18-inch Mini LED 240 Hz display

The 18 inch panel uses Mini LED backlighting at 2560 by 1600 resolution with a 240 Hz refresh rate and 3 ms response. Anti-glare coating keeps reflections low in bright rooms. The 2.5K pixel density makes text sharp and game detail clear.

24-core Ultra 9 plus RTX 5080 for heavy workloads

The Intel Core Ultra 9 275HX runs 24 cores at up to 5.4 GHz with 36 MB cache. The GeForce RTX 5080 adds 16 GB GDDR7 memory. This combination suits 4K content creation, high-refresh competitive play and local AI inference. Buyers who only browse the web or edit documents will not use this headroom.

16 GB DDR5 and 1 TB PCIe SSD baseline

The system ships with 16 GB of DDR5 memory and a 1 TB PCIe solid-state drive. That capacity handles current AAA titles and moderate creative projects without swapping. Large texture packs, virtual machines or multi-project timelines will fill the drive and memory quickly.

Questions about this item

What external display cable do I need to use the 2.5K 240Hz panel over Thunderbolt 5?

Use a Thunderbolt 5 cable that carries DisplayPort; the laptop has two Thunderbolt 5 ports supporting DisplayPort and power delivery for the 2560 x 1600 240Hz signal.

Will my USB 3.2 Gen 2 Type-A peripherals work at full speed on the three Type-A ports?

Yes, the three USB 3.2 Gen 2 Type-A ports run at 10 Gbps, so existing Gen 2 devices operate at their rated throughput.

How can I confirm the Mini LED panel is running at 240 Hz after driver installation?

Open Windows display settings or the NVIDIA control panel and verify the refresh rate shows 240 Hz for the 2560 x 1600 resolution.
