18″ UHD+ Mini LED display

The 18-inch panel delivers a 3840 x 2400 UHD+ resolution at a 120 Hz refresh rate using Mini LED backlighting. That pixel density and brightness level suit colour-critical creative work and high-detail gaming on a single screen.

Best for stationary power users

This configuration targets creators and engineers who need 96 GB of DDR5 memory, 16 TB of PCIe 4.0 NVMe storage and an RTX 5080 GPU in one chassis. Mobile professionals who prioritise battery life or a lighter 7.94 lb form factor should evaluate thinner alternatives.

16-core Ryzen 9 9955HX3D with 128 MB cache

The processor combines eight performance and eight efficient cores, reaching a 5.4 GHz maximum turbo frequency. Its large L3 cache and 16 GDDR7 video memory on the RTX 5080 decide whether the system meets your compute and graphics workload.

Questions about this item

What power adapter does the 16-core Ryzen 9 9955HX3D and RTX 5080 with 16 GB GDDR7 require?

The laptop ships with the MSI power adapter specified for this 18-inch configuration.

Will my existing DDR5 5600 MHz SO-DIMMs work alongside the installed 96 GB of memory?

The two 48 GB modules fill both SO-DIMM slots, so there is no free slot for additional memory.

How can I confirm the 18-inch UHD+ Mini LED panel is running at 120 Hz and 3840 x 2400 after setup?

Open Windows Display Settings and verify the resolution shows 3840 x 2400 with a 120 Hz refresh rate selected.
