Dual monitor mirroring with different resolutions

Q&A
1

I have in Gnome Wayland two monitors attached to a Intel NUC8i7BEH. One via HDMI. One by USB Type C alternate mode on Thunderbolt 3 port. HDMI is a monitor Acer ET322QK. USB alternate mode is a Faytech lapscreen 10-Point-Multi-Touch-Version.

Using dual monitor extended mode:
xrandr --query
Screen 0: minimum 320 x 200, current 5760 x 2160, maximum 8192 x 8192
XWAYLAND0 connected 3840x2160+0+0 (normal left inverted right x axis y axis) 700mm x 390mm
3840x2160 59.98*+
XWAYLAND1 connected 1920x1080+3840+0 (normal left inverted right x axis y axis) 470mm x 260mm
1920x1080 59.96*+

How can I use mirroring (cloning) with same set-up having HDMI 3840x2160 scaling 200 percent and
1920x1080 100percent?

I’ve never heard of this being possible (maybe it is).

Buuuuuuuut

Why don’t you set the 4k screen to 1080p so that the resolutions are identical instead?

Setting the 4k screen to 1920x1080 fonts are not sharp. Less readable. It seems to me I need new glasses

I see, yes, that would likely happen if the monitor does scaling with a filter and not just pixel doubling.
