Question Pixel 6 (Pro) Variable Refresh Rate

[Opensystem]

Hey guys, looking for confirmation. I recently started exploring this phone's VRR to see if I could find a way to force max refresh of 90hz on the pro to try and save battery. Ran into trouble and found this video showing the phone only goes from 60-120hz:

I've heard arguments against being able to see the refresh rate with the developer options tool, as refresh rates of LPTO displays happen at lower (hardware) level than the "show refresh rate" tool (software) can view.

Many VRR displays use profiles rather than true "seemless" switching, ie: 1hz, 10hz, 11hz, 24hz, 30hz, 40hz, 60hz, 120hz.

Does anyone have the necessary expertise to tell me what's going on here? Do our Pixel 6/Pro displays have two refresh profiles, 60hz and 120hz, and that's it? Or is this a failure of the methodology being used in the above video's test? Further, is this a hardware limitation, or something that can be fixed via a software update in the future?

Thanks to anyone with some insight

*Edit* Here's a pic of the website "smartprix" claiming the P6P is variable down to 10hz

Here's another troubling post about the display on this thing, if anyone is interested. I'm hoping we can get some of these things addressed in updates, because I really love this phone. I just want to find a way to make the battery last a bit longer..

Are these issues that perhaps custom kernels may also address? Sorry if any of these are obvious questions, I just plan on keeping this phone a long time and hate seeing these head-scratching issues. Thanks

He also mentions in that thread that this is pretty much unfixable. I wouldn't bet on custom kernels etc being able to fix this.

It is fixable (in theory).

The hardware supports a variable refresh rate from 10-120 Hz, so in theory that can be used "fully". Meaning 10, 30, 60, 24, 90, whatever.

BUT - Google locks it down. As of now, we do not know why, or how.

Maybe someone will find/make a fix/a mod one day, maybe Google will do it.

Right now we do not have a fix, and don't know more. Not much more to say.

So, would it be better to force 120 Hz in developer options?

I don't see how, it would just cost more battery. The phone ramps up to 120hz fine, it's lower frequencies that are the issue. Which leads to yet another thing that's compounding battery problems

Is it possible to get different control with a custom ROM?

Interested to know if you've found any updates on this in the almost 2 years since you asked. Setting the max refresh rate to 90Hz would be cool!
