Ematic EWT117 (Atom x5-Z8350) Convertible Review

Good display, but far too slow. The 11.6-inch Ematic offers a lot on paper, but it doesn't have the speed to keep up with even the most simplest of tasks like browsing, 1080p streaming, or even word processing. You're better off investing that $200 elsewhere.

Los Angeles-based company Ematic specializes in inexpensive tablets, laptops, accessories, speakers, and even drones. One of these products is the 11.6-inch EWT117 convertible netbook equipped with the Cherry Trail Atom x5-Z8350 SoC. At under $200 retail, the 2-in-1 system sounds rather compelling especially because it offers a full-HD 1080p IPS touchscreen instead of HD 720p as found on most other netbooks. The EWT117 competes directly with other inexpensive subnotebooks including the Asus E203, Trekstor Yourbook C11B, Lenovo Ideapad 120s, Lenovo Flex 11, and the Acer Spin 1.

As our measurements below will show, however, the netbook leaves subpar impressions even for its price range.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
29.6 ms ... rise ↗ and fall ↘ combined↗ 18.4 ms rise
↘ 11.2 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 72 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25 ms).
       Response Time 50% Grey to 80% Grey
38.4 ms ... rise ↗ and fall ↘ combined↗ 19.6 ms rise
↘ 18.8 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 40 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (39.8 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 500 Hz ≤ 25 % brightness setting

The display backlight flickers at 500 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 25 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 500 Hz is relatively high, so most users sensitive to PWM should not notice any flickering. However, there are reports that some users are still sensitive to PWM at 500 Hz and above, so be aware.

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9367 (minimum: 43 - maximum: 142900) Hz was measured.

Verdict

In review: Ematic EWT117BL. Test model provided by Ematic
In review: Ematic EWT117BL. Test model provided by Ematic

The Ematic EWT117 is a classic example of promising too much for too little money. A fully functional Windows 10 convertible laptop with a MicroSD reader, HDMI port, and 1080p IPS touchscreen for under $180 USD is still too good to be true without heavy drawbacks. In this case, the system is extraordinarily slow due to both its Atom CPU and very poor SSD performance. Even simple actions like word processing or video playback - which the Ematic is supposed to excel at - move at a snail's pace.

Our unit exhibited some hardware issues as well. The trackpad would frequently cause the mouse cursor to jump unexpectedly and our MicroSD card would sometimes become stuck in the spring-loaded MicroSD reader.

The best aspect of the Ematic is its 1080p IPS touchscreen which covers a surprisingly wide range of colors (95 percent sRGB) considering the price. Unfortunately, this means little since the rest of the system is subpar.

We're not asking for very much from a $200 touchscreen netbook. However, when even a budget $200 Android tablet can browse, type, and play videos faster than the Ematic, then it becomes difficult to recommend the EWT117 to most home users.

Allen Ngo - US Editor in Chief
After graduating with a B.S. in environmental hydrodynamics from the University of California, I studied reactor physics to become licensed by the U.S. NRC to operate nuclear reactors. There's a striking level of appreciation you gain for everyday consumer electronics after working with modern nuclear reactivity systems astonishingly powered by computers from the 80s. When I'm not managing day-to-day activities and US review articles on Notebookcheck, you can catch me following the eSports scene and the latest gaming news.
