Is it possible to limit HDMI2.1 to 2.0?

Hi NV,
cause of some reason,
we would like to limit HDMI2.1 to HDMI2.0,
is it possible to achieve by SW modification?
thanks.

Hi,

Is the development already starting or you are just checking and doing evaluation?

Hi Wayne,
we are checking and doing evaluation,
but very likely need to do that cause of HW limitation,
thanks.

Hi,

We have below questions here to understand the problem.

  1. By limiting to HDMI 2.0, is it because you don’t want HDMI 2.1 TMDS or HDMI 2.1 FRL?
  2. What exactly is the limitation from your side to limit to HDMI 2.0 ? Is it wrt your platform or sinks(monitors) you use?

Hi Wayne,
the HDMI connector and HDMI re-timer on our carrier board just support HDMI 2.0,
I think HDMI 2.1 TMDS/FLR doesn’t support either,
thanks.

Hi~Wayne,
Since our HDMI re-timer only supports 6Gbps per channel of TMDS signal, Can we just disable HDMI 2.1 FRL function on Jetson Orin NX/Nano module??

Thx

Hi~Wayne,
Sorry to bother you. Is there any update?

Thx

Hi Ken,

This is still under internal discussion.
