Hi Sirs

We require LVDS panel pixel clock is 65MHz.

But we only see output is 37.5MHz as below. How to set or modify it to meet 65MHz?

Thank you for your great support.

Hi Karl,
the HDMI display resolution is defined through EDID (page18 in d/s), please make sure that you had connect the UB948 with UB949. In your case, the HDMI freq. is NOT stable, it seems the HDMI source is not correct. thanks.

best regards,
Steven
