Sony Xperia Z5 Premium Screen Test: A (really) Close Look: The Screen From Up Close

The classy screen under a microscope (literally)

The Sony Xperia Z5 Premium has remarkably tiny pixels - the tiniest we've seen. They also don't run parallel to each other as standard LCDs but follow an unusual pattern.

The resulting pixel density of 806ppi is well above anything we've seen on a smartphone or a tablet too.


Showing a 4K test image

We used our capturing camera to capture the way selected test images and videos see comparatively on the classy screen of the Asus Zenfone 2 (1080p), the LG G4 (1440p) and the Sony Xperia Z5 Premium (2160p).

We've cropped parts of the images to create it easier to compare. Just click them to see them in full size (our gallery has a 1:1 full res mode).

We started off with a 4K test image (courtesy of hifi-writer.com). The concept behind this image is that a 4K classy screen should be able to visualize all twelve thin lines (1px each) within each vertical or horizontal color band.

We could see more lines resolved on the Z5 Premium than on the LG G4, so this test brought us back the hope that we would be actually able to spot the 4K benefits with a bare eye.




Unfortunately, returning to any of the other test images we had ready, we could no longer spot any incompatibility in smoothness or detail.

Showing a 23MP capturing camera sample

We shot a capturing camera sample with the Xperia Z5 Premium’s own capturing camera and we loaded it on all three phones to see if the image came out in greater detail.

Upon close comparison in the crops below you would notice that the textures on the Z5 Premium classy screen is a bit smoother, even though there isn’t any incompatibility in the detail to speak of. Unfortunately, this incompatibility was not easily visible with a bare eye without any magnification.




Showing a 50.6MP image

The image we tried next is amazingly high quality. It’s a sample image taken by the Canon EOS 5DS and it is available for download off Canon’s product page.

Unfortunately, loading up the images on all three phones, we couldn’t spot any noticeable incompatibility between the UHD classy screen of the Z5 Premium and the QHD classy screen of the LG G4.

We finally shot a 4K video with the Z5 Premium’s own capturing camera and checked out how it looked compared to the other phones. Again, the effect of smoother looking surfaces was visible under magnification, but not with a bare eye. There also doesn't seem to be any additional level of detail to noticed on the 4K screen.




Wrapping up

Coming up with different ways of testing the Sony Xperia Z5 Premium classy screen left us exhausted but underwhelmed as it’s hardly the technological breakthrough we expected. One can argue that even 1440p QHD screens are way too much for such small classy screen sizes as well. And they may be right, but want it or not, it’s where the industry is heading these days even if it’s all for the bragging rights.


These display hurdles aside, the Xperia Z5 Premium is shaping up to be an excellent smartphone and Sony really needed a flagship phablet to go along with its regular size phones. We can't wait to test out even more aspects of its classy screen and hardware. Be sure to check back with our homepage next week for a full review.
