How to get 2k Resolution & 577 DPI on your M9

This started as a simple method to help or interest other's. But some how it turn into a disaster by the majority of the community/admins .. I'm explaining on how to do this ONE LAST TIME for the guy( jmwils3) I was going to reply to before my thread was closed down and to all the few people who were really interested in this but couldn't receive the info since I was silenced by Tin Foil Hat People/Fanboys .. For anyone else still interested in my insightful info or want to know more of my development in linux base operating systems, Please feel free to PRIVATE MESSAGE ME. Now on to the 2k Resolution/577 DPI Method for the M9>>
Requirements
-You must be rooted
-You must pick a different launcher than stock. (For me Nova doesn't work well. I use the Dodol Launcher and then resize Icons and widgets depending on preference)
-(AND REMEMBER RESIZE ONLY AFTER YOU HAVE ACCOMPLISHED YOUR CUSTOM RESOLUTION)
Method 1
Here I will only explain the most basic method/easiest way to do it..
-Download the app called "Resolution Changer Pro" <<DISCLAIMER>> I do not condone or represent this app in anyway, NOR do I even Know that developers of this app. In fact I don't even give two flying [email protected]#KS if you use another similar app to achieve the same goal( I just found that one works with my M9) <<Plus I felt I just had to say this disclaimer for the nimrods that will say"He's getting paid for advertising dissssssss!!" LMAO
-Next change the height to 2560 and the width to 1440 and lastly dpi to 577 and then hit Enable
-At this point everything going to get weird . But don't worry it's cool Next I need you to go in the same app and touch the "Fix navigation bars" )This is because us HTC one guys have the on screen buttons(Other phone users shouldn't do this)
- After that is will fast reboot and you're all done!. Just resize Like I said from your launcher and you will be straight.
Other Methods
There are other methods done by hard code and build prompts. But I will wait till people start asking me for a more stable/clean method without all the [email protected]#HING (But the method above should suffice)
OH! AND ONE MORE THING FOR "CONFIRMATION"
-Go to the youtube app and you now have the 1440p(2k) viewing option. And watch the BIG DIfference in detail! ( I choose to watch MKBHD videos since hes one of the few that upload videos in 2k to 4k on youtube)
You can also go to antutu benchmark app for the final results as well as I did in my OP.

You do realize that you aren't changing the resolution of the screen. That's NOT POSSIBLE.
What you're actually changing is the DPI. Basically you're tricking the software into thinking your screen is higher resolution. You're NOT changing the actual resolution of the screen. Take a microscope and examine the screen. There's no difference.
You get the 1440p option in youtube because the software THINKS you have a 1440p screen. You don't. It's like watching 4k movies on a 480p TV. It's possible, yes, but stupid.

So explain to me why HTC didn't just put the worst resolution screen in the phone and just change it in the software? Why wouldn't every company do that to save money? Because it's not possible.
There are a set number of pixels on a screen. You cannot change that.
And you don't need a microscope. Just a macro lens and a good camera.

Same reason they underclock the CPU before launch(They were "Cautious"). And mind you, I never said we were changing the "PPI" in the OP. I said we were changing resolution and "DPI". BIG DIFFERENCE.... What method we are practicing here is basically changing the dimensions of the image of a 1080p display to achieve a 2k almost or the same equivalent in quality . It's true we known from mistakes in the past by doing this to dvd and upscaling them to HD can cause distort images sometimes. This s NOT the case with a "5 inch display" compared to a 42' inch Television. Hence why I also said In my OP that it will get weird after the resolution is set. But the launcher correct this issue easily simply as I stated before it's only 5 itchs we're dealing with. Maybe you should try it first before shunning it. The video playback is quite good.

Got a headache reading your posts. Thanks.
Why stop at 2k, why turn your 2k display into a 4k? Heck why not 8k?

LOL, Don't mention it .. And I suppose it would depend on hardware. And there isn't an 8k option on the youtube app that I know of as of yet. Not even a 4k option. But like I said of what "I Know" .. Maybe you know something new that I don't

Hey, changing the native resolution of the screen is physically IMPOSSIBLE. It is built into the hardware. The screen itself supports up to 1920x1080 resolution. Anything you think you're changing it to is not real. You're just making things smaller on the screen to give it a 2k effect.
That would be like buying a 1080p television and saying you can change it to 2k or 4k. Why wouldn't everyone do that then?
You should go read about the differences between hardware and software.

AGAIN WE ARE NOT CHANGING THE "PPI"!!!!! .. Seriously if people keep addressing the SAME CONCERN insanely over and over AFTER I have explain it countless times in this thread and others, then I will just lock this one up. Since my goal of getting this useful information is already given out to the community as per attended. You and everyone concern in this issue you feel you're having; Should really read INTENSELY in the difference between "PPI" & "DPI" . And then read more on "Changing the dimensions of an image"

So change your wording then. People who don't know better keep thinking that you're making the phone have a actual 2K display like the S6/M9+.
You're changing the DPI which can be done with a simple build.prop edit and has NOTHING to do with resolution.

No one is being rude. Your title (and your other post) say that you can change the resolution of the phone. All I'm saying is that that's physically impossible. I'm not attacking you at all. You probably meant change the DPI only.
Also, you kept saying that the screen looks a lot better and videos look more clear. It would be the same as watching 4k movies on a 1080p TV.
If you want to provide facts, go for it. That's the point of this forum. If you know something, you're free to share it.

So you are increasing the resolution but not the PPI here!
How is that even possible?
Changing your DPI will not increase the resolution of your screen.

My apologies, I simply took it the wrong way. And yes you can change the resolution. What you mean to say is we can not change the "Native Resolution" which I never said we were doing to begin with. Again "BIG DIFFERENCE"
And yes it looks better due to the fact of "Chroma Subsampling"

So you don't read all the "TWO" pages in this thread. And you have the nerve to be griping about an compliant/issue .. From what I'm told; XDA is suppose to almost embody of ALL the people that is going to "SEARCH" and "FIND" the "SOLUTION" to their "PROBLEM" / "CONCERN"

Just so you know the problem is starting due to the misleading title of your thread. You are in fact not increasing the screens resolution. You are downsampling in order to trick the GPU into displaying a higher resolution but the quality is simply not there.
When a display has native support for resolutions up to 1080x1920, you can use downsampling to send out a signal which tells your display to output a resolution of 1440x2560. HOWEVER, a typical display with a maximum resolution of 1080p has around 2 million pixels, while a 1440p/2k display has around 3.5 million.
Of course, downsampling does NOT increase the amount of pixels being displayed, that of course is physically IMPOSSIBLE. Your display CANNOT go beyond native display physical limitations determined by the screens ppi. All your method does is simply trick gpu to push fake 1440p resolution to your 1080p display. This cause compression to fit inside the screen. The effect it has is akin to zooming out on a lower resolution picture.
Also as other users posted, and is a 100% correct, you can change dpi through build.prop edit without all this other nonsense.

What are the default for the. M9? Did this and want to go back. It causes some issues with the camera.

Clarity/resolution

The LG V10 has a crazy crisp display. Just kidding, this is automated text so who knows if this screen is any good. So, you be the judge! A higher rating indicates that it's extremely sharp and clear, and that you cannot see pixels with your naked eye.
Then, drop a comment if you have anything to add!

I dont know if you guys and gals with good eyes notice.. But I suggest anyone looking at an LG G4 or v10 to look at and read the screens with reading glasses on.. The IPS screen clarity is unrivaled.
For my eyes, the ever so slight increase in size to the G4 makes the screen easier to read.

as if...

I think the display has excellent clarity and with 560 DPI you would be hard pressed to see imperfections. Could it be something wrong with your software configuration as hardware problems would be evident all the time ?

I'm really enjoying the clarity of the resolution, but in the last few days I've started to notice something strange. Had the V10 for almost a month now. I've noticed that every now and then, when I hit the power button while looking at the screen, it looks like an old 3D effect (seen without the glasses), around all writing and icons. It looks like red & blue outlines, sort of 1/2 & 1/2, and only for a millisecond or so. Anyone else seeing bad 80's 3D?

It's hard to understand what you are seeing.
It could be the Lock Screen's Swipe Effect or maybe the Blurred background view that happens when the phone is On and the Power button is held down to view the Shut down choices.
Check those to see if they are causes

Xperia X Performance Video stutter!

First time im posting here, I read a lot before posting about modifications to make the Heat threshold higher before the cores get unplugged, I have never modified a cellphone in my life, so I dont understand anything to much. Currently im having a problem with a Xperia X Performance I bought for 388 new from a amazon sale. Phone works perfect and I can't complain, but there's only one thing, I bought it cause of its video recording and photo capabilities, I haven't had a problem taking picture, but while recording video, no matter if it is at 30fps or 60fps, my recording stutters at random times, and after 2 minutes of recording it gives me a overheating message.
I am guessing the sutter comes from the heating itself that makes the phone go crazy, I read the max temperature on default it holds before going nuts is 47cº, and theres a mod to make it go to 56º or more before going nuts. If this is the problem then could someone help me or explain me how to modify it? Or if the video stutter ir something else I would appreciate some help! I need it to work before the 27th because im leaving a on 3 month trip and need to record a lot, bought 5 SD 64gb 90mb/s cards as they are the best for filming.
Thank you!

From what i've found, seems like rooting and unlocking a xperia X performance device is way harder than a normal device....

note going 120hz

https://www.youtube.com/watch?v=LzC_kkbFTHQ
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

...I was replying to the other post (that I quoted).
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.

So samsung Note 8 runs on 60 GHz?
And razer runs on 120 GHz

No, just Hz. And yes, 60 &120. Did you join xda just to ask this question ?

Lag when viewing 60 fps video 1080p

When recording a video in 60fps 1080p.
The preview of the video is lagging terribly, i hadn't noticed this before.
The output video is fine but the preview is about 10 fps
P20 Pro
c782
L09
110
Haven't made any major changes.

Yeah, I've just noticed it too. It's a horrible glitchy mess when recording. Tbh I'm massively disappointed in this phone. I use 60fps a lot (the kids do lots of sport) and my old S7 had none of this. The lack of AOD notifications (other than SMS and calls), the not that great battery life, the terrible Bluetooth call quality, the occasional stuttering when scrolling and the shear mad size and weight of the phone means it's going. I've had enough.

Can i just ask, are you rooted? Running any mods? Anything they may have an impact ?
I am. rooted and my wife isn't and hers is flawless, not only that but my phone is also perfect at 60fps video when it was pure stock.. I just don't like stock.
Not sure what to do but I'm about to install 131, I'm assuming it'll probably fix it.

No, it's totally stock, the stuttering nightmare that it is. Worst of all though is the Bluetooth call quality on any connection (car, earpiece, headphones). Hideous to the point of unusable. I'm having to revert to using the loudspeaker (I often use my PC while talking). It's also a flipping brick of a phone. So much heavier than it needs to be.
The only thing I can think is that it I used the PhoneClone app on initial setup to pull a lot of my apps and data from an S7 to the P20 Pro. Maybe this causes issues but I've not seen anything anywhere.
BTW, nice avatar. I'm a season ticket holder.

Ah that's a great help pal, I feel better now :good:
I'm also on 131, and was on 128, it's affecting some people, not all, my wife has the phone, doesn't happen to her.

Mine is gr8 no lagging issues from 110 to now 130
All works fine no lag

By the way this is best battery phone i have ever used.. I'am on 130 now it's impressive
I got 12 hours of heavily usage with this phone(games mainly.. Social apps .. Camera..) and wonder what i put it for charging while it's around 10%

Are you referring to the camera in 60fps?
I know that most people don't have an issue, I wanted to hear from people who do

It is due to a software problem. Cause when you lower the screen resolution to 720p. If you turn on smart resolution or the hd+ resolution the problem fades. Someone kindly point this out to Huawei. My model no EML-AL00 P20 i brought from china

Yep found this out a while ago

U need turn your phone screen resolution to maximum FHD+ after try 60 fps
