I use a Lenovo X390, MX-Linux 21.3, with one user using xfce (the "original" DE) and the other using TDE.
When I plug in HDMI (for a beamer, in this case), xfce can easily be set up to mirror the display.
When I use TDE and connect the Beamer (seen as HDMI-2), TDE automatically extends my screen to the beamer. xrandr -- output HDMI-2 --same-as eDP1 (where eDP-1 is the internal screen) does mirror the screen, but it remains extended.
Now if I run "Configure Displays" and select "Enable local Display control for this session" (which was not activated), I do get the mirroring I am looking for. But if I click "Apply" the screen turn to psychedelic colours - seems to be wating for me to validate the choice, what I can't do and anyway would not as it's unusable. After a while the sceens returns to my desktop, albeit stil psychedelic, and I must log out / log in to get my desktop back.
So for the time being that means I have to use xfce when I need the beamer.
Anyone knows what's going on and what I should do to mirror my 1920x1080 screen to the HDMI beamer?

This is a known major bug and has already been reported.
https://mirror.git.trinitydesktop.org/gitea/TDE/tdebase/issues/163
Unfortunately we still don't know the cause. Apparently the display configuration module somehow messes up while trying to set the settings with XRandR.
Meanwhile you can use another tool like LXrandr or the CLI. I have also written a small TDE app for my own needs with three simple options, disable HDMI, mirror and extend (side of screen selectable). It is a wrapper around the xrandr tool so it shouldn't mess up anything:

Hi Philippe, how about we add tde-easy-projector to TDE? It may be a temporary thing, till the time we fix the real issue, but sure it would be quite useful for users. What do you think? Cheers Michele

What graphics chip(s) in yours?
MX-Linux 21.3, with one user using xfce (the "original" DE)
What doc(s) establish that? It could depend on how original is defined. If going by available official 1.0 release, then it seems clear that it is. If it's defined by initial downloadable pre-alpha for looksee, then it's not clear based on the looking I did. If defined by project start, then either it or KDE could be the title holder. All I've found for project start dates are "late 1996" for both. I was quite surprised to learn "original" release of Gnome wasn't until after both, in 1999.

As a doc for FVWM it has come a long way :) I had tried it some decade go, but (like windowmaker) it did not stick. That time the "original" CDE was still around and the new clone did not come up to the original. Other WMs of the time like OpenView were way more intriguing. There's a clone more close to the original (based on fvwm) called NsCDE https://github.com/NsCDE/NsCDE - just if you are curious.

FWIW I use T-Menu / System / Screen Size & Rotate to position my three displays and things work fine provided the Brightness and Gamma controls are on default (all 2.2). Any gamma deviation from default and it looks like a bad CGA display and I have to reboot (or run the NVidia X Server Settings tool which also manages to fix whatever broke).
