Asus ZenPad S 8.0 Z580CA Review
25

Introduction
It’s been a while since we’ve last reviewed a dedicated tablet from Asus, seeing that the last one we got the chance to check out was the hybrid PadFone X mini from last year. Most companies nowadays tend to shy away from high-end tablets, especially on the Android side, but Asus comes back swinging with something delicious in the svelte ZenPad S 8.0. Now, there are variants of this particular model, but the one we’re dealing with here, the Z580CA, is the company’s flagship tablet that strives to balance work and play.
The package contains:
- Asus ZenPad S 8.0 Z580CA
- microUSB cable
- Wall charger
- Get start guide
- Important information
Design
Almost unbelievable we’re dealing with an 8-incher here, just because it looks and feels more like a 7-incher.
You’d hardly think we’re dealing with an 8-inch tablet here, just because it feels and looks more like a 7-incher thanks to how they’ve trimmed the footprint to achieve an impressive 74% screen-to-body ratio. What’s even better, is the fact that its design blends sophistication and elegance with its hairline patterned metallic chassis and a soft-touch leather accent that’s hugging one side of the tablet in the back. Even though it's still a bit wide to comfortably grasp with a single hand, its lightweight (298g) feel and svelte profile (6.6mm) do nicely in giving it some notable traits for a tablet of its caliber.
Unfortunately, the power button and volume controls lack any decent feedback when pressed – so you never know if you’ve actually pressed down on them or not. What’s really interesting, though, is the fact that it’s one of the few devices in the space right now with a USB Type-C connector, ensuring that it’s one step ahead of the game. And lastly, Asus blesses the ZenPad S 8.0 with dual front-firing Sonic Master speakers with DTS HD Premium Sound.

Display
We like its 2K resolution, but not so much with the other characteristics of the display.
Cementing its place as a premium tablet, the ZenPad S 8.0 is fashioned along with an 8-inch 1536 x 2048 (QXGA) IPS display with Corning Gorilla Glass 3 protecting it. Details, unsurprisingly, are plentiful factoring in its 8-inch real estate with its generous resolution – giving it a respectable pixel density of 320 ppi. As much as we take fancy over its sharpness, there’s just this subdued overall tone that lessens its attractiveness.
For one, its peak 387 nit luminance makes it troublesome to view outdoors when the sun is out, which can be the main contributing factor to its subdued appearance. Secondly, the display exhibits a colder tone with its ~7300K color temperature, giving colors a hint of blue. And while it’s technically not perfectl in hitting all the target values in the sRGB colorspace, it does nicely to stay within a certain degree of tolerance – though, the various shades of magenta tend to favor some bluish hues to them.

The CIE 1931 xy color gamut chart represents the set (area) of colors that a display can reproduce, with the sRGB colorspace (the highlighted triangle) serving as reference. The chart also provides a visual representation of a display's color accuracy. The small squares across the boundaries of the triangle are the reference points for the various colors, while the small dots are the actual measurements. Ideally, each dot should be positioned on top of its respective square. The 'x: CIE31' and 'y: CIE31' values in the table below the chart indicate the position of each measurement on the chart. 'Y' shows the luminance (in nits) of each measured color, while 'Target Y' is the desired luminance level for that color. Finally, 'ΔE 2000' is the Delta E value of the measured color. Delta E values of below 2 are ideal.

The Color accuracy chart gives an idea of how close a display's measured colors are to their referential values. The first line holds the measured (actual) colors, while the second line holds the reference (target) colors. The closer the actual colors are to the target ones, the better.

The Grayscale accuracy chart shows whether a display has a correct white balance (balance between red, green and blue) across different levels of grey (from dark to bright). The closer the Actual colors are to the Target ones, the better.
