Our opinion on the LG Gram 17Z90S-G.AD7BF
Thin and light despite its large, comfortable 17-inch format, the versatile laptop PC LG Gram 17 17Z90S-G.AA78F nomad with a battery life of 9 hours suitable for students, benefits from a High Definition High Fidelity 2.5K DCI-P3 IPS 16/10 screen and fast SSD storage with a large capacity of 2 TB which reinforces its responsiveness. The latter accelerates multimedia processing like the large amount of 32 GB RAM and the Intel Core Ultra 7 155H hybrid Meteor Lake processor with high-performance Intel Arc graphics solution suitable for modest games. This discreet, creative-oriented black Windows 11 Ultrabook is also equipped with a backlit keyboard, an Infrared webcam for facial biometric authentication as well as connectivity including 2 USB 4 Type-C Thunderbolt 4 and Wi-Fi 6E.

The LG Gram 17Z90S-G.AD7BF faces the competition
The LG Gram 17Z90S-G.AD7BF is currently displayed in promotion at the house of Amazon, Baker and the Fnac. It is positioned as one of the cheapest and lightest in its category to offer such a large amount of RAM and SSD storage capacity with such a high-performance processor and graphics solution in such a large format (17 inches) with a screen with such high definition and faithful colors as well as Thunderbolt 4 connectivity.

Chassis, connections, screen of the LG Gram 17Z90S-G.AD7BF
It has a resolutely sober appearance with its thin and light black design despite its large format, robust thanks to its certification to the American military resistance standard MIL-STD-810H.
This versatile multimedia laptop suitable for creating integrates good connectivity consisting of 2 USB-C Thunderbolt 4, an HDMI video output useful if you plan to connect it to a monitor or a TV for example, wireless modules Bluetooth 5.1 and Wi-Fi 6E ax to communicate and connect remotely, an audio port but also 2 USB 3.0 (USB 2.0 compatible) providing transfers up to 10 times faster than USB 2.0 if the USB 3.0 devices are connected to it.
Authenticating biometrically is possible with this Ultrabook because its webcam is equipped with Infrared technology allowing facial recognition, in particular via Windows Hello.
The chiclet keyboard has a backlighting solution that you simply activate when you need to better distinguish your keys.
To appeal to creatives, the screen adopts IPS DCI-P3 specifications thanks to which its viewing angles, both horizontal and vertical, are significant and its colorimetry is more faithful than average.
Especially since the screen also displays a 2.5K definition superior to Full HD associated with a 16/10th format which is more comfortable in height than the classic 16/9th.
Anti-reflective treated, the screen also offers better visibility than a shiny panel in a bright environment (e.g. outdoors).
Performance, autonomy of the LG Gram 17Z90S-G.AD7BF
The LG Gram 17 17Z90S-G.AA78F may appeal to those who wish to invest in a thin and light nomadic large-format high-performance multimedia-oriented laptop PC offering large storage capacity.
Despite its large 17-inch format, which is not the most nomadic by nature, it is easy to transport thanks to its lightness and finesse. It will be of even more interest to nomads as its battery life is around 9 hours in light use, enough to interest some wishing to equip themselves with a student laptop.
Those looking for a large SSD storage capacity will be delighted that this laptop offers 2000 GB, i.e. twice more than the average to accommodate many software and files including personal production.
As a reminder, the advantages provided by an SSD are undeniable compared to a hard drive: greater shock resistance, silent operation, lower energy consumption or even greater speed.
The latter implies much better fluidity and responsiveness on a daily basis with an SSD than with a hard drive.
This translates in particular to faster starts/stops, processing and launches of applications or even faster arrival on online game cards.
Although it does not include a dedicated graphics card and therefore clearly does not target demanding gamers, this laptop PC allows you to view HD photos and videos thanks to the Intel Arc graphics module housed in the processor.
And if one is willing to compromise, playing light to modest games is even possible with the Intel Arc. Clearly reducing the screen definition is advisable because a greater number of graphics calculations are necessary in 2.5K than in Full HD, which results in a lower number of fps.
The Intel Arc takes place within the Core Ultra 7 155H, Meteor Lake processor with 16 hybrid cores and AI services. It is supported here by a large amount of above-average 32 GB RAM.
These components deliver solid general performance capable of satisfying a maximum of users. Their full capabilities are especially noticeable under CPU and RAM-intensive jobs leveraging multi-core and AI. This is for example the case in video editing or photo editing, areas in which we obtain faster processing than with a classic Quad/Hexa Core and 8/16 GB DDR4/5.
Finally, expect heat and noise from this versatile multimedia Ultrabook when it is pushed hard (e.g. games, processing).
If necessary, it can be coupled with a ventilated support to limit temperatures (remember to check the dimensions carefully!).
