Questions about this item

How do I confirm the 240 Hz panel is running at full refresh after Windows 11 Pro setup?

Open Settings > System > Display > Advanced display and verify the refresh rate dropdown shows 240 Hz for the 18 inch 2560 x 1600 panel.

What ships in the box and what must I source separately for the G815LW-G18.U95080?

The laptop, power adapter and documentation are included; no additional RAM, storage or OS licence is required because 32 GB DDR5, 2 TB NVMe SSD and Windows 11 Pro are pre-installed.

Which configuration should I choose between the listed Ultra 9-275HX and RTX 5080 versions?

Only one SKU is listed — Ultra 9-275HX with 24 cores, RTX 5080 16 GB GDDR7, 32 GB DDR5 5600 MHz and 2 TB PCIe 4.0 x4 NVMe — so no alternate version exists to select.
