180hz touchscreen - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

Does the 180Hz touchscreen work or is it just advertising ****?
Now it definitely does not work at 180, but perhaps it is possible to change the frequency.

Excuse me what the fok

wat

,???????

It works even on 240 hz with vsync and 8k

In their advertising company, they said that the touchscreen has a refresh rate of 180 hz, but in fact there is no information other than in the advertisement about it.
Also in comparison with my iPad (there the touchscreen is 120 hz) on the phone input delay is much higher.

its touch sampling rate, something else. Next time you can use google

Exactly, he says it's the touch "sampling rate" not the "touchscreen refresh rate"

it's same thing, the number of sensor refreshes per second (180 hz = 180 updates/second)

Touch should be measure at ms or something?

Who cares about that? Lol

the touch sensor and the screen itself are 2 different things

Touch sampling rate is the frequency at which the touchscreen tracks the movement of your finger.
Display refresh rate is the frequency at which your display updates with new images (frames) each second.

Can we increase our frame buffer rate past the 60 limitation? Other devices have!

UPDATE!!!
links to what i am talking about. Want to change the frame buffer rate.

*What Refresh Rate Means*
With the introduction of television display technologies, such LCD, Plasma, and DLP, and also Blu-ray Disc and HD-DVD, another factor has entered into play that affects how frames of video content are displayed on a screen: Refresh Rate. Refresh rate represents how many times the actual Television screen image is completely reconstructed every second. The idea is that the more times the screen is "refreshed" every second, the smoother the image is in terms of motion rendering and flicker reduction.
In other words, the image looks better the faster the screen can refresh itself. Refresh rates of televisions and other types of video displayed are measured in "hz" (Hertz). For example: A Television with a 60hz refresh rate represents complete reconstruction of the screen image 60 times every second. As a result, this also means that each video frame (in a 30 frame per second signal) is repeated twice every 60th of a second. By looking at the math, one can easily figure out how other frames rates related to other refresh rates.
The important thing to take into consideration is how the increase in Refresh Rate improves, or doesn't improve, the perceived screen image quality for you, the consumer. Let your own eyes be your guide as you comparison shop for your next television.
Is it possible to jump our frame buffer rate up past its current 60 limitation?
I will look for some links, but i know other devices (gtab?) have jumped from 51 to 79. This will make all video and games blow our mind!

Does we have this limit ? And if we have it will not affect any thing the human eye can't see more than 60 fps and the tab screen is only 68 fps so the 60fps limitation will not affect us

Nexus 5 has a 120hz touch controller

In case you were wondering.

surly it not clocked at 120hz but it is a very impressive chip
Does that mean that the Nexus 5 theoretically could support a 3D display? or am I remembering the hz?

Short answer: No
Long answer: Nooooooooooo
You're mixing the things up. The hardware in the Nexus definitely can't support a 3D screen. This was just relating to the touch screen sensitivity, and how quickly it tracks your finger. I've only skim read the article, but it seems to be saying that the hardware can track your finger movements at 120 Hz.

Alrighty, thanks for clearing that up. Was just curious, cause I think 3D TVs also run at the same frequency.

It's the same number, but they refer to completely different, and unrelated things.
The touch controller is the digitizer for the screen not the screen refresh rate. 3d TVs refresh the screen 120 time a second (more or less depending on model) this allows two separate image to be displayed at 60hz each. The digitizer has nothing to do with drawing on the screen but with sensing when you're finger touches the screen. They are two different elements generally glued together to make the screen you see

3D TV refresh rates come in other frequencies than 120Hz. In fact, non 3D TV's do as well, since Hz (when it comes to screens) basically means refresh rate. So a TV with 60Hz refreshes 60 times a second, a TV with 120Hz will refresh 120 times a second.
In this scenario, the touch screen in the Nexus 5 refreshes 120 times a second.

Its LGs update to the LCD screen, just like a TV. 120Hz refresh rate on the screen. Better pixel control. I have two TVs at home, one is 60Hz and the other is 120Hz. The 120Hz will obviously look better on-screen. Plasma TVs have higher refresh rates if I'm not mistaken 800+Hz or so

I remember it being 600Hz for Plasmas usually
In short we can have a very smooth UI.. I have 100hz LCD TV by LG and I can say its called true motion. The motion is like 60FPS video..

Touch Sensitivity is great in this
joshuaauger said:
Wow... you're all missing the point.
1. 60Hz vs 120Hz vs 240Hz Televisions are talking about refresh rate of the display meaning how many images it is displaying.
2. This article is not talking about displays but digitizers
3. The digitizer in this phone supports higher refresh rate i.e. 120Hz which means for faster touch response, and fullHD digitizer support for the full phone resolution over the digitizer.
TLDR; Phone Digitizer 120Hz is NOT the same as a TV's LCD 120Hz

I think we've already established that in all previous posts... Anyway, back to the topic, 120hz TV refresh rate has nothing to do with touch screen sensitivity...

Realme x2 pro 120hz?

guys, someone might be able to make a mod like overclocking the screen to 120Hz, forgive me if anyone decides it's stupid!)):скрещенные пальцы:
I dont know the details but isnt refresh rate a hardware thing?
Its a Display thing... 120hz will be possible if the Phone Supports it

Yeah. What I meant to say is realme x2 pro has 90hz screen so it cant be increased to 120 hz because it doesnt have the hardware to support it.

Well in theory the screen may support 120hz. But more likely doesn't. We cannot really know without an app that can push that on low level.

I think it could be possible, like Xiaomi mi 9t pro have a 81 Hz mod and it display it's 60hz
I wish someone do it <3
I also really wanted someone to make a 120Hz screen, but so far this is only a dream, but who knows maybe !!

Are google maps and whatsapp still locked to 60 hz?

Google blocked some apps from being displayed at 90 hz, do you happen to know if that is still the case with google maps (an app that is supper janky and would be benefit greatly being displayed at 90 hz) and whatsapp?

You can turn on to see the refresh rate on the top left corner in Developer Options. WhatsApp is 90 FPS and Google Maps is still 60.
