The Asus Vivobook Pro 14 Oled consists of an aluminum cover with an embossed Vivobook badge. The rest of the PC is entirely made of plastic, from the chassis to the keyboard piano. Only the screen border is black with a matte effect that contrasts with the shine of the Oled panel.
When opened, the backlit keyboard reveals its gray keys on a gray background. An aesthetic choice, but which makes the keys unreadable with the white backlighting during the day. The highest level of the backlight, however, allows this phenomenon to be reduced. The touch offered by the keyboard lacks rigidity at the end of the race. In addition, the center of the latter sinks slightly, accentuating this feeling. The lack of a fingerprint reader to quickly unlock the PC is problematic because, as we will see, the webcam is not Windows Hello compatible.
The touchpad is relatively wide (13 cm) for a 14-inch chassis. All Windows 10 gestures are well taken into account and dragging and dropping a tap in the center of the pad is easy. Asus has added the NumpPad function which allows you to display the numeric keypad on top of it. A long press in the upper right corner brings it up, while a long press in the upper left corner changes its brightness.
The connection consists of two USB 2.0 ports on the left edge and a USB-C 3.2 port, a Thunderbolt 4 port, an HDMI 1.4, a microSD port and a headphone jack on the right side of the PC. For network connectivity, Asus uses an Intel AX201 chip offering wifi 6 at 2400 Mb/s and Bluetooth 5.2.
The HD webcam has a mechanical cover, but lacks the Windows Hello unlock feature. The image quality is just acceptable.
Cooling is provided by two fans and two heat pipes. Our test version (Vivobook Pro 14 Oled S3400PA) not having a dedicated graphics card, the Intel Core i5-11300H is particularly well cooled. This is confirmed on thermal imaging. Thus, after more than 15 min of encoding, we noted less than 40°C at the level of the air vents on the screen. The keyboard stays relatively cool with a 35°C hot spot noted to the right of the space bar.
Noise pollution is also contained since the Vivobook Pro 14 Oled stabilizes at 37.1 dB. A decent sound level is reached after several tens of minutes of use. A slight hiss will be audible in open space by your neighbors.
Component access is achieved with the removal of nine Torx screws. The shell unclips easily, but don’t expect to expand the amount of RAM. Indeed, Asus has chosen LPDDR4 type RAM, therefore welded. Only the battery, the SSD and the wifi card are accessible and removable.
The Asus Vivobook Pro 14 Oled bears the reference S3400PA-KM0021T. It is equipped with an Intel Core i5-11300H processor with four hyperthreaded cores and can reach a boost frequency of 4.4 GHz with 35 W of TDP. In practice, the Core i5-11300H stabilizes at 3.58 GHz on multithreaded encoding. Asus boasts a 45 W mode that can be activated in the MyAsus software; however, we did not notice any significant gain with this High Performance mode. Finally, 8 GB of RAM and a 512 GB Intel 660P SSD complete our configuration.
The Vivobook Pro 14 Oled’s Core i5-11300H gets an index of 82, which puts it between the AMD Ryzen 5 5500U of the Zenbook 13 Oled from the same manufacturer and the Intel Core i7-1165G7 of the HP Envy 14.
In use, the processor that “motorizes” the Vivobook will allow you to do occasional video editing and photo editing. However, the presence of a graphics card would be more than desirable to shorten the processing time of creative software.
In game, the 80 calculation units of the Iris Xe graphics part are not really comfortable. In Diablo 3 in Full HD and all the settings at maximum, we obtain a small 28 fps on average, making the game just passable.
The 512 GB Intel 660p SSD is close to 3 GB / s in reading and just over 1600 MB / s in reading. Being equipped with QLC chips, it sees its speeds drop to around 110 MB/s once the cache capacity has been reached. Little impact in everyday life, but if you handle very large files such as video rushes, the bit rates will be strongly impacted.
The Asus Vivobook Pro 14 Oled has an Oled panel in 16:10 format displaying 2880 x 1800 px at 90 Hz. It is also HDR compatible with peak brightness of up to 600 cd / m². According to our calculations, it occupies 79% of the surface of the PC. The side borders are 8 mm and close to a centimeter for the upper part.
Under our probe, the Oled panel calibrated by Asus is close to perfection. The delta E is 2, the colorimetric drifts are therefore imperceptible to the naked eye (i.e. less than 3). The temperature is also particularly well controlled with 6522 K recorded for an ideal value of 6500 K.
Brightness is limited to 396 cd/m² and can reach 621 cd/m² in HDR mode. The reflectance (percentage of reflected light) is 46%. This remains in the average of glossy panels, but an anti-reflective treatment could have reduced this reflectance below 30% in order to make its use more pleasant near a window.
Nothing to complain about the contrast and the response time, the Oled panel providing by definition almost perfect blacks and therefore an almost infinite contrast ratio, just like the response time, well below a millisecond.
