Is there any IMG file to Overclock the display to 75hz for RN9 Pro
it's simply not possible because the screen on this phone only supports 60Hz, you can't make it any higher
@akramhadji how do you know ?
can you overclock your pc monitor from 60 Hz to 120 Hz? no
same thing with phones, it's a hardware limitation, you can't improve it by flashing a file.
@akramhadji , please don't give input on things you clearly have no idea on , you create noise for those searching for information .maybe it makes u feel good to have thanks ,but try to curb it aite .

it seems that you're the one who has no idea what he's talking about :/ there's no such thing as display overclocking on phones...
You cant overclock displays, you can however fool it into thinking its running at a higher rate. But it wont change anything other than displaying a higher number in test apps.
Many displays can actually be overclocked and run fine at actual higher refresh rate depending on manufacturer and hardware. That overclocking also has its limitations. Some 60hz panels run fine at 75 or maybe 80+ hz, some causes pixel skipping if overclocked and some simply don't go past 60-65hz.. Same limitations exists on phones, their display is underclocked so hardware don't go on full load and damage anything. Similar reason why note 9 pro comes with 33w charger but actually supports 30w
@akramhadji ignorance and arrogance ,keep it up .many of your kind in this world ,I won't waste anymore time .beyond savable
well, if we look at other phones :
the realme 6 : 6.6 inch 20:9, 2400 x 1080 pixel 399 PPI, capacitive, IPS, Corning Gorilla Glass 5, glossy: yes, 90 Hz
the redmi 9 : 6.67 inch 20:9, 2400 x 1080 pixel 395 PPI, capacitive, IPS, Corning Gorilla Glass 5, FHD+, glossy: yes, 60 Hz
so they changed the display, might point out to the redmi display choice being only 60hz capable.
What happens if you increase display refresh rate, well you have increase GPU usage, and depending on the type of connection between the SOC and the LCD you can have increase compression in the bus. So its a trade, do you want that?

Bro we can overclock our monitor
Since no one bothered to come to my thread, I'll just say it here, the Redmi Note 9 Pro 5G has the same display as the phone we are talking about here but it has 120hz. Oh wait, MI 10T Lite and Poco X3 also have the same display that support higher refresh rate, so it is definitely software capped. (Can't verify part numbers rn tho) and PC monitors can be overclocked anyone who says otherwise definitely doesn't know what they are talking about

Hi guys!For the last few days(that I have my Hero rooted that is) I'm using VillainRom 10 as my everyday ROM and have tried some others.Anyway,that's not the point!
Being one of the lucky ones whose Hero can happily overclock to 768 I came to use RaduG's extremekernel and ben39's no-bfs no-whining kernel.With the second,while configuring OverclockWidget I saw that it gives a 848MHz option with auto-detect frequencies.Is it possible?I'm not asking about stable daily use,but even for some minutes for benchmarking?Has anyone achieved it?Without making their phone catch on fire that is!
And secondly,why are we all using linux 2.6.29(for total newbies I mean the kernel) while there is 2.6.32-33-34?Can't a newer kernel be compiled for use with the Hero?Newer kernels would provide native ext4 support and would probably prove to be better overall.
Oh,forgot one more!I am currently running on minimum 176MHz-maximum 749MHz(after I got a couple reboots with 768 I abandoned 19MHz for stability) with screen on and minimum 123MHz-maximum 384MHz with screen off.Should I give it a higher minimum frequency?Sometimes it lags when waking up,the screen turns on but shows nothing but black and turns off again or it turns on and everything is distorted,colors are completely distorted,background is upside down and some other unnormal things,but everything is alright when turning the screen off and back on again.Does it have to do anything with the frequencies I am using?I am running on VillainRom 10.3.
Now I have set the minimums to 160 and 190 MHz to see what happens!
Thanks in advance!
About the high MHz... I have done it with over 800 but don't max it out at 848 or your phone will freeze but anything below works And that screen **** I've also had and it has something to do with the high MHz (don't know why) but it helped me to set the MHz lower when the phone sleeps in SetCPU And at last about the kernel... It runs on the old one on Android 2.1 but in 2.2 it will be upgraded to ....33 or ....32 don't remember which...

Thanks for your reply C0mpu13rFr34k!
I know Eclair is running on the old kernel.I just would like to know if it is possible to compile a newer kernel for it.
As for the frequencies...Are my settings alright?Some too high or too low?The way I see it there is a big gap between maximum and minimum frequencies when screen on which results on the CPU working at low frequencies most of the time,thus sacrificing performance.But it helps with battery life and presumably this and the screen-off underclocking reduce the overall damage caused to the CPU by the overclocking,which is said to reduce the CPU's total lifetime by 50% or more,depending on how much you overclock it.Working at 749 I sometimes get a nice 43 degrees Celsius while charging,but that's only when charging.Average temperatures are 30 for standby and 37 with screen on(average,can be lower or higher).
And one more question.At 800+ how hot does it get?Will it be stable for some minutes to do some basic benchmarking or nah..?
Thanks!

If your phone is stable your settings are just fine even though your phone might have problems waking up if the low freq is under 246MHz (something like that) Also if you want better performance you might want to test some other freqs and then benchmark... Sometimes it makes a BIG difference if your phone is running at 691MHz or 710MHz For me my phone works like **** if it runs at 749MHz but it works like a dream at 729MHz (I think the difference was 0.5-0.8MFLOPS) Im also pretty sure your temp is fine (OC shouldn't make your phone that much hotter since the voltages in all ROMs are adjustet). If you should compile a newer kernel you would first of all need a .32 (.33?) from HTC because of hardware capabilities and im sure there's is A LOT more things devs need to compile such a kernel but i don't know to much about kernels I don't really know that much about 800+ because I only did it once and benchmarked it (MFLOPS was **** and i couldn't get them high at all) actually it slowed down my phone but you should test it. Maybe your very lucky and your phone can take it
Well,I have set it to 653min-749max with screen on and 160min-352max with screen off.Testing only!But it runs like a dream if we don't take into account a small lagging when I turn the screen on and it has to change frequencies!But it's great so far.Will see how battery life goes!By the way,tried 800,806 and 848MHz,but none worked.It didn't crash or something,it just wouldn't change to it and stayed at lower frequencies(low as 246).
Thanks for your time anyway!
And a small question...How bad does overclocking affect the CPU's life?I asked around and was told that the maximum overclock for desktop PCs is 20-25%,depending on the CPU,while needing special cooling systems,and that it can reduce the CPU's life up to 50%.Given that we overclock over 40%,how bad do we damage our CPUs?

I haven't heard to much about that actually but from what I've heard it shouldn't damage the CPU at all because of the voltage adjustments but i find that very hard to believe... Talking from personal experience my phone runs as smooth now as it did when i bought it so my CPU has probably taken minamal- or no damage at all and I got it when it had just come out here in Denmark (Europe) which is about 8+ months i think? So I wouldn't care to much about the lifetime since It's probably like 1-2 years and by that time I don't think people are using the Hero anymore Keep up the good work with optimizing and your welcome

Here is the video i tried to take regarding the screen lag.
Its all real time , there is no , afaik any camera lag ( taken with sg3) , its pretty much how it looks . Also i have shown the FPS . You can see when i scroll slowly , the FPS drops to 20 or so making it jerky. if i do it fast , it reaches 50+ but not stable and not very responsive to my touch feedback either.
I have tried Bexus Kernel with OC GPU , still the same . Is there anyway to force the tablet to display at bare minimum of 30FPS ? I planned to read lot of PDF, but this jerkiness is giving me headache.
Can anyone help me ?
what rom are you running? no screen lag for me on a really old cm10 build. pretty much consistent framerate, though it is kinda slow
i think part of the problem here was B&N's choice of using a PowerVR SGX 540 GPU in this tablet. this particular GPU was also used in the entire original Samsung Galaxy S line, and is at this point 5-7 years old. not a particularly great GPU in my book. granted, we're not pushing a really high screen resolution (1024x600) but still, it's a really old GPU.
CM 11 Snapshot M5 i think. Using along with Bexus kernel.
I can lower the resolution if needed , all i want is a stable framerate display , ready to sacrifice some battery too.
I agree the tablet is kind of old , but i just want to use this as some secondary reading tablet. i have no use for it now.
Try turning off "Magnification Gestures". This has caused input lag for me before.

I would say no based on my experience. My N9 stayed between 3x-4x˚C during normal usage. That is the same temp range as my ZenFone, only did my G2 ever overheat to 60-100˚C due to its stupidity.
Although, I should mention that other owners have worse temperatures than others, along with poor screen and so on.

Yours reaches a much higher range, likely do to you using the stock build. Check CPU-Z and see if it tends to stick near the max.

That's why. On stock the core scaling is very aggressive compared to the custom kernels available here. When any CPU is kept at its max for awhile it'll heat up faster because of the voltage and blah blah. I suppose it would be normal for stock then.

i need to stop throttling from kernel is this possible ?
i tried all kernels and only underclocking delayed it a little bit but not disabled it.
btw my story :
i switched from g9600 to g965f (sd845 chinese s9 to european ****ty exynos s9 plus) because s9 screen is small. But in pubg, exynos performs like ****. i think this is just a FAKE cpu and gpu at all. After throttle in these summer days its like my old LG G5 with a cooling mod performing at peak. here : https://forum.xda-developers.com/lg-g5/how-to/hw-mod-improve-performance-prevent-t3821462/page3
35-55 fps flactuating holy crap. this is an 2018 flagship device WTF is going on. Even you can underclock SD845 to give 200.000 antutu and its still far far far better then exynos cooled with a fan (active cooling no throttle)
i was aware of this ****, they stopped sending free phones to anandtech because they uncovered this.
but i didnt know it was this bad on pubg. it seems like antutu scores are nothing to do with pubg performance of exynos. may be its about optimization or bad cpu gpu architecture for pubg.
i thouht that s9 plus has a bigger frame bigger heatsink so may be its not throttling like exynos s9, they are not talking about it on anandtech lasrhşaoırghşoeırghjea
https://www.anandtech.com/show/12615/improving-exynos-9810-galaxy-s9-part-1
I think only WhiteWolf kernel disabled termal but when phone gets very hot System turning off all applications
trying it now, seems like there is not throttle. i changed shıtty layer on cpu with a copper and thermal paste so its cooling faster but giving more heat to battery.
I've been using S9+ Duos with exynos SoC and never had throttling or fps drops on pubg... are you using a case or something that makes the phone extremely hot?
Don't forget thermal throttling is to protect the SoC... and staying on high temps for long time will decrease SoC lifetime...
If you have money and don't care about that then there's no problem on using a kernel with thermals disabled.

Nobody noticing it. Only me and other pros noticing it. i have shtloads of friends like you who is playing with 35-55 fps in throttle and they are not noticing anything. Even i have a friend with duo exynos model in gym and he is playing with 35-45 fps. drop is a different thing, im talking about FPS DECREASE.
May be you are in a very cold environment. use smooth/extreme and get fps on display (gamebench or gltools) and see massive fps decrease after throttle.
BTW your asking me if im using a case holy crap did you looked at my lg g5 mod ? aergaergt

I see that people are having mixed opinions when it comes to Overclocking the display on k20 pro. So can we have some feedback by people who used it for Decent - Long term, just enough so we can have a clear idea of whether it is safe to daily drive Overclocked display mod or not.
If you carry about ur phone, dont oc. I've heard that screen cables [if i can call it like that(probably not)]
are so small that from overclocking they can just be damaged. I would rather overclock an actual clock(wtf)
And the fact that when i wanted to overclock my pc monitor from 75hz i was able to overclock it to only 81hz... Yes i've tested the 82hz but monitor just couldnt handle it. So imagine how it would be on ur mobile.
And if u wanna just slightly oc ur display,
First u wont see any difference at all
And second ur display will start to suffer a bit.
(I would recommend oc sreen if u wanna buy a new phone lel)
Edit: i think i didnt read the topic carefully so....
Ur screen can even die

Yeah I have a similar insight but I find 75hz way more bare-able to my eyes. I spend a lot of time on my computer and my monitor is 240 hz so almost all screens disappoint me. Though I find 75 hz a lot more better than 60. Have you tried the mod for a significant amount of time? On the phone?
The main issue is the AMOLED display, i've seen LCD's getting retention marks after a long time using overclocking, but amoleds have the risk of burn-in and I would never recommend messing with this if you want to use your device for more than 1 year, I bet it would get burn-in marks in some weeks after using 75hz or above. It's best to stay safe and take care of your device in my opinion, but that it's up to you.

I didn't know burn-in issues had anything to do with the refresh rate. Maybe I need to learn more about why that happens. Other than the burn-in issues you think OC to 75 will harm in some other way?

I have been running the phone at 75hz since the start and I bought the phone in May 2019. I have yet to see any flickering, tinting or artefacts. I would say there is a risk but give the fact that over hundreds to thousands of users overclock their display on the 9t pro and have yet to report a permanent issue, it is rather safe since the voltage and current is not altered. Then again, millions of users overclock their computer monitor for decades and have yet to see any irreversible effect.

You have to help yourself for that. Different firmware, kernels, and even the different versions require different DTBO. There is no universal DTBO. AFAIK, Immensity and F1XY kernel blocks screen OC. Also, certain DTBO only works for certain type of fingerprint implementation, such as Mi9fod,Mi9fod advance,Losfod,MIUIFOD etc. Some works in terms of OC but will screw up your fingerprint, while others have the fingerprint working but OC not working. You also have to take note of the DC implementation.
Again, you have to help yourself and do some research. I would suggest you start with the standard 75hz_nodimming version and older versions of Immensity kernel and try. Do note that flashing the wrong DTBO can render your device unbootable and it might even cause the recovery to not boot.

Yeah I have a similar insight but I find 75hz way more bare-able to my eyes. I spend a lot of time on my computer and my monitor is 240 hz so almost all screens disappoint me. Though I find 75 hz a lot more better than 60. Have you tried the mod for a significant amount of time? On the phone?

The main issue is the AMOLED display, i've seen LCD's getting retention marks after a long time using overclocking, but amoleds have the risk of burn-in and I would never recommend messing with this if you want to use your device for more than 1 year, I bet it would get burn-in marks in some weeks after using 75hz or above. It's best to stay safe and take care of your device in my opinion, but that it's up to you.

What do you think about some videos on youtube that "may" prevent burnin?

I have been running the phone at 75hz since the start and I bought the phone in May 2019. I have yet to see any flickering, tinting or artefacts. I would say there is a risk but give the fact that over hundreds to thousands of users overclock their display on the 9t pro and have yet to report a permanent issue, it is rather safe since the voltage and current is not altered. Then again, millions of users overclock their computer monitor for decades and have yet to see any irreversible effect.

So it's kinda simmiliar to overclocking a pc cpu without touching voltage, right?

PC monitors are LCDs (IPS or VA panels most of the time), amoled will always get burn-in marks after some time, it's just the way they age, overclocking on amoleds is quite risky as I said before, the voltage dosn't matter in this scenario, by overclocking a 60hz amoled panel you are just forcing the pixels to update even faster than normal (they obviously wasn't made for that, you get side effects like discoloration), in theory burn-in marks have way more change to appear on a overclocked panel than a 60hz one.
Of course, I'm here just to spread info, everyone can do whatever they want to their devices, if I'm wrong on something I apologize, this is what I know from studying displays along these years

I agree with what you said. I would also like to share my experience and knowledge. I have been working in a display company for quite a while. From my experience, most of the grade A OLED displays can usually run about 20% ish higher frame rate than what is advertised at the given voltage and current. Bumping the voltage will give us a higher sustained refresh rate aka being more stable but that would usually result in a lower life span. As much as I am aware, overclocking the refresh rate on OLED should not cause burn in issues but discoloration or tinting is inevitable for grade A- and below displays. LCD however, have a lower margin of % in terms of overclockability at about 10-15% ish depending on panel type and quality.
Some of the users get green tint or high latencies when running at 75hz while the others don't. For my set, it does not have the said issues at a but there are indeed multiple users getting mild temporary tint when applying overclock. That could be due to insufficient voltage for this particular display hence the instability unlike other displays that actually shows sign of distress due to being forced over their capabilities. We can only advise to monitor and OC at your own risk as the quality of the panel used is not very consistent. I have another set that still managed 84hz on GSI Havoc without issues but my main set can only run stable at 75hz. As for those that have permanent issues with their display, it's said that they actually overclocked to 84hz/90hz so that's another story I guess?
As far as I'm aware, Xiaomi intentionally lowered the voltage on MIUI so the display can only overclock by 10-15% to a maximum of 69hz, 75hz is still possible on custom kernel and AOSP. Correct me if I'm wrong.

Thanks for the info, it really helps when someone who has direct contact with this type of technology. I also agree with what you said above but even if voltage is consistant it still is a mod that pushes the display to its limits, we can't deny the possibility of a future damage and the fact no one had issues until now could indicate that it's harmless, but it can also mean that nobody is noticing it until it gets really bad, that's just a theory tho.
I think everything was answered by our ideas, so for a short answer to the people who want to use it:
Is display overclocking on amoled safe?
-> Yes it is, amoleds could be damaged by increased voltage rather then increased refresh rate, so use it with minor dropbacks like the colors being a bit off.

No worries. I actually fixed it by dirtyflashing the current EVO X 4.5 rom(which my device was running currently)
That seems to have fixed the yellow tint as well as the refresh rate is back to 60hz.

I'm also using 82hz since I got this phone in 2019. No problem with the screen. The only problem is the limited ROMs you can use that supports higher refresh rates when you want to change ROMs.

Yes. Still no problem with my phone's screen.
Burn-in is and isn't an issue.
I've owned 3 amoled devices, loads of use and no burn-in. But that's because I don't keep it on full brightness.
But every other phone I've seen from other people, S2, S3, galaxy note 5 (twice). All have burn-in. Brightness is more likely to cause it than display hz. I've run mine at 69hz since launch. No issues.
But... Only overclock if you have the superior Samsung display. And not the cheap Visionox panel some people have.
Bought in 2020, started OC in late 2021
2 months of 72hz, 8 months of 81hz, 2-3 months of 102hz
Still in great condition as when I bought it
