i.MX6 video output at only 30Hz

[eug]

Hello-

I have a baremetal install on an i.MX6 SABRE and it does not work with most monitors or projectors via HDMI. Based on my investigation, it only works with monitors that can support 30Hz. Any ideas on why this is the case or what I can do to change it?

In code, I do have source/sdk/drivers/hdmi/hdmi_common.c and one of the Cases covers 1920x1080p @60Hz

Thank you!

Hi,

 I just see this https://community.nxp.com/docs/DOC-94139  so sorry about this.

Have a nice day

Rita, this was generated from an NXP contract. This was left un-addressesed and we're trying to clean this up. Direction on where to look is all we need.

Currently as best as we can tell, the entire system is hardcoded to 30Hz and is display agnostic.

We are also using the i.mx6 quad SABRE.

Thank you

The screen display is also depending on the HDMI support setting.

Hi,

Which i.mx6 product are you using?

Best Regards
