7inch HDMI Display-H Rotation

Hi everyone!

I just got my hands on a 7-inch HDMI Display and even after following the configuration from the seller, I can’t get it working as I want.

I’m using this guide since this is the closest model that I’ve found (I have the Rev1.1 and the doc is for the 0.3).

So I’ve edited /boot/firmware/config.txt as follow:

changed dtoverlay=vc4-kms-v3d to dtoverlay=vc4-fkms-v3d

and then appending the following:

hdmi_cvt=1024 600 60 6 0 0 0

I’ve tested both hdmi_cvt 1024 600 60 6 0 0 0 and hdmi_cvt=1024 600 60 6 0 0 0 and weirdly enough it doesn’t change anything but I thing this is a typo from the doc…

So with this config the screen is working, clipper screen is running and touch capacity is available.

However now if I try to rotate the screen with the display_rotate nothing change.

The only way I’ve found to rotate the boot screen of the Pi is to comment out the dtoverlay=vc4-fkms-v3d or dtoverlay=vc4-kms-v3d but then Klipper Screen doesn’t start.

Can someone help me to figure this one out?
I’m using a Pi 3B+ with bookworm Lite 64bit
