--- Comment #19 from Timo Aaltonen <tjaalton at ubuntu.com> ---
not sure, we added a workaround for this:

"Lenovo 20JEZ2ZLUS product series contains a Intel GEN9 display with
Parade DP->HDMI passive dongle, which is not being handled well in the
Linux driver or is not responding well. After some joint debug, based
on Parade's recommendation, the short term solution is not to write on
the TMDS_OE register (0x40, offset 0x20)."

apparently support for this was supposed to land late last year, but that's not
at all certain..
