Sony has been hanging on to the same Full HD 1080p screen resolution for many of its devices, including the original Xperia Z and the Sony Xperia Z3+. However, with the new Xperia Z4v, Sony featured a QHD resolution. But now, according to a new report, the Sony Xperia Z5+ will feature a 4K screen resolution, ahead of other OEMs.

User Agent profile pertaining to various models of the upcoming flagship Xperia Z5+ revealed that the variants include the model numbers Sony E6833, E6853 and E6883. The profile reveals that the upcoming Sony Xperia Z5+ will carry a 2160 x 3840 pixels screen resolution, according to Xperia Blog.

As far as the rumored Xperia Z5+ specifications go, the handset will reportedly come with a 5.5-inch+ display. In case the screen size turns out to be exactly 5.5-inch, packed with a 4K screen resolution, the pixel density will be 801 ppi.

The same User Agent profile also said that the Xperia Z5+ will be powered by a MSM8944 chipset, which is referred as Qualcomm Snapdragon 810 chip. It is worth reminding that, the S810 is the same chip that caused overheating problems in the past.

Meanwhile, Xperia Blog said that even if the S810 chipset, along with the Adreno 430 GPU, has the capacity to handle a 4K display, there is a good chance that it could affect the overall performance and battery life of the device. It remains to be seen if the enhanced display will indeed set the device back with regards to its performance.

On the other hand, GSM Arena said that Sharp introduced a 5.5-inch 4K LCD, with a release date slated for 2016. However, Sony, which is yet to confirm the Xperia Z5+ specifications, could be using other display suppliers to get the job done.
