I'm testing the resolution to 4k and it seems that it looks better than the default 2k. That if the battery goes down something faster.
If you want to try is easy. With adb shell (pc) or console (mobile) put this:
Adb shell wm size 2160x3840
Adb shell wm density 640
The first line is for resolution and the second for density. Never lower the density below 600 with 4k resolution, if you do already know .......... launcher loop and format the mobile.
For mobile by console (app terminal) ....
First enter as root with "su" without quotes and commands:
Wm size 2160x3840
Wm density 640
If you want to return to the default resolution and density
Size wm 1440x2560
Wm density 560
Note that if you do not change the two lines of the dpi option of the build.prop file, some options of the launcher (lock clock and something else) will be seen with the default dpi of the rom (560).
If we change the resolution will not work the screenshots, but by third party app's if (google play). The screenshots are output to 4k and not to 2k.
P.d: The normal or reasonable dpi for 4k is 800-840.
P.d2: Do it under your responsibility (if you do not know, do not touch)
P.d3: The youtube app the maximum that it offers are 2k.
Edit:Really is a 4k screen? Could you implement 4k in the kernel as in xperia z5 premium?
Le max 2 screen is a 2k not 4k
So is it possible to set resolution to 720 or 1080p to improve performance and battery life?
I Issued those command with no error/success and couldn't find option for 4K in video settings. Did I miss anything?

Good question. 720p would be ideal as 2K (quad HD) is a direct multiple of 720p (HD), so scaling would be no problem.
Hello,
I change the resolution to Full HD
Adb shell wm size 1080x1920
Adb shell wm density 420
I use the Pixel Launcher and I haven't problems, but I test with default launcher and was deformed.
I don't see how you changed it to 4K when display does not have that amount of pixels... can't you smell this smell?

Heyyo, err... It's called downsampling. It's a technique used generally on PC gaming to improve texture quality and lower aliasing compared to using post processing like FXAA or SMAA as those can have a smear or blurred effect to them sometimes.
Nvidia have Dynamic Super Resolution which is a driver software based solution
https://www.geforce.com/hardware/technology/dsr
AMD went the hardware route so there's less performance hit but more limitations on resolution. Virtual Super Resolution
https://www.amd.com/en/technologies/vsr
With that said? I think the gains on the Le Max 2 downsampling 4K UHD to QHD (2K resolution is technically 2048x1080 also known as 2K DCI... QHD = quadruple HD and HD is 1280x720) would be quite minimal since the pixel per inch of this 5.7" QHD acreen is already so ridiculously high compared to a TV or computer monitor.
open build prop editor,
Add below line in it,
sys.display-size=3840x2160
Save it,
it should start working right away, if not then reboot after saving the build prop editor line.

Refer screenshots for your reference.
But would it make any difference in terms of definition and colors as out beloved device's display is limited to 1080p i.e. Full HD?
Yes, you will notice the difference in terms of sharpness, more vivid colours.
Cast your videos onto TV, you'll be surprised.

People will think how can it give more resolution than the screen's highest resolution, but guys it's not just about resolution, it's about sharpness and colors which you want find in the full hd alone(no doubt it's best) if you compare them both you'll find the difference
Which app did you use to do this i can't do it?
So does it only supersample the video from 4k to 1080p, or everything is in 4k now?
What happen if we screenshot the phone after changing that? Is the screenshot still 1080p pr it's 4k?

If it doesn't work for you, then it must be kernel specific problem, it works perfectly fine on AEX ROMs(both nougat and oreo)

I'm creating a bounty for enabling native 2K or preferably 4K.
The resolution/dpi emulation still does nothing more than resize the xxhdpi resources (not even the xxxhdpi), so it still isn't as good quality as 2K displays on other phones.
Moreover, VR (the only real purpose for a 4K phone) is terrible. True, the screen door effect is gone, but at the cost of blurry less defined images same as a 1080p phone. Only Youtube and finally Netflix are able to use the 4K but other apps and games are unable to use the higher 2K resources and downloaded VR movies are fuzzy. Completely disappointing compared to my 2K phone. Also, with the emulated 2K or 4K, Daydream becomes tiny in the bottom center of the screen.
I believe the kernel controls the screen properties, but not sure if there was something to do with it in the ROM for this phone. While I'm sure I could figure it out with all of the easy handy guides, I don't really have time to do the research on how to do it myself. So, I'm creating this bounty.
I'll start with committing $50 to the person who releases the first stable one, but still donate to a second placer
If anyone else would like to sweeten this pot please post how much you would contribute.
I think it's a problem of native 4k apps, not the phone.
You can put it in 2,4k using adb commands, search here https://forum.xda-developers.com/xz-premium/themes/mod-change-default-resolution-to-4k-root-t3618843, but you need apps for that. I have Bobo VR Z5 and it's working perfect in 4k and in 1080p, but only without screen protector.

The adb command is just emulating 4K with the lower resolution resources as said in my top post.
This is how Daydream looks in emulated 4K https://drive.google.com/open?id=1i531VadSbzzu1Or1CMMvBYez5VFi_Mkp
I'm sure without the screen door effect you may feel you're getting 4K VR, but it actually 1080p.
For example, I take 4K 360° photos. the text on distant signs is readable on my 2K phone, but not on this XZP.
Awesome! Hoping this will attract devs to look into this.

It's pretty sharp. It's better in emulated 2k/4k, but good enough for 1080p. At least for me.
Also just to add, I noticed that if you use GMD Gesture Control and calibrate the screen, you'll see that the app reads the screen as 4k. (Even when on stock wm size)

That app probably reads the pixel size rather than the set resolution. AIDA64 also reads as 4K the first time, but later shows 1080x1920 or whatever emulated size you set.
When doing the Daydream fix, it also changes the screen from LCD to AMOLED.

true that but even when on emulated 4k you get just as good display as 1080p, its still even not as crisp as other 1080p but cant tell difference, still with emulated 4k just to look at "enhanced" 1080p sucks!
plus you lose more battery than native 2k phones! i bought the phone because of its screen and I cant enjoy 4k at all times, or at least in the UI or any other app that I want in 4k....
im disappointed i really wish there is a fix to get native 4k...
I AM willing to throw in a 50$ as well if some one fixed this (as long as there is a root with TA backup (just in case the fix needs root to modify the kernel- I dont wanna lose DRM functions)

Excellent, and totally agree!
Now the bounty is up to $100.
Let's get more people. We can't be the only ones disappointed that Sony sold us a 4K phone *only in 2-3 apps that is actually locked at 1080p.
Could it be possible to just make other apps 4k by heavily editing them? Like the VR apps. If doing it system wide is too difficult then maybe editing apps might be easier.
I'm curious anyway, who can actually tell the difference between 1080p and 4k on this phone? You say 1080p looks better on other phones, so does the 4k look just as sharp as that 1080p? Also, how do we know Sony isn't just using the emulated 4k when it gets enabled? Not every photo in the album is 4k so how would it enable?
I did take a 1080p photo and a 4k photo and noticed a difference but I wasn't convinced. It didn't seem like a huge difference like it does against a TV/monitor at 4k. Especially on YouTube I cannot see the difference majorly when going from 1080p to 4k but can others? If 4k is difficult to make happen then maybe we could push 120hz at 1080p since it was said that the X series of devices have 120hz displays it's just disabled for some reason. The page needs translating but it shows 1080p at 120hz as an option. This was mentioned in a previous thread but I don't think anyone was interested in it. I think that this has a higher chance since this image exists.
Thats my thoughts about 4k on this device anyway. I think at this point 120hz might be a better option but that's just my opinion. 4k is great but it's only limited at the moment.
https://gazyekichi.com/2017/07/26/画面さくさく！「xperia-xz-premium」は「120hz」に対応している/
here is the thing, true that its very hard to tell the difference between 1080p and 4k on such small screen, so I took screenshots of before and after 4k mod and placed them together on my 24 inch monitor side by side and still can barely tell the difference even on huge screen which proves that its not 4 times better quality so its really fake 4k!! only time i can realize the difference is when i zoom in on both pictures and see that some details are washed out and more "pixel" looking at 1080p while on 4k mod still manages to show more details but then again, such difference in sharpness and detail shouldnt be so hard to notice since on my monitor I can easilyyy tell a difference between 1080p and 4k gaming on my VSR (virtual supper resolution) even virtually on my screen modded 4k has a lot more difference that stock 1080p
while even modded 4k on this device can barely show a difference, so might as well change that in a native way I really cant wait for a fix
PS: running 1080p on 1080p screen looks better than running 1080p on 4K screen (if screens are same size) - proven.
so down scaling the 4K screen of this device to 1080 will make it look worse than other native 1080p screen which buggs me, the least they could have done is add an option like samsung did to just adjust the quality as you wish... I hope they add that in the next update
Yes I agree 1080p on a 4k screen does look worse. On most TVs it doesn't but on my Acer predator 28" 4k monitor it is very noticeable that 1080p looks like 720p when duplicating the screen next to my 1080p monitor. The desktop does look noticeably blurrier. However, 1080p content on the 4k monitor doesn't show a huge difference so I'm not sure what that's about only playing games and the desktop look bad at 1080p. Maybe the XZ1 could have been a better option but even still know that I have the second 4k mobile device on the planet and the only 4k HDR device is still cool. It's certified to be 4k so it can't possibly be a fake 4k it has to be really 4k else Sony would be lying and with all those TV experts I don't think it wouldn't be possible for them to do real 4k on a smartphone.
The screen using the emulated 4k is razor sharp. By far sharper than any other phone I've used including the note 8. Are you sure your not just mistaking the overly unrealistic saturation of a amoled screen compared to a LCD one? I dont mean that in a sarcastic way, i genuinely dont see any comparison between the two. I havnt used the phone for any VR stuff though so can't comment on that

you are right but im not comparing only with samsung, also with HTC and the previous version of xperia , the Z3
yes maybe on emulated 4k it has sharper screen but keep in mind that on 1080 is not as sharp as other 1080p, even on 2k it isnt only on 4k mode it is unbeatable which to add is emulated and not native
put phone on 2k battery dies so much faster than lets say samsung or HTC which both have same CPU GPU and almost same battery size, how is that? because the resolution is emulated, which forces GPU to resize source resolution of 1080p to make it in a fake way look like 4k instead of showing native 4k (which doesnt require such hard work from GPU as its showing real pixels instead of emulating fake pixels!) Which leads to less over heating and less battery consumption.
heck even on 1080p screen looks worse and still get worse battery life than other phones...
thats what bothers

not exactly but some other phones have better 1080p than the 1080p on this device, yes text and symbols maybe just as sharp its hard to tell but im talking about pictures (for example, in instagram, facebook. youtube thumbnails etc...) I once was on 4k mode and it was very hard to tell the difference between this phone and the Z3 and even some times the z3 showed more picture details in instagram and its only 1080p...
im not complaining about the screen though, its pretty decent and with 4k mod on it looks superb, im just saying sony has put some thing in a device that is useless and im trying to figure out why...
by useless i mean sony left us no option to use such settings, why dont they add the options of 1080-120hz or 4k? naive and not emulated! this bugs me
and yes it is 4k, just like youtube you dont have to watch on 4k settings, but you can see the option is there which means it supports it.
that means even if you dont have a 4k video in your video app or album app, the option is there that means if you ever have a 4k video on there the device will play it at its maximum resolution.
phones that dont support 4k will show that the video looks as sharp as 1080 instead of real 4k
Hi. Just got a new HD10 specifically because I need the 1920x1200 resolution. But it is not currently functioning in that resolution, which is quite obvious by the fact that my stuff doesn't fit on the screen. Went to www.whatismyandroidversion.com and it shows the resolution is 1280x800. Checked wm size in ADB and it says 1920x1200. I have tried googling for a solution, but all I ever get is thousands of useless blogs listing the specifications. So hoping someone here knows what's going on.
How can I actually get the 1920x1200 resolution? Thx.

Do you want to see a native resolution of your Fire tablet?
You can use AIDA64 to view it:
Google Play: https://play.google.com/store/apps/details?id=com.finalwire.aida64
AIDA64 website: https://www.aida64.com/downloads/latesta64droid
know what the native resolution is, it is 1920x1200. But the browsers are only using 1280x800.
So I think this is happening because the device pixel ratio is 1.5. But I cannot figure out how to change this. There is no display scaling in settings, and it doesn't appear to be an ADB command either.
Got it. The pixel density in ADB was 240. 240 / 1.4 = 160. So wm density 160 brought the scale back to 1:1 and the browser is using the full resolution now.
