Chassis, connections, screen of the LG Gram 17Z90S-G.AA79F
With its thin and light Charcoal Grey magnesium design despite its large format, this versatile laptop is robust thanks to its compliance with the American military resistance standard MIL-STD-810H and has a discreet appearance.
The connectivity integrated into this multimedia-oriented Ultrabook is good, consisting of 2 USB-C Thunderbolt 4, Bluetooth 5.1 and Wi-Fi 6E ax wireless modules for communicating and connecting remotely, a useful HDMI video output for easily connecting it to a monitor or TV for example, an audio port but also 2 USB 3.0 (compatible with USB 2.0) guaranteeing transfers up to 10 times faster than USB 2.0 if you connect USB 3.0 peripherals to it.
You can authenticate biometrically using the fingerprint reader integrated into the power button and Windows Hello technology.
The chiclet keyboard can be backlit when you need to better discern your keys.
The screen will delight the most demanding in terms of colorimetric accuracy since it offers DCI-P3 colorimetry. Furthermore, thanks to its IPS technology, its viewing angles, both horizontal and vertical, are significant while its 16/10th format displays more information in height than the standard 16/9th.
The screen also stands out with its 2.5K definition, which is significantly higher than Full HD, well suited to High Definition content, while its anti-reflective coating provides better visibility than a glossy panel in a bright environment (e.g. outdoors).
Performance, autonomy of the LG Gram 17Z90S-G.AA79F
The LG Gram 17Z90S-G.AA79F targets those who want to acquire a high-performance large-format laptop that is nevertheless thin, light and portable, with a multimedia focus.
Nomads and others looking for a high-performance large format student laptop will be seduced since it is very thin and light for a 17-inch. Easy to carry, its autonomy is also around 9 hours on battery in light use.
However, this versatile Ultrabook relies on an Intel Core Ultra 7 155H processor with 16 hybrid cores, AI services and integrated Intel Arc graphics module to provide solid general performance that as many users as possible will appreciate.
This core deploys its full potential in areas that are intensive in CPU and RAM resources taking advantage of multi-cores and AI, such as photo editing or video editing. Under this type of work, we obtain much faster processing than with a classic Quad/Hexa Core and 8 GB DDR4/5.
Creative people will appreciate it, especially as the display is controlled by the Intel Arc graphics module with superior performance to the classic Iris Xe to calmly watch HD content such as photos and videos.
Playing light to modest games is also possible despite the lack of a dedicated graphics card. But only if you are willing to make concessions such as a reduction in the screen definition since in 2.5K more graphics calculations are necessary than in Full HD, which results in a lower number of fps.
The storage is of course entrusted to an SSD since it is more resistant to shocks than a hard drive, consumes less energy, is silent and much faster.
As a result, responsiveness and fluidity are much better on a daily basis with an SSD than with a hard drive.
So starting/stopping, launching software, carrying out processing or even accessing online game cards is faster with an SSD than with a hard drive.
As a bonus, the SSD integrated here offers a significant capacity of 1000 GB, allowing you to easily install and store quantities of software and files, including personal production.
As for heating and noise, they are very well controlled under this High Fidelity Ultrabook and therefore do not represent an obstacle to the purchase.
