18-inch Mini LED 4K 120Hz display

The 18-inch Mini LED panel shows 3840 by 2400 pixels at 120 Hz. That resolution and refresh rate suit competitive gaming and colour-critical content work. The 16:10 aspect gives extra vertical space for timelines or code. Bright highlights and deep blacks come from the Mini LED backlight.

Mobile workstation buyers and high-refresh gamers

Creators who need 128GB DDR5 SO-DIMM and an RTX 5090 with 24GB GDDR7 will use the headroom for 3D rendering or large dataset training. Gamers chasing 4K 120 Hz frame rates on the internal screen also fit. Ultra-portable seekers or buyers on a strict budget should look elsewhere.

RTX 5090 24GB GDDR7 graphics

The dedicated GeForce RTX 5090 with 24GB GDDR7 is the single spec that decides fit. It drives the internal 4K 120 Hz panel and external displays over HDMI or Thunderbolt 4. If your workload does not need that GPU tier, a lower configuration will cost less.
