All,
I was pretty curious to try the new screen tech since the launch event, today i got the device, enabled frame rate monitor on developer settings to see the LTPO in action, contrary to what they said on launch event the screen switches back and forth only between 60 and 120hz , 120hz during scrolling , 60hz when the screen is static without any input. It doesn't go all the way as low as 11hz
Wondering is this the right way of implementation , members please share your findings or information related to LTPO here to discuss upon

read them as soon as andrei published it, would love to see his deep dive into the new panel in s21 and see what benefits it brings to the equation

Ah fair enough, he's comparisons of the two models are always worth reading! I did find the bit I was referring to if that helps. Basically the OS can't recognise the lower refresh rate but they are there.
'One problem (from our perspective) with this LFD mechanism is that it is seemingly completely transparent to user-space, so there’s no good way to verify that it’s active or working - the OS simply states that you’re either in the 120Hz or 60Hz VRR modes, however with LFD on top the actual refresh rate can be different. One way to verify this externally is simply to measure the end-result that the new panel technology is meant to bring to the user: lower power consumption. It’s also here that we encounter some of the quirks in Samsung’s implementation.'
Will be interesting to see if the adaptive rate works in lower light unlike the note!

That's the crux, whether it works or not we are limited to either 60 or 120hz on os level. Hope there is a way where this can be monitored more precisely via some workaround
This app seems to report (and limit) refresh rates other than 60 and 120hz, but I don't know how if it's not exposed by the OS.

Those refresh rates (e.g. 48hz and 96hz on Note 20 ultra) are actually exposed on OS level. If my understanding is right on the way that current android system works, S21 ultra implementation is probably the same to note 20 ultra with the addition of10hz as the lowest in the predefined set of refresh rates.
Hi
Is it possible to disable the dynamic refresh rate? I want 120HZ all the time
Also, is it possible to underclock the screen to 90hz , for more battery?
Thanks!
?? With Stock Miui 12 you can chose between 120Hz and 60Hz, no dynamic refresh rate.

Lock the screen refresh rate to 90HZ/120HZ

+1 i agree, there a lot of people said things do not know
I love this phone, but there is one huge annoyance, there doesn't seem to be a way to make the screen actually run at a sustained framerate.
I have it set to 144hz in the menu, but it routinely drops to 60fps or 120fps depending on the app
This normally isn't a big problem, except nova launcher only runs at 60fps and so scrolling the app drawer is incredibly bad.
Pokemon Go also only runs at 60fps...and since the game operates at 1/2 vsyn, the effective fps is only 30, which is atrocious compared to the 72fps it runs at on the ROG6
Don't confuse Screen Refresh Rate and Frames Per Second. Totally different things.

I mean... Not really
Obviously the screen always runs at a refresh rate of 144hz because it isn't a VRR display(as far as I know that doesn't exist on phones)
So what you are changing in settings is always the frame rate that the phone is rendering at.
Your phone should ALWAYS be rendering at the frame rate you select in the settings menu... But this phone doesn't seem to do that, and it's annoying because it makes the usage experience worse than every other phone I have

Most of the reviews I've read/watched confirm what you've said. When you set 144hz, it runs that way in the default launcher and all the menus, but when you open certain apps, if they don't support 144hz natively then they just don't run at 144hz. The reviews seem to indicate that the developers of said apps need to enable support for 144hz.
So I was poking around the settings, and entered developer mode. There's an option to force the screen to stay at 144hz at ALL TIMES. It's called LOCK REFRESH RATE. I was able to confirm this works because there is also an option to SHOW REFRESH RATE which displays the screen refresh rate in the upper corner of the display. Before I locked the refresh rate, I used the show refresh rate function to view the refresh rate using different apps. In the phone menus, and app drawer, and google feed, etc the phone would remain at 144hz. But when opening some apps like Chrome for example, the refresh rate would drop to 120hz, etc. However, when I LOCKED the refresh rate in the dev options, the screen refresh rate stayed at 144hz in EVERY app and scenario I was in. It does state that this will drain your battery more rapidly when selecting to lock the refresh rate in the developer options. FYI
Hello, to the point. I want to lower my resolution to help snapdragon 732G, for better performance. I have 120Hz display, after wm size and dpi change, will affect my refresh rate? I want to set 720p
Default resolution is 1080.2400.
I want to lower my resolution for better performance, using ADB. Default resolution is 1080.2400, im thinking for a 720. My question, refresh rate will be affected? Will get 120Hz after my changes?
.... Why not simply trying it?
Because i dont wanna brick another phone
Hi guys, it's possible put the Refresh rate always 120HZ? i think that LTPO refresh rate it's great, but i want always 120HZ, I can't found it, I've tryed to search on Display option and Development options
Many thx gyus
sorry, Oppo
I very much doubt you can, at least not without root and third party controls, which are ill-advised.
When I get my device later this week I will look into it as part of my review.
You don't need 120hz to display a static image, text etc say checking your emails - it is just going to destroy your battery life - dynamic refresh rates are the best way, so long as the firmware handling the adjustment works as intended.
