Sony Xperia XZ Premium tutorial: Here's how to enable constant 4K display resolution

Pssst. Pssst! Got a Sony Xperia XZ Premium?

If so, then you're probably awed by its super-crisp 4K display... that's actually downscaling content to Full HD 1080p by default.

Yes, as per Sony, "4K (and 4K HDR with 4K HDR content) is used in the Album and Video apps and third party apps with 4K (and 4K HDR) content. Everything else, so homescreen, apps, menus, etc are shown in Full HD."

A bummer, isn't it? Having a 4K display on paper but not using it to its full potential... Well, lucky for all of you tinkerers out there, there's a neat little trick that allows you to easily force the Xperia XZ Premium to output 4K all the time. Of, course, this is likely to have a detrimental effect on your phone's battery life and performance, especially in games and other graphics-intensive tasks.

Sony Xperia XZ Premium - here's how to enable 4K output all the time

So, how do we know that the Xperia XZ Premium is not running at 4K all the time? First up, open up a system info app of your choice and check out the resolution. In our case, it's 1080x1920 pixels as per AIDA64, and we are fairly certain it will be the same in your case as well.

I don't know if they edited it but if you check "reference" below the tutorial slide, you'll see "@damirfranc".

But it's mentioned at the end of the article. Was it not there before?

youtubers damir franc and total tech do that and they see nothing significant difference in battery life if you enable the 4k content of xzp all the time.. total tech even got a good battery life for it.

Seeing as how this phone is a sub 6" LCD display, there is no reason for anything over 1080p save for a few situational circumstances. Pixel layout is of major importance, and this is where modern AMOLED tech does not match LCD.

I see no need to have everything constantly rendered at 4K. Battery life will be an absolute mess, not to mention overheating!

You will say that until the next note comes out with 4K display...... Technology should move forward, not stand still.

Total Tech has already debunked this theory. He was having 5+ hrs of sot with 21% left for the battery to die.

Great that you can do it but I have to ask why? Aside from multimedia and VR there is really no need for such resolution. I really wanted the concept to catch up when Sony started it with Z5P and other OEMs would start using the same thing. Sadly it didn't.

The Xperia XZ Premium's display isn't even 4K!
Sony claims it is 4K because it interpolates subpixels. But there are even less subpixels than in a Pentile display, actually...

might be just for a few niche market but when you do VR, the Sony 4K screen will give you less screen door effect compared to the LG one as you post in the link. The same could be said with Pentile AMOLED, but Samsung needs to bump up to 4K first before the lines start getting to disappear.
