when i use the "xrandr" command, i get the following output:

Screen 0: minimum 16 x 16, current 1366 x 768, maximum 32767 x 32767

and when i use
"xrandr --addmode HDMI-1-1 1280x800_60.00"

i get the following output
"xrandr: cannot find output "HDMI-1-1"

help out and let me understand where i went wrong
Thank you :)

Gives error on :
$ xrandr --output HDMI-1 --mode 832x396_30.00 --right-of eDP-1
xrandr: Configure crtc 1 failed

Use '-clip xinerama0' to clip to the first xinerama
sub-screen (if xinerama is active).  xinerama1 for the
2nd sub-screen, etc.  This way you don't need to figure
out the WxH+X+Y of the desired xinerama sub-screen.
screens are sorted in increasing distance from the
(0,0) origin (I.e. not the Xserver's order).

Ought to be xinerama1 for the common use case of no other screen being connected (and easily adjusted for other setups), which makes the whole script a lot more more robust.

Thank you very much for providing the expertise shared here!

I find the connection via ADB rather slow. If I use screen mirroring via the tigervnc-scraping-server running x0vncserver, the connection is fast. Any spontaneous ideas in terms of how to improve the speed in your setup would be welcome.

What I am really interested in is to use a tablet as secondary display on a teleprompter in a video conference (setup like this: https://www.youtube.com/watch?v=ScnXGRLugVk). The problem is to mirror flip the display. Of course, this is possible with an HDMI camera field monitor, but that is much less travel friendly and versatile compared to an android tablet.

One can use VNC via ADB but it seems next to impossible to mirror flip the image. xrandr -x does turn the display, but only locally, not via VNC. Android VNC clients able to mirror flip on the client side do not seem to be available. A VNC forum discussion forum did not provide an answer (https://groups.google.com/g/tigervnc-users/c/vy-lLJ3p8lY).

Do your think that your setup could incorporate an xrandr -x, so that the VNC target does see the screen mirror flipped? For that purpose a separate display (to the left or right ...) would not be necessary. A reflection of the main display would be just as good.

For some reason my second display is always mirroring the 1st, and my display manager doesn't show a second monitor existing.
I'm setting xrandr to put the second display left of or right of, and there's a bit more desktop available on the second monitor since it's a wider resolution, but it's basically mirrored rather than an extended desktop.
Any ideas for something I can try to fix this? I'm out of ideas :/

It looks bad in both ways, horizontal or vertical. Workspace is somehow very limited. I checked the resolution with site you provided.
