Maybe try commenting “hdmi_timings” in “/boot/userconfig.txt” and adding
hdmi_cvt=1080 1920 60
No liability assumed 
Hi! I have a similar issu: RPi 4 and 5.5 Amoled touch display, but I can’t get the screensaver working. The display always shows the Volumino screen - even if the ‘Monitor is Off’ (after I run the xset -display :0 q comand)…
Any further hints?
Please add “hdmi_blanking=1” to /boot/userconfig.txt

Thanks! It works!
hi, what is the best way to rotate the touch on this screen ? Plugin rotates the picture but not the touch. I’m on 3.175 version.
I think touch rotation should work. What rotation do you try to achieve?
After setting the rotation from the plugin’s config page please post the results of
cat /boot/config.txt
cat /boot/userconfig.txt
and
cat /etc/X11/xorg.conf.d/95-touch_display-plugin.conf

Looks ok so far. Did you install other display related software or plugins?

I assume “40-libinput.conf” has not been modified. If you set rotation to 180 deg. is touch rotated properly / wrongly / not at all?
hi,
180 rotates by 180, touch doesn’t work at all, I’ll do a clean install over weekend
Just to clarify: Do you mean, not at 180 deg. or not at all?
Yes indeed, not at all
Ok, that’s an important clarification. My understanding from post #30 was that touch works but does not rotate accordingly to the display.
Sorry for aksing the obvious, but do you have the display also connected by USB (connector 4 not 3 on this picture) to the Pi?
If so, does an input device show up?
ls -al /dev/input/event*
yes indeed, USB cable connected to correct port on the screen. I tried with multiple USB cables making sure that they have all the pins (not just the charging ones)
ls -al /dev/input/event* returned:
ls: cannot access ‘/dev/input/event*’: No such file or directory
Then the touch device has not been detected 
Maybe post the result of
cat /var/log/Xorg.0.log
or if you are starting from scratch anyway, wait to see if that will “solve” the issue.
I haven’t yet

Module “libinput” does not get loaded, which is why touch does not work. Maybe try uninstalling the Touch Display plugin, enable “Plugins Test Mode” on the “dev” page and install version 3.3.2 of the plugin.
