Touch alignment issue - Waveshare 7 Inch

Help and Support
1

I am using the below display with my Pi 4B 1 GB model. Everything works fine except a small shift in the touch. Basically if I need to play/pause, I need to touch a few mm left almost on the previous track button. Looks like a touch calibration issue. Any help here?

@gvolt and others, Any help?

Hi @njaustin123

What is the output of:

cat /boot/config.txt
cat /boot/userconfig.txt
cat /boot/volumioconfig,txt

Have you tried to setup your screen using the plugin “Pi Screen Setup”?
If not than factory reset your device and install the plugin and perform the setup.

Haven’t tried “Pi Screen Setup”. Will try it later after you confirm.

Please factory reset the device and use the plugin.

@Wheaten , Tried Pi Screen Setup. It seems working even without factory reset. Now touch response is fine. Thanks a lot.
