7" Zoll Display

Hello, I connected a 7" display with HDMI and USB cable to a Rasperry 4. The display is plug and play, the HDMI cable is recognized but there is no image output. Touch Display Plugin 3.3.5 is installed.

Is the display connected to HDMI 0 of the Pi 4?

Did you enable the Touch Display plugin?

Also please provide the manufacturer and the exact model name of the display.

I connected the display to HDMI 0+1.
With both HDMI outputs no signal.
Touch Display Plugin enabled.
Manufacturer: CUQI
Model: JRP7002
The display is ok tested it on my computer.

Do you have a link to the specs of the display?

Seems this is the link:


Add to userconfig.txt

hdmi_cvt 1024 600 60 6 0 0 0

Thank you for your help.
Since I am a beginner, I still have a question.
How do the data in userconfig.txt get without building the SD card.

If @Dirk1’s display should be the goodtft 7inch HDMI Display-C I would suggest to omit adding display_rotate=0 to “/boot/userconfig.txt” and let the Touch Display plugin handle rotation.

open a SSH session:
SSH - Volumio Documentation.

nano /boot/userconfig.txt

and add the lines


Connect to Volumio via SSH, then open “/boot/userconfig.txt” with nano (editor):

nano /boot/userconfig.txt

Do your modifications and save the file hit Ctrl+x, y and Enter.

Thanks for your help, I have to go to work when I am back home weekly I can get back
Greetings Dirk

the image is there now, but smaller than the viewable screen and distorted.
I tried to adapt the image via the touch display plugin without success.
The touch function input via screen does not work since.

7’’ standard display, 1024 × 600 resolution.
◇ Capacitive touch screen with camera and microphone.
◇ Supports standard HDMI interface input, compatible with and can be directly inserted with
Raspberry Pi 4B 3B+ 3B 2B.

in port 1 from the back left you have your touch
in port 2 from the back left you have your power
in port 3 from the back left you have your hdmi.

this should be good
