Hi Werner,
Based on the discussion with our hw team, changing the LNn_CFG4 to all 0 is the solution for this issue.
I will prepare a change to this.
Thanks,
Hai

There are certain modes (generally for HDMI/DVI) where the refresh rate isn't an integer. It can be something like 59.94 Hz, or 60.04Hz. The above calculation may not work well with such modes.

We have platforms where the DSI output is connected to HDMI bridge chips. So the issue I mentioned holds true for msm/dsi too.
That makes sense, the non-integer vrefresh rates completely slipped my mind.
Thanks!
