Certified to the American military robustness standard MIL-STD-810H, this thin and light black versatile laptop in a comfortable format has a resolutely discreet appearance.
This laptop PC has good connectivity consisting of 2 USB-C Thunderbolt 4, a useful HDMI video output for easily connecting it to a monitor or TV for example, Bluetooth 5.1 and Wi-Fi 6E wireless modules. ax to communicate and connect remotely, an audio port without forgetting 2 USB 3.0 (USB 2.0 compatible) guaranteeing transfers up to 10 times faster than USB 2.0 when USB 3.0 devices are included connected.
Biometric authentication is made possible with this Ultrabook since its webcam adopts the Infrared functionality allowing facial recognition, in particular via Windows Hello technology.
The chiclet keyboard can obviously be backlit whenever you need to better discern its keys.
Those looking for a High Fidelity High Definition screen such as creatives will appreciate the 2.5K definition higher than Full HD of the screen with DCI-P3 colorimetry much more faithful than average.
Its 16/10th format displays more height information than the classic 16/9th while its IPS technology gives it significant viewing angles, both horizontally and vertically.
Thanks to its anti-reflective coating, the screen is also more readable than a shiny panel in a bright environment (e.g. outdoors).
Performance, autonomy of the LG Gram 16 16Z90S-G.AD78F
The LG Gram 16 16Z90S-G.AD78F is a versatile multimedia-oriented laptop, thin and light, portable despite its comfortable format offering recent components.
Nomads like some wishing to equip themselves with a 16-inch student laptop will be delighted because in addition to being thinner and lighter than many smaller-format Ultrabooks, it is able to last around 10 hours on battery. in light use.
Despite this great autonomy, solid performance here is not sacrificed and will satisfy a maximum of users, especially creators.
Because this Ultrabook is built around an Intel Core Ultra 7 155H Meteor Lake processor with 16 hybrid cores, AI services and integrated Intel Arc graphics module, supported by a large amount of 32 GB RAM, or twice more than the average .
This duo deploys its 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, where we obtain much faster processing than if we were dealing with a classic Quad/Hexa Core processor accompanied by 8/16 GB DDR4/5.
This core is well supported in multimedia and more generally in everyday life by SSD storage.
Because an SSD provides much better fluidity and responsiveness thanks to its greater speed, its silent operation, its lower energy consumption and its greater resistance to shocks.
As a bonus, the SSD here offers a significant capacity of 1000 GB to accommodate quantities of software and files, including personal creations.
Compared to a hard drive, an SSD ensures faster starts/stops, processing and launches of applications, or even faster arrival on online game cards.
Please note, however, that this laptop is not aimed at gamers because it does not include a dedicated graphics card.
However, thanks to the Intel Arc we can play light to modest games if we are ready to make concessions. We are clearly thinking of a reduction in screen definition since 2.5K requires more graphics calculations than Full HD, which results in a lower number of fps.
Obviously thanks to the Intel Arc, whose performance is superior to that of the Iris Xe, we can watch HD photos and videos.
Finally, this versatile multimedia Ultrabook heats up and makes itself heard when pushed hard (e.g. treatments).
To limit its temperatures, it can be combined with a ventilated support if necessary (remember to check the dimensions carefully!).
