Hello,
I have gotten this MHL adapter for my Note 2 about 2 weeks ago and it works decently. The problem I have noticed is that when I play GTA 3 or GTA Vice City is that the framerates seem a bit jerky to me. Im not sure if its just me or if its the mhl or if anyone else has this problem. Is there anything I can do to fix it?

Dear X-dude,
Same here...
No problem with videos or other apps but games have less framerates when using mhl... I am not satisfied with the performance of game playing using mhl and sixaxis controller on TV Screen... Couldnt find a solution till now... I had same problem with Note1 also...
Kind regards...

MHL is not 'up to par' when playing video games, the fps just can't keep up. Playing videos though will work excellent! I use my N2 all the time to stream and play videos and music on my HDTV, looks and sounds amazing! Video games...not so good....
its not the MHL that is the problem.
the problem is the fact that the device is running in mirror mode. if you're running the TV at 720p as well as the phone at 720p, that means that the GPU now has to render twice as many pixels (ie. 1843200 pixels instead of 921600 pixels). it only gets worse if you run 1080p as it will have to render a little over three times as many pixels. doing that is far too demanding for our overclocked mali400 GPU, which is one of the reasons why it lags.
basically, the only device available at the moment that would have reasonable framerates in mirror mode based on GPU power alone would be the ipad 4th gen. i personally dont like ipads, but hardware wise, they do have a beefy GPU. the adreno 320 can keep up well enough, but isnt quite as quick as the powervr chip.
the malit604 might be able to do it if samsung can optimise the driver if they use it in the s4 next year, but at the moment, the performance of the mali 604 isnt much faster than the adreno 320.

That doesn't make any sense.
Mirroring in that case = Output twice what GPU rendered once. Mirroring isn't involving any extra work to GPU, (not sure about 1080p output, but i guess that all rendered in 1080p instead of 720p then downscales to fit the screen of device, performance-wise its only a tiny amount worse than having 1080p screen on device). But any output (and MHL is included) has latency, when you output videos it is not noticeably because you don't interact with videos, but when playing dynamic game you'll start to notice lag between interaction and game react to it.
It is only applicable to Mirror output, extended screen surely will take part of GPU perfomance, but not half of that - it is depending on what you doing. 3D games is involving much more computing than several layers of 2D in android interface or media player.
Need some technically adequate investigation on FPS drop and MHL latency

Interesting. So there isnt much to do then to increase framerates on games?
Not sure where I read this at, but I was sure to have came across someone saying that the 1080p output is only at 30hz.

I also heard something about that and does the 30hz cause dropped frames? Also im pretty sure my mhl outputs at 1080i and not 1080p which makes a difference?
1080i is the culprit.

Souai is right. If you would like a demonstration, do the following. Install the Electopia game/benchmark. When you start the app you will be asked if you want to run it in WVGA resolution or full screen. Try WVGA first. On the next screen choose 'benchmark' mode. Let it run then note what FPS you scored. Next run the benchmark again in full screen mode and note the (lower) FPS. Next, plug your phone into your tv using MHL and run both benchmarks again and note the lower FPS scores.....see? When plugged into a tv via MHL it is having to work much harder.

It sems there is a fps cap on our Desire HDs. In games and benchmarks, the limit seems to be around 59-60 fps. Is there any possible way to remove this? And yes, I know our screens are 60hz, but still...
Under ROM development as I understand it is something to do with kernels...
Sounds like v-sync is on. If that is the case and if it were turned off to allow more then 60fps you would get screen tearing and screen tearing looks terrible.
V-sync is a good thing, it keeps frames that are drawn in sync with the refresh rate of the screen.
There is no reason to turn it off, maybe the menus and stuff will be faster but definitely not smoother.
That's not always the case, my friend Generally i'm more interested to see what type of framerates this baby can hit!
Well that's true, in that case it will have to be turned off. In WinMo it was a matter of changing a registry entry but on Android probably more complicated. Like you mentioned, a modified kernel most probably.
I would actually be interested aswell in seeing what this beast can do to.
Hmmm...me ad my friend were experimemting around with our phones, I have a Desire Hd and he has a Galaxy S....generally Galaxy S is more powerful in 3D graphics. However, even though he built a custom gingerbread rom, my cpu was faster (quadrant rated mine 6600 at 998mhz vs his at 1024 mhz giving 5400). Another interesting find was that overclocking q hummingbird decreases gpu performance to speed up cpu operations. I assume the gpu is underclocked to provide more power to the cpu. However, at extremes (1.6ghz) it seems his gpu also overclocks, thus crashing the system. I was thinking if it were possible to overclock the gpu on a desire hd, or at least reroute power from the cpu to the gpu via software codes...

Hey guys!
I just wanted to know if scaling down the screen resolution has any impact on the battery life. All of you who have scaled it down, is there any significant improvement in the battery life?
Sent from my LG-D855 using xda premium
There is an battery improvement but some Apps look horrible with This solution. I am back to 1440p and give a f**k about these 1 or 2 hours.

Is that 1-2 hours of SOT, or just usage?
This would all depend on the way you use your phone.
A. If you're a heavy user, (games & movies n stuff) then lower resolutions would benifit tons.
B. If you're a light user, (texts & emails n stuff) then the higher resolutions are very efficent.
There is a common misconception going around about this screen requiring alot of power.
The screen isn't what is draining the device so bad, it's the gpu powering the immense amount of pixels that is causing the power drain.
Now taking that into consideration, there is 3 things to keep in mind.
1. You're still lighting up 3,686,400 mini lightbulbs (aka pixels) no matter what resolution you run at.
2. Lower resolutions = less power draw from the gpu, mostly when the gpu is under higher loads.
3. The gpu doesn't require much power while under lighter loads
So to sum it up
Higher resolution + Very graphic intensive = Heavy power draw from the gpu
Lower resolution + Very graphic intensive = Medium power draw from the gpu
Higher resolution + Not graphic intensive = Low power draw from the gpu
Lower resolution + Not graphic intensive = Low power draw from the gpu
As you can see, under lighter loads 2560x1440 is extremly efficent and preferable by myself, but under heavier loads (games and stuff) 1920x1080 is far more power efficent on the gpu (if your games will even run), once we get a custom kernel for our phones a slight gpu underclock would be MUCH more effective than lowering your resolution.
All this talk of lowering the resolution to save power is rubbish, it doesn't work. Its just a placebo.
By far the biggest cause of drain on the battery from the screen is the backlight, not the resolution. Changing it to a lower resolution doesnt actually change anything, the GPU isnt even trying even at 1440P, it never scales past the second step (330MHz) in 2D. The only thing stopping the GPU from being able to display 4K or even 8K is the bandwidth, not the GPUs power. 2D is effortless for the GPU.
If you reduce the resolution to 1080P the GPU has to rescale that image to 1440P in order to fill the screen (the actual screen resolution is fixed and cannot be changed). All this does is add an extra layer of processing and costs you processor cycles.
In games this changes somewhat, but the effect isnt as big as some like to think. The GPU is still memory bandwidth limited in 3D even at 1440P, not power limited. To prove the point in Basemark X the G3 scores higher than the N5 and almost as high as the M8 and S5, despite having double the pixels.
I bought it for the resolution.. I'm not turning it down.. Otherwise I would have just bought an S5 Or a freeking iphone lmfao

Well im just asking if i should get it or no.
I want to replace my laptop with it and a small keyboard. 10.5 LTE with Supposatly the Samsung exynos that is a 8 core but seem it not in reality like samsung lied
I want to hear the good and bad.
:laugh:
EDIT : Hello bonami2 , I posted the reply below before i realized it was you from NBR Forum, Welcome to XDA
It depends on what you want to do, if you want to watch video`s most of the time, get it, it has an amazing display, if you want to browse the internet most of the time, dont get it as the oled display eats the battery when it shows white, you are better of getting an lcd tablet, gaming kills the battery on all tablets so it does not make that much difference between oled and lcd.
You can get browsers that have night mode, where white is black so it save a load of battery power but it looks like crap.

Don't get it. Poor battery life in general. Horrible idle battery life with Lollipop. The CPU is outdated by now. If you have to get a large screen tablet right now, go with Ipad Air 2 or Google Nexus 9. Moreover, we're slowly approaching the holiday season. Normally all new products are released in the second half of year. Even Samsung's Tab S replacement is rumored to be arriving in the second half of this year.

The new cpu for the tab s2 is supposate to be only 50% better in singlethread. and Enable the hmp to use the 8 core and have a higher clock and new architecture.
But at the end my 4 old Galaxy nexus from samsung from like 2011 2012 is still able to browse website with it old crappy dual core ahah. with 1/6 the singlethread
Poor battery life well i seen 15 hour of movie time with black movie. Using Dolphin and A night mode should allow to have better battery.
Not interrested in any apple product even if i was forced to.
At the end there is nothing on the market that seem worth the money. Except the tab s and i do know how to save battery with the recent research and own experience with my old Amoled phone.
So im gonna try it and return it if im not happy
And put the money toward some gpu
Anyways im getting it mid july and i heard it could be released in that time frame. Will see.
Thank you for all the negative
I have no problem with battery usage. It lasts a long time for me.
Tablet design is one of the best, the screen is fantastic. No issues with lag in normal day to day usage.
Websites with heavy usage of ads and graphics, can exhibit a little lag, but nothing out of the ordinary or that bothers me.
Sound quality is great. Touchwiz isn't the best implementation of an interface, not compared to HTC sense on my M8. However all in all quite happy with it.
And yea it me from nbr decided to post in case i could learn other stuff Google is good but we never have enough info
Thank you

Tested something with my nexus 5
Chrome is laggy when moving page the finger move faster than the browser
Dolphin go as fast as my finger can go on the screen and doest lagg at all or almost. Sure heavy page are slow to load.
Im mostly interrested in the multitasking thing samsung made i tried it on the old Note 2 and it work fine
Ps i have a 6000mah external battery
Gonna use it to power the external hdd im gonna get later down the road.
100% laptop replacement with storage everywhere

yea im staying aways from that crap 4:3 ratio i have no idea how people can like that i had a laptop with that ratio for about 10 years until the screen hinge broke + the battery + the screen itself go humidity stuck in the panel and the fan started rattling lol
Ended using it as a server and finnaly recycled it after it started sounding like an airplane
My battery monitor says around 12hrs video playback at hd resolution depending on how bright the video is, Harry Potter=Yes , Dune=No

My battery is ok. Not good overnight on standby so charge it or switch it off.
I get an occasional freeze on lollipop when watching films. Was no problem on kitkat. Hope the next release fixes the movie issue.
Love the design. If the s2 is even better I may be tempted - but not by a smaller screen (as suggested).
That's out in the next month or 2 isn't it? Why not wait. Then you can buy my S lol

First of is this a very good tablet.... yes. There is a handful of flagship class tablets that are made for android and for the most part they each have small advantages and disadvantages over each other. The best thing you can do is figure out exactly what type of stuff you want to do on your tablet.
Second this tablet is a Big.little 2X quadcore, so calling it an octacore is both cprrect and deceptive at the same time. Honestly I have no clue if Samsung enabled HMP (heterogeneous multi processing- the ability to use both quad cores at the same time) or not but I have noticed that the tablet is usually more gpu bound then it ever gets processor bound. In practice the faxct that there are better processors out there (tegra k1) does not mean that this tablet can not handle almost any program you can throw at it (that runs on it-- no tegra zone or xcom).
Lastly I would not recomend this tablet, the nexus 9, Nvidia shield, Sony z4, or any other android tablet as a laptop replacement. Or to be more precise I could not use one in that role. It has nothing to do with speed, this tablet is far faster then the pentium 4m dell I used to have. It is not so much the size of the tablet the 10.1 inch screen is not much different then some ultrabook screens I have used. The main issue in using an android tablet as a laptop replacement is Android. If you could load linux on this tablet amd run it then it might be a little closer to a working replacement, but even then the arm architecture severely limits program compatibility. The lack of even 1 full sized usb port (yes I know it has otg) limits accessories that can be used.
If you only ever need to do some very light document editing, then yes this can replace a laptop. If you need to do more then that and you absolutly have to have a tablet form factor then buy a surface 3 (never a 1 or 2, windows rt is useless) or other x86 based windows 8.1 tablet. If you want the best of both worlds then for the price of a galaxy tab s abd a keyboard you can get a convertable tablet/laptop and have a laptop for heavy workloads and a tablet for fun all in one.

10hour battery life on a laptop is pretty hard to do
The review in the link below quotes approx 7.5 hrs internet browsing which is almost the lowest, but the video playback is the longest, have a read of the full review if you have not yet.

If younare looking for multimedia playback (videos and songs) and some internet browsing then yes you are correct, you don't need a full sized laptop. Tbh you really do not need a seprate bluetooth keyboard for thst either and that was partly what I was basing the thought you might want to do more then that on the tablet. Word processing for a document of any reasonable length, is lously on android even with a bluetooth or usb otg keyboard.
If you want to watch movies or listen to music on the go do not forget to buy a microSD card, this tablet supports up to 128GB but 64GB is a far better value. 16GB (or even 32GB lte model) is not enough memory after programs and the OS to store more then a few hours of moderate quality (480p-720p) videos and evem kitkat reads multimedia from removable storage with out any need to mess around with roms or root. Heck it is the one thing Google thinks should go on a microSD card, that and pictures.
The settings allow you to lower the resolution. I lowered the resolution to 2340 x 1080 and I don't really notice anything different.... Would this increase battery life? If so, how much?
It will definitely increase battery life.
How much will it increase depends on your usage and your apps installed. It should at max give you 10% increase.

It is well and widely known that lowering resolution won't give you increased battery life. At all
Ah thanks. I come from an xperia z3 so been using FHD screens only. I was interested in the XZ1 compact back then and one of the key points from reviewers is that the lower screen resolution(720p) saved a lot more battery vs the XZ1 at 1080p.

I think the misconception is lowering the screen resolution vs a device that maxes out at a lower resolution. Maybe it makes a difference for OLEDs...but for LCD screens, all if the pixels are still illuminated, so there's not much difference there.

Because Samsung's can do it.
Nothing but hype for the misinformed and ill-advised.
[Dopey voice]"Bruh...look what my phone can do to save battery life. Can yours?" [/Dopey voice]
Using lower resolutions use less power bc they use less gpu computational power. Youre not saving anything really from the screen itself. Think of it this way does your computer/laptop use more power running resource intensive applications or running idle?

Not that the resolution that saved power. If Sony could put their 3840x2160 resolution display into 4.3" size of XZ1 compact it still would run longer on battery than any 6.5" sized phone from similar battery even with 720p display. Because it's sheer size of screen that saves battery, not the resolution. 4.3" vs 6.5" is hefty difference. One needs more light to make 6.5" display emit light than to make 4.3" one hence one need more power.
Think about it this way, if resolution would matter then XZ Premium and XZ2 Premium would drain their batteries in a matter of minutes with 3840x2160 res displays. Right? But they work almost as long as say Galaxy S9 Plus or Note 8.

It not works like that. When your phone renders picture in 720p or 1080p it doesn't do it sitting idle. It still consumes power when rendering picture 60 times a sec. And its GPU still runs at 200MHz, maybe it needs like 230 or 250MHz for rendering picture in 1440p but is 250MHz vs 200 MHz a huge difference? I doubt it
It's not like 1440 picture rendering needs full GPU power but 720p or 1080p can be powered by idle GPU. Never was, never will. Ask devs in http://forum.xda-developers.com/android/software-hacking if in doubt
In reality ability to pick your resolution for battery life is a gimmick and doesn't really do anything.
There were no proofs that phones live longer from same charge when it's resolution lowered. Maybe it works for constant gaming, like playing games in 720p on a 1440p screen will bump battery life. But in other cases no
Taking only power consumption from the display alone, there is no different between HD, FHQ, QHD. The different is that if a game or any apps(or even system app itselfs) runs at HD, it will need less graphic computational power than running at QHD (once again, its not about the drainage from the display, its from GPU).

in reality, it's bull****. learn how GPU works. Try to ask Google devs if you don't know. They do habitate here, at XDA
It's not like it renders something and then goes to sleep turning cores off as CPU does. Instead GPU renders frame 60 times a sec and uses 203MHz either your resolution is 720p or 1080p. It can't lower frequency to 100MHz magically because it's not designed that way. So it consumes as much power working at 203MHz either rendering 720p frames or rendering 1080p frames.
Hence no battery economy achieved

Hi there! I have a Galaxy Tab S4, as you can imagine. I use it as my gaming device. The only game I play is Rues Of Survival. And well, Among us, but I don't even take it into consideration as a demanding game.
The tablet is not rooted but I debloated it with adb as far as I could. Android 10 on board.
Probably this crappy game became so poorly optimized that the performance degraded over time.
Now I am at a point where it's pretty unplayable even if I lower the resolution.
Let's see what I have tried so far.
I have checked the usage of CPU, GPU, temp and FPS with the game launcher plug-in. I have an average of 60 FPS with an average CPU usage of 8% and an average GPU usage of 80%. The problem occurs during crowded scenes. The FPS drop to 30, making the whole thing sutter really hard, the CPU usage stays the same and the GPU usage drops to 60%. WHY THE HECK?!
I have tried a couple of different resolutions (the game does not specifically states to how many pixels correspond each d*mn option) with close to no improvements. The graphics got really ugly, obviously.
Should I try to root and disable DVFS? Should I root and lower the resolution of the whole tablet to a normal fullHD with terminal? Should I stop complaining? Should I quit playing? Should I get a new tablet?
It seems pretty absurd that a game that I was able to play on my Galaxy S6, now got so demanding. Or that a 500 euros tablet aged so badly in two years.
Are those 2 free GB of ram out of 4 not enough to handle the game?
I can play it quite flawlessly on my OnePlus Nord. But this is NOT an option. The hardware specs of the two devices should be comparable. What mostly changes are the screen resolution (lower on the OP Nord) and the ram size (double on the OP Nord).
I doesn't try that game, but I played others (pubg (highers settings), stardew valley, this war of mine... etc), and I have not had problems at all. I'm stock. Have you try game booster?
