Chinese Tech Laptop / Notebook Convertible / 2-in-1 Touchscreen Windows

4K上网本 PhilBook Max是一款14.1英寸翻转本,价格略高于400欧元。 设备很好,但不幸的是,制造商XIDU选择了低亮度触摸屏和低性能的赛扬处理器。

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
28.8 ms ... rise ↗ and fall ↘ combined↗ 16.4 ms rise
↘ 12.4 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. » 66 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.9 ms).
       Response Time 50% Grey to 80% Grey
38.4 ms ... rise ↗ and fall ↘ combined↗ 20.4 ms rise
↘ 18 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 (39.5 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 25000 Hz ≤ 20 % brightness setting

The display backlight flickers at 25000 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 20 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 25000 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 13573 (minimum: 43 - maximum: 2500000) Hz was measured.

In review: XIDU PhilBook Max. Test device provided by XIDU.

The XIDU PhilBook Max is currently available for around 400 euros. It comes with a 14.1 inch convertible with a neat case, practical input devices and the most important interfaces. But the two big weaknesses are the display and the performance. Although it is an IPS screen with an actually decent picture impression, the brightness is very low. Together with the reflective screen surface, it is hardly possible to use it in bright rooms or even outdoors.

It is also important to be clear when it comes to performance that the planned tasks must not be too demanding. When updating or installing, the device is fully loaded, so you can forget about multitasking. 

Low performance and dark display: The PhilBook Max offers some positive features, but performance is often the limiting factor. Here the competition simply offers more.

The price is still too high in our opinion, at just over 400 Euros. Especially from Chuwi there are better offers in this segment or even for less money.
