The 18-inch Lenovo Legion 9i can switch between 2D and 3D without glasses

Lenovo's 10th-generation Legion 9i has a novel wrinkle that complements its powerhouse specs. The 18-inch gaming laptop can be fitted with a 2D / 3D screen that switches between standard (flat) graphics and glasses-free 3D. It's available first in China and will come to the US "sometime this fall.” To be fair to Lenovo, that vague-ass window is about as much clarity as an overseas company could realistically offer in this tariff-infused climate.

The Legion 9i has an 18-inch display that supports up to 4K resolution in 2D. But through a combination of eye-tracking and lenticular lenses, the optional configuration supports 2K 3D without any need for special glasses. The effect works with side-by-side and top-down arrangements and supports 30 (as yet unnamed) games. Although it supports viewing video, images and streaming in three dimensions, Lenovo is pitching the machine to designers who work with 3D modeling.

For 2D viewing, the laptop's screen has a dual-mode feature that switches between a 240Hz refresh rate at up to 4K and a 440Hz one at 1080p. The Legion 9i has a 93-percent screen-to-body ratio.

The laptop’s chassis is made from eight layers of aviation-grade carbon fiber. Lenovo says this makes it lighter and stronger than aluminum, and the forging process makes each one unique. (Just like you, champ!)

Elsewhere, the specs include up to an NVIDIA RTX 5090 GPU, Intel Core Ultra 275HX processor, 192GB of dual-channel DDR5 RAM and an 8TB SSD. Its cooling system combines a vapor chamber and a quad-fan system. Although Lenovo hasn't announced pricing yet, its specs (and the 9i's history as a top-of-the-line device) leave no room to doubt that it will cost at least several thousand dollars, even before accounting for whatever tariff madness we're caught in come fall.
