AI Laptop with Dual Touchscreens

The LG Gram 17Z90TL pairs an Ultra 9-288V processor with 32GB LPDDR5X memory and a 2TB PCIe SSD. A 17.0-inch 2560x1600 touchscreen and the included 14-inch Duex Max DS monitor create a portable dual-display workspace. Windows 11 Pro runs on 802.11be Wi-Fi and Bluetooth 5.4 connectivity.

Upgrade from Single-Screen Ultrabooks

This configuration replaces a standard clamshell laptop when mobile multitasking demands two independent panels. The jump is worth it for professionals who edit timelines, code, or reference documents side-by-side without an external dock. Buyers who need discrete graphics or upgradeable memory should look elsewhere.

Ready to Use with One Cable

The Duex Max DS monitor draws power and video through a single Thunderbolt 4 connection, so no extra adapter is required. OnBoard LPDDR5X cannot be expanded later, and the 65W Type-C supply limits sustained peak performance. Fingerprint login and the backlit keyboard work immediately out of the box.

Questions about this item

What are the laptop's dimensions and weight for fitting in a bag?

The laptop measures 15 inches wide by 10.25 inches deep by 0.9 inches high and weighs 3.1 lb.

How is the Duex Max DS monitor connected and what step is often missed?

Connect the monitor via one of the two Thunderbolt 4 ports; the step often missed is installing the Mobile Pixels driver so the second screen is recognised.

What maintenance will the 78 WHr battery need later?

The 4-cell 78 WHr battery is internal; when runtime drops noticeably, a qualified technician must replace the pack.
