.

Where do you get 312 height for 1x Atari resolution?
AFAIK Atari ST/e cannot support that high low/med overscan
resolution.

There's no standard mode for that, so I doubt your LCD
monitor supports such thing. See:

Is your monitor 4:3?

Hatari gets resolution list from SDL, which queries it from
the underlying system.  If either your monitor, or OS display
manager don't support 400x300, you're not getting it.

I removed that heading from the SDL GUI and added ST/e option
for desktop resolution + moved the options around a bit in
the help output.  Hopefully that does what you wanted.
