April 3, 20242 yr New 6.x based kernels for OPI 4 LTS seems to be a hit or miss for HDMI monitors. Some work, and others especially TVs dont output video at all. Images with 5.15.x kernels dont have this issue.
April 4, 20242 yr Yes, I have similar reports for both rk3328 and rk3399 devices. Looking into the kernel, effectively something has been changed upstream, but unfortunately I don't have such issues with my monitors and it becomes hard to debug
