Questions about this item
Will my older USB 2.0 peripherals still work with the two USB 3.2 Gen 1 ports and single USB 2.0 port?
Yes, the USB 3.2 Gen 1 ports are backward compatible with USB 2.0 devices, and the dedicated USB 2.0 port provides a native connection for legacy peripherals.
How can I verify the 120Hz panel is actually running at 120Hz after setting up Windows 11?
Open Settings, choose System, then Display, and confirm the refresh-rate dropdown shows 120Hz for the built-in 15.6-inch FHD screen.
Does the box include an HDMI cable for the HDMI 1.4 port, or do I need to buy one separately?
The laptop ships with the power adapter only; an HDMI cable for the HDMI 1.4 port must be purchased separately.
