[XS] Change device screen resolution, The Correct way?

I owned a Sony Xperia S lt26i.
it will lags constantly while playing some games, i think it is because of its high screen resolution. (correct me if i'm wrong)
If i want to change whole device screen resolution from 1280x720 to 960x540
I just need to change the lcd density/screen resolution at build.prop and change all apps to 960x540 compatible (included launcher/dialer) , then change the details of my model to Xperia P (which is a 960x540 resolution)
Is it this way will work?
any help is appreciate

seems not easy to get an answer ~.~

You cant change the resolution of the screen. The density is another story though.

He wants to change the screen of the application.
No need to be an asshole, you know what he means.

If you have CWM installed then make a backup. Then apply the changes you think will work. If it works then good if not restore the backup.

Q1:
CWM with locked bl will work as well? (i mean backup)
Q2:
changing density = changing resolution?
if 1280x720 change to 960x540, then
341.54 PPI (my PPI i think 340 if didn't rmb wrong) need to change to what value?
Edit: Checked, LCD density is 320, so what value i gonna to change to suit the 960x540?
Q3:
i tried to change before, but seems Launcher is not suitable for this resolution and those apps like subway surfers still is 1280x720 (define by the watching the FPS (2x~4x) ), so means i need details of my XS to XP then the apps need to re-download?
Thanks for reply

For unlocked bootloader, CWM backup works on latest version. I think version 4 is newest
I have no knowledge about resolution. Maybe check white paper, on Sony site, for the P for its specs.
After build.prop changes reinstall apps. Market should see changes.
Good luck

Extra:
LCD density increase = Screen resolution decrease = Performance increase = Visual quality decrease?
is it this statement correct?

You can't decrease or increase screen resolution. The number of pixels are a hardware thing. You can change DPI, but that won't have an effect on the performance, but on how big or small everything will be rendered on the screen.

Oh ya.. This is the answer i want :crying:
It won't increase performance then no point to change it
that means we can't play subway surfers with full fps.. (even lose a samsung galaxy s)
Question Solved.

I hope you weren't using subway surfers as your lag test. I just went to the store to download it and every comment about it said that the app made the phone lag/laggy.
My kids play temple run, looks similar, and no lagging here
Edit: I just played both and I have no lag. Game played smoothly. Only played a couple minutes though

yeah, temple run is constant 60fps and never drop, asphalt 7 still ok, but not constantly smooth also
max temp for cpu is how much? i would like to set it higher to prevent cpu decrease while gaming :silly:

Need help with overclocking

Hi!
I want to somewhat improve the performance of FPse and ePSXe on my XPlay, and it seems that CPU overclock is the way to achieve it. The problem is that I am completely inexperienced in this sort of business.
Could you please advise on the simpliest procedure and/or point me towards some easy-to-understand guides?

Hmm, that could be a bit tricky because the Xperia Play only has a 1GHz processor..
That aside, are you currently on marshmallow firmware? If not, what firmware are you on, does your device have root access, and a custom recovery? Or is it completely stock. Please provide these details so that may be able to help you further..
Thanks
---------- Post added at 12:28 PM ---------- Previous post was at 12:20 PM ----------
Oh and please also provide details of current config settings for fpse and epsxe... Ty

Many people (like the author of this video: https://www.youtube.com/watch?v=sQIxsBTEDq4) claim that overclocking is efficient. So I decided to give it a try.
I am using the stock firmware - 4.0.2.A.0.42
The only non-default thing is root access. I didn't do anything about recovery, so it is probably stock.

Ok, As for your device, It clearly is stock..
As for your settings in FPSE and EPSXE, which one do you use or plan to use the most?? im guessing whichever provides better compatibilty/speed/ etc??
If So. i would like some detail of your config settings within the EPSXE app first..

As for emulators, I'm using them both. Compatibility and overall picture quality are better with ePSXe, while FPse is faster, hence sometimes I have to use the latter. For my favorite Colony Wars series, for example.
FPse settings:
Framelimiter on
Screenfiltering on
Enhanced 3D rendering on
Hardware acceleration on (although doesn't seem to do anything)
Boost high res games on
Dithering on
Others are off
All the above is in Software smoother image mode. OpenGL and Software HD are unplayable for most of games.
The setting may vary from game to game, but the overall standard is this.
What I want to achieve by overclocking is to make graphics-heavy games (Colony Wars, Panzer Front, etc.) to be playable fullspeed in OpenGL. Or at least in software mode of ePSXe. Getting Ocarina of Time to run decently in Mupen64 would be good too.

ePSXe settings:
CPU Frameskip off
MME Enable autodetect
Screen ratio stretch
Screen color depth 16
Top/Bottom bands real PSX
VR modes disabled
Video Renderer hardware
Internal Resolution 1x
Video Filtering enabled
HW/Soft Threading Mode none
Plugin subpixel precision disabled
PSX Dithering enabled (not always)
Sound quality less
Sound latency normal

Well, you might have to compromise a little bit of graphic quality for performance or vice versa..
But generally if you're looking to increase performance (speed of a game) you need to down tune the graphics settings..
In FPSE video renderer, set it to software (sometimes hardware can slow down performance).. Give that a try.
Boos high res games, off.. (if that increases performance then keep itnoff, otherwise leave it on..
Let me know how those work out for you

Its not exactly the point. I've been using those emulators for three years now, so I know enough about quality/performance balances. What I want to do not is to expand the usable quality range. And for that I need to overclock. Advise on that please. Anyone?

Only way to overclock Play is to flash custom kernel which have overclock integrated. Doomlord is up to 2GHz,, Lupus is up to 1.6GHz (or few more that you can find in sticky threads). To be able to flash custom kernel, you must unlock your bootloader (if you can, it depends on model of your phone ...)

What bakisha said. Unlock bootloader, flash custom firmware.. Thats the only way youre gonna really overclock it

Thank you!
1) How do I check whether my bootloader is unlocked (it could be)?
2) How do I unlock it?
3) Which custom kernel should I choose?

Lowering res to 1080p

Hello guys,
is there a way to lower screen res to 1080p by default (for system and everything running)?
Thank you

You can google "wm size" and "wm density", for 1080p you might as well set the dpi to 420. I don't recommend you do this on stock rom though.
If you think this can help you save battery life, it won't.
If you want performance, the gpu is strong enough for most apps that you probably won't notice any different between FHD or QHD. For 3D gaming, HTC's boost+ can lower the game resolution to 1080p.
Indeed, if you change the resolution and density, they can make some apps acting weird.

It doesn't open apps faster, but it can make the UI smoother (transitions/scrolling). This is entirely subjective of course, and then there's the variables of different rom/kernel combinations

ZUK supports 4KHDR @ 60fps?

Why is it that despite of having same configuration as OnePlus3, ZUK can't play 4KHDR @60fps as smooth as OP3? Though it can, after some tweaks, but not as efficiently & smooth as OP3(unrooted). I used same Version of MXPlayer and same file for comparison.
I tried all custom kernels available (Heliox,Jaguar,Darkmoon) and Latest versions of major ROMs(RR,AEX,ViperOS). And still didn't match the playback quality of OP3.
Please tell me if there are more kernels or ROMs yet to be tried, which can bring substantial step-up in performance, or which will just Play 4KHDR @ 60fps.
Overall, the User Experience is super-smooth but
this small thing is eating my brain :crying:

First of all, You are comparing "THE BEST" SD820 phone with probably the 3rd or 4th best SD820 phone (antutu wise). Secondly, even on the OP3, why would you choose to play 60fps 4K videos that too HDR ones?! That's ridiculous for anyone. I'm hoping the logical explanation to why you're doing this is to kinda benchmark the phone. But even then a lot of SD653 and SD810 phones can breeze through this benchmark easily. It's even more ridiculous that you've tried almost all roms and kernel combos just for a luxury video playback.
Anyways coming to the point, I tried the Sony 4K 60fps HDR Swordsmith video on my Z2+ (AEX4.6 Official with HelioX 3.18.80) via MX with HW (not plus) decocer and the video was running smooth AF. Infact, compared to playback my friend's OP3 running OxyOS 5.0, my Z2+ had zero hiccups throughout the video while the OP3 had 2 or 3 towards the middle. The interesting thing is that I achieved these results while running CPU underclocked to 1996 & 1401. But technically speaking that shouldn't be a problem in the video playback coz HW decoder runs exclusively on the GPU. Concluding my point, don't watch ridiculously high quality videos on phone and don't change roms and kernels to achieve desired playback, just adjust and optimize them.

My point on playing the best video quality I have, bcz ZUK can, why not. I tried LG Cymatic Jazz HDR to test the playback(details attached).
Back when I had ZUI, it could not play the video at 60 fps. But when I flashed first RR, I was surprised by the result. In MX Player Pro with HW+, it could play super smooth with absolute 0 lag.
Then came updates and further more I flashed many ROMs but never got that playback. Changing kernels didn't help. And now I've same ROM and kernel as you do, because you know.
The fact that you can play 4KHDR @ 60fps, may be bcz ur video isn't having 10 bit color depth. Please attach your video details, I wanna see. If our videos are of same quality, then I may be having some other issue.
Its strange however, you're playing 4KHDR on HW.
Also, do you have Substratum theme or Xposed modules installed? Just curious if these affect performance in any way.

Is it possible that Xposed and Substratum are somewhere causing pain to the system?
Also, I once changed some screen values through Kernel auditor and tried to undo that. I don't know if they're default now, I'm attaching SS just tell me if they're same. I'll try uninstalling Substratum and Xposed and keep system as Lite as possible and then check.
Thanks for your attention and help

Substratum can have some slowing effect on GPU due to its theme engine but that'll be possibly unnoticeable in a SD820. Xposed should be harmless (afaik with my previous phones) unless you are running GPU affecting modules. I don't use substratum because I was perfectly happy with CM theme engine and now that it's gone, I'm not so keen for a replacement. Xposed went meaningless after Lollipop & the birth of Magisk (for me atleast). And lastly about Screen values in KA, they don't have any effect on GPU unless ofcourse you're running grayscale which might actually save you some power (but might be unstable). If you want to reset the values, just uncheck apply on boot under screen settings and reboot. FYI, I ran almost all KCAL profiles I found online and "Perfection" (that's the name of the KCAL profile) for OP2 is giving the best visuals in my perspective. Try it if you want. Happy to have helped you ?✌?

Imo the zuk z2 is not as good at playback than I expected. Even 1080p60 video drop frames constantly at 2x playback speed
Also the phone dont have a hdr screen so why even try to play hdr content anyway

Playing a 60fps video at 2x speed would mean 120fps, that's out of our screen limit. For that purpose display needs 120Hz refresh rate as in New Razer phone, or some frames will get skipped(frame drops) as you noticed.
And the reason why I wanna play that, I search of playing that thing smoothly, I've learned many things. It simply gives me satisfaction.

I removed Substratum and Xposed, even Shox audio mod, but result was same.
Though Performance as CPU Governor gives 100% results, but you said you've Under-Clocked ur CPU to 1996MHz, that did surprise me.
Which CPU & GPU governor do you use? Also which I/O Scheduler? I'm curious.

Question Bad resolution on Cod Mobile.

And not only in that application in other applications it also works low resolution like pubg do you think it has a solution? Because I bought this tablet basically to play their games.I am thinking of selling it and buying the iPad because my girlfriend has it and all the applications are at the highest quality here, I feel that it is not optimized and what is like a large mobile.The tablet in hardware and price quality is much better than the ninth generation iPad and has incredible speakers but if it is not accompanied by a good operating system it is useless

It did choose lower resolution on some games, but there I could increase it to max level manually in settings.

Same problem here on cod and pubg. Have you found any solution?

Just check anti aliasing

I tried all graphic settings, even antialiasing. Uninstall and reinstall the game, fabric reset the Tab but no changes. It is like the game runs in 480p and It doesn't recognize screen resolution.

Maybe the game simply isn't optimised for a tablet very well? Maybe speak to the developers. I don't have any resolution issues on anything else.

I have the same problem did it got fixed? Or did you get a solution??

No, no solution for me.

I've read that this is a known issue even on the Samsung Tabs so it seems to be a screen related issue in general.
