Chassis, connections, screen of the LG Gram 17 17Z90S-G.AD78F

Despite its large, very comfortable 17-inch format, it is thinner and lighter than a maximum of 15 and 16-inch models.
Ruggedized to meet the US military resistance standard MIL-STD-810H, this versatile laptop has a relatively understated look.

The connectivity integrated into this multimedia-oriented Ultrabook will delight demanding users because it includes 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 connect this laptop to a monitor or TV for example, 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 USB 3.0 devices are connected to it .

The screen will delight fans of High Definition and High Fidelity content thanks to its 2.5K definition superior to Full HD and its DCI-P3 colorimetry much more faithful than average.
Especially since its vertical and horizontal viewing angles are significant thanks to its IPS technology while its 16/10th format displays more information in height than the standard 16/9th.
Anti-reflective treatment, the screen also ensures better visibility than a glossy panel in a bright environment (e.g. outdoors).

Performance, battery life of the LG Gram 17 17Z90S-G.AD78F

The LG Gram 17 17Z90S-G.AD78F may be of interest to those who want to equip themselves with a thin and light, large format, high-performance, multimedia-oriented portable PC.

Despite its large, comfortable size, it is thin and light enough to be easily transported. It will delight nomads as well as some in search of a student laptop that it is able to last about 9 hours on battery in light use.

Despite these appreciable features, this laptop will satisfy a maximum of users since it provides solid overall performance.
It is in fact driven by an Intel Core Ultra 7 155H processor with 16 hybrid cores and AI performance, accompanied by a large amount of RAM of 32 GB, twice the average.

Creatives will particularly appreciate this core which deploys its maximum potential under CPU and RAM-intensive work taking advantage of multi-cores and AI, such as photo editing or video editing.
In these areas, we obtain much faster multimedia processing than with a classic Quad/Hexa Core and 8/16 GB DDR4/5.

Due to the thinness and lightness of the chassis, no dedicated graphics card is obviously included.
However, watching HD photos and videos is of course possible thanks to the benefits of the Intel Arc graphics solution inserted in the Core Ultra 7, superior to those of the classic Iris Xe.

You can even consider playing light to modest games thanks to the Intel Arc as long as you agree to some adjustments.
We are clearly thinking of a reduction in the screen definition since in 2.5K a greater number of graphic calculations are necessary than in Full HD which results in a lower number of fps.

The storage is up to par. It will delight demanding users since it includes a 1000 GB SSD, a large capacity for installing and storing quantities of applications and files including personal creations.

In practice, the SSD provides faster processing, startups/shutdowns and software launches than a hard drive, or even faster arrival on online game cards for example.

Generally speaking, the SSD guarantees much better fluidity and responsiveness on a daily basis than a hard drive because it is much faster, in addition to being silent, more energy efficient and more shock resistant.

Finally, expect heat and noise from this versatile multimedia Ultrabook when it is heavily used (e.g. processing).
To contain its temperatures, we can associate it with a ventilated support (remember to check the dimensions carefully!).
