Imagine a laptop so light you could carry it in one hand, yet powerful enough to handle demanding tasks—meet the LG Gram SuperSlim. At just 990 g and only 10.9 mm thick, this ultra‑portable machine lets you stay productive wherever you go, without the bulk.
The SuperSlim’s magnesium chassis is engineered for strength and feather‑light feel. It passed seven rigorous US military tests, so you can trust it against drops, extreme temperatures, dust, and more. The 15.6‑inch OLED display delivers Full HD resolution, 100 % DCI‑P3 color, HDR 500, and a rapid 0.2 ms response, giving you crisp visuals and smooth motion for work and entertainment.
Powered by the Intel Evo platform and a Core Ultra 7 processor, the laptop offers up to 4.8 GHz turbo speed, 16 GB LPDDR5x memory, and a fast 1 TB SSD. The 60 Wh battery provides up to 20.5 hours of video playback, while Intel Unison lets you seamlessly integrate your smartphone, whether it runs Android or iOS.
Enjoy immersive sound with Dolby Atmos speakers, secure login via Windows Hello face recognition, and versatile connectivity with Thunderbolt 4, USB‑C Power Delivery, and Wi‑Fi 6E. All these features combine to create a reliable, high‑performance companion for your daily tasks.
