Dynabook Portégé X40-G in Review: Luxury business notebook offers display protection against unwanted glances

Recycling. Dynabook's slim 14-inch model features a nimble NVMe SSD, a Core i5 processor and two Thunderbolt 3 slots. The display has a switchable protection against side views.

Case, equipment and input devices

Dynabook relies on a slim, dark blue metal case with matt-blunt surfaces, which was adopted from the Toshiba Tecra X40-E. The device does not show any manufacturing flaws. While the stiffness of the base unit is pleasing, the lid should have a bit more of it. The battery is firmly installed. You can reach the innards after disassembling the lower shell.

The notebook has a USB 3.2 Gen 1 port (Type A USB) and two Thunderbolt 3 slots (Type C USB) on board. The latter support Displayport-per-USB-C andPower Delivery. The X40is powered by the included Type-C-USB power supply.The computer does not havea proprietarypower supply connector. The built-in MicroSD memory card reader is one of the slowest of its kind.

The WLAN chip (Intel Wi-Fi 6 AX201) supports the standards 802.11 a/b/g/n/ac/ax and provides Bluetooth 5 functionality. The data rates determined under optimal conditions (no other WLAN devices in the vicinity, short distance between notebook and server PC; router: Netgear Nighthawk AX12) turn out very good.

The illuminated chiclet keyboard has proven to be suitable for everyday use, and the keystrokes for the second and third functions have been criticized. These are kept in a grey tone and are generally difficult to recognize. They are also not illuminated. A multi-touch capable click pad (approx. 9.9 x 5.7 cm) and a trackpoint including two mouse buttons serve as mouse replacement.

Display

Pixel Grid
Pixel Grid

While the matte, viewing angle-stable 14-inch screen (IPS, FHD) delivers a good brightness value (371.6 cd/m²), the contrast (927:1) is too low. We consider values beyond 1,000:1 to be good. The display flickers at brightness levels of 20 percent and below with a frequency of 24,000 Hz.

The screen already shows good color representation in the as-delivered condition. With a color deviation of about 2.7, the target (Delta E less than 3) is met. It does not suffer from a blue cast. On the color space representation side, the display performs relatively well with coverage rates of 62% (AdobeRGB) and 96% (sRGB).

The display offers a switchable protection ("Fn" + "D") against side views. There is a difference between the two states, the wisdom of last resort does not represent the function. Screen contents are still visible from the side.

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
26 ms ... rise ↗ and fall ↘ combined↗ 14 ms rise
↘ 12 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. » 48 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (24.4 ms).
       Response Time 50% Grey to 80% Grey
39 ms ... rise ↗ and fall ↘ combined↗ 21 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 0.8 (minimum) to 636 (maximum) ms. » 43 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (38.7 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 24000 Hz ≤ 20 % brightness setting

The display backlight flickers at 24000 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 24000 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 9725 (minimum: 5 - maximum: 142900) Hz was measured.

Performance, emissions and battery life

The built-in Core i5-10210U processor (4 CPU cores, 8 threads; UHD Graphics 620 GPU) offers sufficient performance for office and internet applications. The CPU can use its turbo permanently at medium level. The Portégé was not created for displaying games. The hardware can only handle a few modest titles.

The system drive is an NVMe-SSD (M.2-2280) from Samsung, which provides 256 GB of storage space. The transfer rates of the SSD turn out very good, and replacing the SSD would require the complete removal of the motherboard. The SSD is located on the inward facing side of the motherboard.

When idle and under low load, the laptop's fan often stops. Under load it sometimes turns up too much: A sound pressure level maximum of 46.2 dB(A) should not occur with a simple office device. The SSD occasionally emits an audible whimper/squeak - for example during the DiskSpeed benchmark. The notebook does not heat up excessively over the entire load range. The stereo speakers produce an acceptable sound that lacks bass.

There are no conspicuous features regarding the energy consumption. In the WLAN test (simulates by means of a script the load when calling web pages, display brightness about 150 cd/m²) the computer reaches a runtime of almost 8 hours - a quite good, but not an outstanding value. A 14-incher of the price level presented here must deliver more. The competitors achieve better endurance values thanks to larger capacity batteries.

Verdict

The Portégé X40-G is one of the business notebooks of the upper class. Accordingly, Dynabook lets the device be princely paid: Just under 1,600 Euros have to be paid for the 14-inch notebook. The computer's design is no longer as fresh as it used to be, but the relatively wide display frame makes it look a bit old-fashioned.

The metal casing and the low weight suggest a very durable notebook. With a WLAN runtime of just under 8 hours, this is only partly the case. Here the competition offers more.

A high purchase price goes hand in hand with a meagre equipment level. In terms of price, you would expect more RAM, dual-channel mode memory, more storage space, a larger-capacity battery, a higher-contrast screen - and perhaps an LTE modem.

Core i5 processor, 8 GB of memory (1x 8 GB, single channel mode, max. 32 GB) and 256 GB NVMe SSD should be sufficient for the expected usage scenarios. While the memory could still be easily expanded, replacing the SSD would not be easy. This requires the complete removal of the motherboard.

The matte screen (FHD, IPS) has made a positive impression to a large extent, but should offer a higher contrast. The switchable privacy screen is more a gimmick than really useful. Thanks to two Thunderbolt 3 connectors (display port via USB-C, Power Delivery) the power supply and an additional device (docking station, external GPU) can be plugged in at the same time.
