17.0-inch AI laptop with secondary monitor

The LG Gram 17Z90TL-H.AUB8U3 pairs a 17.0-inch touchscreen IPS panel at 2560x1600 with an Intel Ultra 9-288V processor reaching 5.1 GHz. Thirty-two gigabytes of LPDDR5X memory and a 1TB PCIe NVMe SSD support multi-tasking workloads. Windows 11 Home runs on the 15th-generation platform. The bundle adds a Mobile Pixels Duex Max DS 14-inch FHD monitor for extended screen space.

Vapor-chamber cooling with dual fans

A vapor-chamber thermal module and dual fans dissipate heat from the 8-core CPU and Arc 140V integrated graphics during sustained loads. The 65W USB-C power adapter charges the 4-cell 78 WHr battery through the Type-C port. Fan noise stays low during typical productivity tasks. The chassis weighs 3.1 lb and measures 0.9 inch thin.

Duex Max DS adds portable dual-screen workflow

The included 14-inch FHD secondary display connects via a single cable to provide a dual-monitor setup without extra power bricks. Two Thunderbolt 4 ports deliver video, data and charging simultaneously alongside a headphone-microphone combo jack. Wi-Fi 802.11be and Bluetooth 5.4 handle wireless peripherals. A fingerprint reader and backlit keyboard complete the mobile workstation kit.

Questions about this item

How do I attach the Duex Max DS 14-inch FHD monitor to the laptop and which port should I use?

Connect the Duex Max DS monitor to either Thunderbolt 4 port using its USB-C cable; the laptop supplies video and power over the same connection.

What component will need replacement first and can I upgrade the memory later?

The 78 WHr battery is the only user-replaceable part; the 32GB LPDDR5X memory is soldered and cannot be upgraded.

What thermal limit appears first when the Ultra 9-288V runs at 5.1 GHz for extended periods?

The 65W power adapter caps sustained performance, so the CPU throttles before the cooling system reaches its maximum.
