THE TL;DW
- Unbox Therapy puts the new LG Gram lineup through its paces, spotlighting the 17Z90UR as the lightest 17-inch RTX laptop on the market.
- The featured Gram Pro 17 packs an RTX 5050 GPU alongside LG’s “Aerominum” chassis, aiming to combine gaming-grade graphics with ultra-portable weight.
- LG also expands the range with the 16Z90U and 17Z90UB models, giving buyers OLED and productivity-focused options alongside the gaming-leaning Pro variant.
The Jupiter Take
This is a branded partnership video, so treat LG’s “world’s lightest” framing as a manufacturer marketing claim rather than independent lab verification. Still, cramming an RTX 5050 into a sub-1.4kg 17-inch chassis is a genuine engineering trade-off worth seeing tested hands-on by a creator with Unbox Therapy’s reach.
Context
LG unveiled the 2026 Gram lineup at CES, built around a new “Aerominum” chassis material designed to cut weight while adding durability. The flagship 17Z90UR pairs a 17-inch WQXGA display with an Nvidia RTX 5050 GPU, and LG has marketed it as the lightest 17-inch RTX laptop currently available. JupiterFeed previously covered this same model when LG first announced it, in a post on the world’s lightest 17-inch RTX laptop.
