Slim chances of this one, but if you haven't checked it out already, you shouldn't waste any more time and go check our Sony Xperia Z Ultra review. Certainly not without weaknesses, we are nevertheless impressed with Sony's foray into the phablet market. And while the Z Ultra's massive diagonal has become a recurring topic, the quality of the display is just as great and a topic of its own.
Best described as two thirds a tablet with just a third carrying the phone DNA, the Xperia Z Ultra's display has been largely improved in comparison with the panels in older Xperia smartphones. And though the advancement is noticeable even with a naked, untrained eye for the most part, some may be finding themselves scratching their heads, wondering exactly what has changed. Well, first and foremost, Sony's previously TV-exclusive Triluminos tech has made its way into the Z Ultra, allowing for a wider palette of colors for the software to pick from. This has been achieved through the use of the so called “quantum dots”, a set of super small nano particles that emit light at a preset wavelength, depending on which the human eye then perceives a given color. What's more, the so called OptiContrast technology that is present with the Z Ultra lets more backlight go through to the LCD TFT panel, resulting in higher brightness and contrast levels, along with the extra perk of better visibility outdoors.
But great hardware is only a part of the equation, and to that end, Sony's BRAVIA Engine 2 for mobile is working hard to improve certain aspects of local media content, such as contrast, saturation, noise reduction and sharpness. At this point, you're probably wondering what happened with the X-Reality engine (the successor to the mobile Bravia Engine 2), another previous TV-exclusive, so here are the bad news first: it's nowhere to be found – not on any version of the Z Ultra right now. The good news? An update is expected in the week commencing September 9 that will both add support for the new engine and a reworked UI.
That's about enough techno lingo, though. So head for the slideshow right below and witness for yourself the undeniable improvements Sony has packed into the Z Ultra through a visual comparison with the now older Sony Xperia Z.
