The 14 inch 3K OLED panel uses a 16:10 aspect ratio with an anti-reflection coating, 100 percent DCI-P3 coverage, Delta E under 1 color accuracy, and a 120Hz refresh rate. It reaches 1100 nits of brightness, supports G-Sync and Adaptive-Sync, and includes Dolby Vision HDR and Pantone validation, delivering both sharp motion and genuinely accurate color.

At the core is the Intel Core Ultra 9 386H processor, running at 2.1GHz base and boosting up to 4.9GHz across 16 cores and 16 threads, with an NPU rated up to 50 TOPS. Paired with the NVIDIA GeForce RTX 5070 Ti 12GB GDDR7 GPU, this combination comfortably handles current AAA titles at high settings and native 3K resolution, while also serving demanding creative workloads like video editing and 3D rendering. 32GB of LPDDR5X 8533 RAM and a 1TB PCIe Gen4 NVMe SSD round out a well-balanced, high-performance configuration.
