How come refresh rate switching is without a short stutter on my phone?

[thekingofmonks]

The phone in question is a Redmi Note 10 5G, and honestly, I have doubts that it actually switches from 90 to 60Hz.

Unlike a PC display, it does not stutter nor turn black for a moment, and it feels just as if the UI was simply limited to 60 fps rather than a display running at 60Hz. I'm only speaking from experience here.

Unless, of course, it is just an impression, and the reason why it doesn't stutter at all is because it only tunes down the display clocks and doesn't load a resolution profile.

All of this is very confusing. What do you people think?

It doesn't black out because the SoC drives the display directly, there isn't a whole bunch of things in the chain that need to change modes/resynchronise to the new one like with HDMI etc. 

Variable refresh rate on monitors also doesn't cause blackouts.

I think the problem is more with your monitor than ur phone. Imagine if the screen turned black every time you stop scrolling

I'm not sure what you're referring to. My laptop's display works fine, just like any other monitor.

You just said it goes black while switching refresh rates, it shouldn’t do that.

He was talking of changing resolution/video mode on a PC.

Oh i see. 

The difference is the desync between the gpu and display on a pc, vs on a phone
