Nexus 5 has a 120hz touch controller - Nexus 5 General

In case you were wondering.
Source: http://www.theglobeandmail.com/globe-investor/news-sources/?mid=prnews.20131120.SF19611

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...

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

*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!

Movie Frame rate

been noticing that when I play a movie either using the You Tube, Netflix, or Google play app the movies seem to play in 30 fps instead of the standard 24 fps.
It looks like the way Soap Operas are shown on TV.
Has anyone else noticed this?
Can this be changed?
Thanks

Does your tv have frame rate processing (stupidly marketed as interpolation), i.e., an LCD at 120 or 240 Hz, that you haven't turned down?
I saw what you're describing on an unadjusted Samsung SmartTV, but not on mine, it's dialed back.

If it's a Samsung, look for Auto Motion Plus under Picture Options.
You can dial back the effect or turn it off altogether.
Also look around for an Edge Enhancement setting, maybe under Advanced Options or Picture Options - having that on can contribute to the effect as well.
Those are set independently for each input.
Mileage varies for other brands but it's the same deal.
The correct setting?
What works for you.
I like to dial up just a little bit of that, not soap opera look, just less jumpy and smoother looking to me.
Some people dig the soap opera look. Some people dig none of it.

Have you ever seen high frame rate video - typical of how a soap opera looks (stark, sharp edges to everything)?
On the LCD TVs with high refresh rates (240 Hz, etc - and LCDs don't refresh, they're not decaying-output phosphor displays, they update), they have the ability to take a normal movie, process the picture to remove motion blurring and attack telecine artifacts (judder) -
And if you really wind the feature to max, you can get a normal, soft movie looking like a daytime soap opera.
The term was coined among HDTV users when the feature first appeared some years ago.
(Sorry for the run-on sentence but not sorry enough to fix it lol.)

PS - it's marketed as interpolation - i.e. 30 frames per second becoming 240 frames per second.
It's great marketing but total hogwash because the algorithm doesn't work that way.

Blurry Vision? (QHD Display)

EDIT: Is it just me or is this normal for QHD or display of this size to exhibit scrolling blur. Whilst browsing using chrome or XDA app anytime I scroll I find that nothing is crisp it seems to be blurry until the scrolling comes to a stop. With this type of quality display I expected better, or am I just being too picky? Anyone else notice this or have the same issue.
The display is QHD (2k) nor UHD (4k). Also there is no scrolling blur for me when I use chrome or XDA. Did you change anything in the phone?

My bad, lol... I haven't changed a thing. Adaptive brightness set at default ambient display switched on. No other changes, not rooted ATM, just stock??
I just got one with project Fi and coming from an HTC M8 I see the scroll blur. Makes me wonder about OLED TVs.
I've never seen this issue. Are you sure it is a display artifact and not some kind of rendering / performance improvement for scrolling in stock?
I'm using a custom rom.
What you could do is try and record your screen using an app like this...https://play.google.com/store/apps/details?id=org.mistygames.screenrecord. If the issue doesnt appear on the video but does appear to your eyes, then it is the screen. If it is on the video, it is your software.
Like I said, never seen it myself, though that doesnt mean its not there,

All TV technologies, when new are inferior to previous technologies that they replaced. The previous technology has always had time to develop. For instance, LCD TVs are pretty good now, but my 2006 and also 2009 LCD TV's have terrible motion "jerk". I still use that 2009 TV.
OLED have only been out what? 2 years on TVs? Yeah I wouldn't necessarily buy a 2 year old model.
If this issue is a screen issue, it's worth noting that the screen on the N6 is old OLED technology. It is not up to date, like the Samsung Note 4.

note going 120hz

just came out today,? is will their be a mod to put note 8 120hz or im i going to hear the magic words ...no its hardware thing?
Um ... why , 2k screen at a 120hz would take some power. Plus with small size really wouldn't be worth it. High fps really only matters in shooters on pc. On a phone there are too many weak links to make it good for games that would call for 120hz..

Hz (refresh) is not the same as fps (framerate)...
And higher refresh rate actually makes everything smoother, including simple animations, etc. For example, I have a three monitor setup (2 x 60hz, 1 x 144hz), and you can easily see the difference just by moving the mouse cursor. Much smoother and easier on the eyes.
Razer includes a 4000mah battery...if Samsung bumps up the Note's battery capacity again in the future (and/or introduces further OS optimization for increased efficiency) then it could mitigate any additional draw in power. Personally, I think a Note 9 or 10 with faster refresh would be sweet

Yes it can be done, the Razer just did it. Not likely on the Note 8 though, but can't really say for sure. I do know that the refresh rates of some monitors can be overclocked, but it only works up to a certain point (much like ram or processors). So even if it were possible to increase refresh on the Note 8, I don't think it would be anywhere the Razer's 120hz. Happy to be corrected if I'm wrong though.

Just found this article which explains a lot:
https://www.androidauthority.com/120hz-displays-the-future-or-just-a-gimmick-782717/
Sounds like the refresh rate on the Note 8 could theoretically be increased through software alone, but that it would likely introduce issues such as screen tearing, etc. In contrast, the Razer's panel (for example) has hardware technology to reduce or eliminate these types of artifacts. So I'd say yes it could techically be done on the Note 8 to some degree, but even then the results wouldn't be great. Better to have the hardware that makes it work right and delivers the desired/expected visual experience.
OLED is not able to do those high refresh rates yet.... Its hardware
Even if you got it to work it would absolutely kill the battery and if/any games even are optimized for 120 hz is another story.

You can see the difference if you have the video/game that uses it otherwise it's number theater . I would venture most folks couldn't tell between 60 and 144 unless it was in action. 24 to 60 yes, but beyond 60 is splitting hairs. Also on the small form factor of a phone, with the control latency of a phone not sure tour getting bang for buck . I am aware that Hz and fps are different ,just as I am aware that using different refresh rates in a triple monitor set up is just asking for problems as well. To me it's just the same as THX speakers on a phone or Dolby Atmos on a phone, yes they're there but it's more like a gimmick because of the small form factor. I am also biased towards pc gaming , and could not imagine playing any serious shooter on a phone, just like I couldn't do it on a console either(but at least consoles have the horsepower now).
My biggest fear is this catches on and Samsung ditches it's Amoled displays for LCD just to get the specs for the next phone.

No as I said you can see the difference just moving a mouse (or watching movies, etc). Also, no issues at all in a triple monitor setup with different refresh rates, so long as you know what you're doing. Obviously if you try and play a game on 3 monitors at once with different rates then you're asking for trouble lol. Anyways, moot point now as OP's question has been answered.
Animation in android
Can the animations and UI in android currently even run at 120? Are they not rendered at or around 60fps?

I wouldn't put too much credit in this article. They seem to be sort of talking out of their asses on this.
Adaptive display technologies reduce screen tearing yes, but their main benefit is the reduction of resources. Allow me to explain.
Your free to correct me if I'm wrong but this is my full understanding.
When a screen displays an image it has to get told to display an image. However, it's not quite as simple as the CPU saying, please display an image.
The screen will continue to display an image until it's told to Change to a new one (think of when your PC freezes. This is why the image can sometimes freeze. The display adapter has stopped sending new images to the monitor).
So what happens when your computer is creating a new image, 1000x a second? Well, it would tell the display to "display" 1000 images in a single second, even though it's only capable of let's say 60 (this is where 60hzcomes from) this creates the tearing effect. To combat this there are controls we can use, Such as vertical sync, where we can just Pull an image from that 1000 image pool when we want to display a new image. For example, your phone might tell android, since it is running at 60hz to just pull a new image from that pool once every second. We could also limit the software to only create a new image once every second as well to combat this. The problem with these is they require CPU cycles. And they have an impact on the memory, with the frame buffer holding that 1000 count image pool. Ideally went want the CPU to only worry about creating an image when we 'want' one. So that it can move on to the next process in it's Queue.
With adaptive display technology, we can 'sync' these two numbers without creating a significant performance impact, and because we have synced them the overall smooth transitions require less motion smoothing, or blur effects that alot of movies might use to help create that clean look (This magic is why movies at 24fps look fluid). When it comes to Android, 120hz vs 60hz would most definitely be noticeable, so long as UI transitions and the OS itself had animations that could display 120 different frames. Currently I think that it does not. Also, let's be honest, until the hardware starts supporting it, android won't support it. We are starting to see that support now, in the Razer phone and in some Sony phones.
I am unsure of the currently refresh limits of OLED. I do know however that OLEDs response time is faster than that of LCD. Response time doesn't directly effect refresh rate, That would be the job of the display controller, or whatever that strip is called haha. Response time is important though as it'll determine the quality of the images being displayed at higher refresh rates. Which would be the significant factor in whether you would want your display running at 120hz or simply 60hz
Also... Before anyone chimes in, with "you can't see more than 60 frames per second" your wrong. Don't bother. Sorry, but you've done zero research.

Screen refresh rate

Hey guys, first time poster here.
Got my P20 pro about 5 days ago and one major thing I'm noticing is I can't look at the phone for too long because it really starts to hurt my eyes
I was wondering it might be tied to the refresh rate. Does anyone know what it is for the phone?
Logging into youtube to watch a video at 1080p does not state '60fps' on this phone, but does on others.
Does this phone have a sub-60hz display?

It's not the refresh rate of the screen. It's probably because you have such a wallpaper that in the lowest brightness setting emits an uncomfortable blue light radiation. The refresh of the screen is just fine. As for YouTube, it supports 60fps if the source video provides it. I've noticed the same thing in the watercolour theme when the brightness settings where in the lowest point inside a very dark room. Apart from that situation, my screen is super confi in every light situations. (and when i changed me theme for a darker one, even that problem was solved)

Ahh I see. What a weird behaviour.
It's worth noting though that it's uncomfortable to look at on all brightness levels and with the use of eye comfort mode.
I'm starting to think it's just my eyes.
But on my many other devices I don't get the same problem
If your internet is kinda slow, youtube could remove the 60fps option for you.v
For me, I only noticed the irritating wave length emission only at the lowest brightness setting in watercolour wallpaper. It may have something to do with the specific colour and the lowest possible brightness setting. I must note, that it has a very low brightness setting as a phone. That's a good thing at night. My oneplus didn't go as dark as p20.

Ever since I got my phone it was able to playback 60fps YouTube videos. My firmware is currently (.130) Keep in mind it was still able to playback 60fps videos with older firmware.
You can always try going to www.testufo.com and see what refresh rate is this playing in the test.
With my Razer it shows as 120Hz but you should see 60Hz showing up.
With my Asus tablet P01MA it shows up as 30Hz.
Of course it's 60hz

This exact same thing happened to me with my Mate 10 Pro. It really hurts my eyes in such a bad way that I have blurry vision after looking at it, and some weird head aches. There is something wrong with these phones. I just ordered the Mate 20 pro but I think I will send it back. This needs more investigation.
