General discussion • Re: How to use Pi5 with an HDMI KVM?

Thanks. I'm trying to use 1920x1080@60D but that produces too high a dot clock. I.e. if I look at /var/log/Xorg.0.log I see a dot clock of about 172 MHz, which my monitor cannot handle.

According to the monitor's edid, it wants a dot clock of 148.50 MHz for 1920x1080 mode.

I'm looking at the modedb.rst documentation in the kernel source code, and I don't see a way to set the dot clock. I've played around with some of the optional flags (M and R) but so far haven't gotten it working.

I'll keep experimenting, but if anyone knows how to set the dot clock I'd love to hear about it.
