Anonymous, 25 Feb 2019What about WQHD+ phones such as GalaxyS10 & LG G8; everyone says they have 2k display whil... morethe term 2K does underrate the screen of Galaxy devices like the Galaxy Note 9, since 2K means 2048 x 1080, while the device got a 2960 x 1440 screen. Thats also why virtually nobody is refering to the screen as 2k, instead they say its Quad HD plus.
The Note 9 screen is 3K. However, this term is not very popular.

I am no expert on this but my point is that clearly this is a 4K smartphone since 4K means roughly 4000 pixels on the horizontal side in landscape mode (which it has with 3840) and Sony is advertising this phone as 4K HDR and obviously they know what they are talking about

16:9 3840 x 2160 = 4K
21:9 3840 x 1644 = 4K
21: 9 5040 x 2160 = would be 5K
MASTERY, 25 Feb 2019For those of you who don't know how to compare resolution with aspect ratios (which I can see ... moreYes indeed. Xperia Premium series are still the kings in term of pixel density (ppi). Xpeia1 can't beat my old Z5premium in resolution battle!
MASTERY, 25 Feb 2019For those of you who don't know how to compare resolution with aspect ratios (which I can see ... moreWrong.
4K 16:9 is 3840 x 2160 pixels
4K 21:9 is 3840 x 1644 pixels
4K means that there are horizontal approximately 4000 pixels (3840), while viewing the Smartphone on landscape mode.
So yes, while it is a 1644p Screen, the Xperia 1 indeed the worlds first 4K HDR OLED Smartphone.
For those of you who don't know how to compare resolution with aspect ratios (which I can see there are a lot of), allow me to clarify. 4K is 2160p, that's ingnoring aspect ratios. 4K on a display with a 4:3 aspect ratio is 2160x2880 (4/3 = 1.333… x 2160 = 2880).
4K on 16:9 display: 2160x3840
4K on 18:9 display: 2160x4320
4K on 21:9 display: 2160x5040
Notice how increasing the aspect ratio (length) increases the amount of pixels, this is so when you're viewing a 16:9 4K image on a 21:9 4K display, it will use the same amount of pixels to generate the picture, thus there will be no loss in quality. Another important note is although increasing the aspect ratio increases the amount of pixels, the pixel density remains the same.
The Xperia 1 has a 21:9 aspect ratio with a resolution of 1644x3840 (21/9 = 2.333… x 1644 = 3836, which Sony rounded to 3840). This indicates that the Xperia 1 has a 1644p display, which is slightly higher than 1440p. Sure when you're watching media it may have an option to upscale to 2160p, but in reality, you'll be viewing it at 1644p.
Therefore the Xperia 1 has a 1644p display not 2160p (4K).
Screen too long chin bezels in bottom and top and a small battery for a power demanding phone
Here is what I don't like: Honestly I am disappointed about the size of this device. I mean it is as big as your head, and if somebody is short and wear smaller clothes they can not comfortably put this in their pockets. Do not get me wrong, I respect Sony, I have used Xperia Sony, I respect Japan, but I can not agree with their vision this time. The phone looks too long, it looks weird.
The battery is a joke, come on, Samsung and others have much bigger batteries.
What I like is the triple camera system, I am sure it will rock! Sony has become strong when it comes to the camera. What I also like is their screen. The XZ3(which looks much much better), has even better display than the Note 9.
Overall it is a so-so device(at least for me). Everybody has its preferences you know.
Anyway, next time Sony please make a smaller version of your flagship, if you want more sales. Thank you, and keep up the good job!
joe nodden, 25 Feb 2019Lol that display ain't 4k.Why would you want 4k screen on a tiny screen?! I bet you still miss detail texture on a 4k smartphone o_O.
joe nodden, 25 Feb 2019Lol that display ain't 4k.by definition, yes it is 4k
joe nodden, 25 Feb 2019Lol that display ain't 4k.It's 4k pixel density.
Anonymous, 25 Feb 2019I don't know how did they say Xperia 1 has 4k display because it hasn't! 4K means 4 times more... moreAlthough I agree with your point of view, in reality at 21:9 UltraWide Cinema aspect ratio monitors and TVs, the official numbers for the respective resolution is as it follows:
UltraWide-HD > 2560x1080
UltraWide-UHD (2K) > 3440x1440
UltraWide-4K > 3840x1600
UltraWide-5K > 5120x2160
UltraWide-10K > 10240x4320
It probably has to do with the exact pixel count on each resolution thus despite the fact that 3840x1600 gives us less than 8mil pixels (6.31mil on Xperia 1) that 4k is supposed to be, the resolution of 5120x2160 gives us more than 11mil pixels which also is more than 4K. So a middle ground had to be made to define 4K in Cinema/Ultra Wide 21:9 panels.
joe nodden, 25 Feb 2019Lol that display ain't 4k.That is 4k. 1920+1920 is 3880 then they rounded it to 4000 to be termed 4k
Sony plan to release this phone in May. By that time people will already lose interest and I bet more new phones will be out in the market.
