question about screen resolution

Jonyny — Wed, 20 Mar 2019 12:02:37 GMT

If I remember correctly, although all premium Xperias in past have 4K display, they display majority of contents in FHD (such as home screen etc) except for certain contents such as photo or video.

Does Xperia 1 do the same thing, or maybe instead of FHD+, it uses QHD+ like XZ3 or "all time 4K"?

Hi @Jonyny

Thanks for your question. Let´s see what i can find.

~~Ok so it's "cinemawide 4k" all the time.~~

~~The 4k resolution at that aspect is 3840 X 1644 (I believe)~~

~~This is also the resolution that 4k movies in 21:9 are presented in if taken from a crop of 16:9 a 3840x2160.~~

~~So for all intent and purposes, the screen is an always 4k at cinemawide 21:9~~

~~Hope that clears it up for you~~

Thanks for clarification, viridis.

So unlike old premium models which display most contents in FHD (again, like home screen, browser etc), Xperia 1 display them in 4K all the time.

I personally think it's quite a difference.

Could be big improvement in terms of visual but also could be bad for battey life.

I don't think the battery life will be hit by much at all tbh, I ran XZ2 premium in 4k for a week and it still easily got me through the day.

Plus, it's about 150 ppi more than the current 1440p xz3 at 18:9 so with the increased optimisation on power by Qualcomm, we're gonna see some nice improvements with no noticeable difference on power.

We are waiting for confirmation of Sony official staffs @Jonas @Martin

No the screen is 1080p unless displaying 4k video or photos.

I was then, unfortunately I took that info from a site that stated this but it, and subsequently I, was wrong.

I do believe that the resolution shown in your image (which should show up soon as I just accepted it) is the correct resolution for the UI and general use, with the resolution changing to 4k as with the previous "Premium" line of handsets

But, according to Gsmarena, it has always 4k displaying.

This is because @Viridis said Xperia 1 (Code name:Griffin) screen works in 4K all the time, which is a fake news

PsYCOW — Sat, 29 Jun 2019 02:05:33 GMT

Ok I actually am using the xperia 1 now j9110,

CPU-z and antutu benchmark states the screen resolution is 1096*2560

With 2,805,760 pixels.

FHD 1920*1080 is 2,073,600 pixels

QHD (4k) 3840*2160 is 8,294,400 pixels

What is going on?

Sony say the screen is 1644x3840 which is 6,312,960 pixels. Why is mine 3,507,200 pixels short?

Re: question about screen resolution

iArvee — Sun, 30 Jun 2019 15:27:48 GMT

The screen is in 1080p by default. Connect to the phone via adb and run wm size to get the default size.

@PsYCOW the resolution 1644x3840 is correct. It's 4k in 21:9 aspect ratio.

So to use in 4k I need to use pc to change it like my xz2 premium?

Does it even switch to 4k for related apps? I wouldn't know how to test it. Although I can watch YouTube videos in 4k but dunno if it's actually doing it or downscaling.

Re: question about screen resolution

Lord_viridis — Wed, 10 Jul 2019 09:52:23 GMT

It does indeed switch to 4k in related apps that support 4k

Re: question about screen resolution

iArvee — Thu, 11 Jul 2019 16:49:27 GMT

You'd need a kernel that supports native 4k. Wait on the sony dev channel to release that.

honorjames19 — Wed, 18 Mar 2020 20:42:35 GMT

I was just wondering how I can get 4k all the time thanks James.

Re: question about screen resolution

RottenFoxBreath — Wed, 18 Mar 2020 21:02:54 GMT

In a way you are already.

Whatever resolution upscaled to 4k as standard, and then when you watch 4k material, it's native 4k.

It really can't be much easier than that to explain, so I can't see how so many get their pants in a twist over it.

It's hardly rocket science.

I've been playing with the Game Recorder feature. At first, I was worried about; how do they solve for in-game sound, but I'm so shocked it's so good! Just by wearing Bluetooth earphones; it records the game sound clearly and perfectly.

Anyways to your question. I noticed that it records the game in 1440p HD (I don't know if I'm supposed to add a 'F' or 'R' to that), which is 2.5K resolution -vs- 2160p 4K.

Soooo..... I don't know if mobile games run at 4K, but wow, it records amazingly well in 1440p. My game recording tests:

Hokai Impact 3rd (CN Version): https://youtu.be/PNk4qUYYp6M
Dragon Raja: https://youtu.be/GayH5QJu1m4

Video Games, Web Browsing, Apps, etc Screenshots are 3840 x 1644, again at 2.5K.

Reading everyone's comments. Maybe we're all wrong. I think it's 1440p 2.5K all the time. It's defiantly not 1080p all the time. When does it switch to 4K? I don't know, probably "Upscaled to 4K." I would think the screenshot resolution would be different between apps. However, I debunk that idea, I can play a 4K YouTube, but the screenshot resolution stays the same. Which is probably a screenshot is limited to only 3840 x 1644.

The lingo they probably use is; 4K, 4K (secure), 4K (upscaled), 4K (upscaled, secure).

If you're really into 4K all the time, you want to look over at XDA Forums.

https://forum.xda-developers.com/xperia-c5-ultra/general/how-to-change-xperia-c5-ultra-screen-t3211909/

^ Taught me how to use ADB Shell.

ref: https://forum.xda-developers.com/xa-ultra/help/how-to-change-xperia-xa-ultra-screen-t3433583

You can ADB shell.

or the easier way in Developer mode, and alter your "Greatest Width," I think to 820 dp?

I use to alter all my 16:9 Xperia phones screen ratio with these methods. C5 Ultra, Z5 Premium, XZ2 Premium, XZ Premium, XA, XA2, etc...
