Display14-inch OLED; 2880 × 1800 (3K); 16:10; 120 Hz; Pantone Validated ASUS16-inch WQXGA (2560 × 1600) IPS, non-touch, 500 nits, anti-glare, 16:10, 1200:1, 100% DCI-P3, 240 Hz; DisplayHDR 400, Dolby Vision, G-SYNC, X-Rite factory calibration

DisplayHDR 400 is VESA’s entry-level HDR tier; it does not require local dimming, so HDR looks less striking than on OLED or Mini LED. 240 Hz and G-SYNC give smooth, tear-free motion in fast games. Lenovo notes that “IPS” may also cover similar panel types such as PLS, ADS and AHVA.

Lenovo
Display featuresROG Nebula HDR; 1100 nits peak brightness; VESA DisplayHDR True Black 1000; 100% DCI-P3; 0.2 ms; G-SYNC; ambient light sensor

HDR peak brightness is not a sustained full-screen figure. ASUS’s January 2026 introduction gives 1000 nits peak; the 1100 nits from the sales announcement is used.

Memory16 GB LPDDR5X-8533, onboard; no slot, not upgradeable

ASUS lists this model code in both 16 GB and 32 GB columns; this entry is the 16 GB column. Actual memory speed may vary by processor configuration.

ASUS		1 × 16 GB DDR5-5600 SO-DIMM; two slots, dual-channel capable; up to 32 GB in Lenovo’s offering

This configuration ships with a single module, so memory runs single-channel until a matching module is added to the second slot. Lenovo’s 32 GB limit is based on the modules it has tested.

PCIe 4.0 x4 allows up to 8 GB/s in theory; real speed depends on the SSD. There is no card reader.

Graphics—NVIDIA GeForce RTX 4080 Laptop GPU, 12 GB GDDR6; 2280 MHz boost clock, 175 W TGP, 542 AI TOPS

175 W is the highest total graphics power Lenovo allows in this model; going above NVIDIA’s 60–150 W base range for the RTX 4080 Laptop GPU relies on Dynamic Boost 2.0. The desktop RTX 4080 is a different product.

Lenovo
Ports—1 × Thunderbolt 4 / USB4 40 Gbit/s (DisplayPort 1.4), 1 × USB-C 10 Gbit/s (Lenovo PD 140 W, DisplayPort 1.4), 4 × USB-A 5 Gbit/s (one Always On), 1 × HDMI 2.1 (up to 8K/60 Hz), 1 × RJ45 Gigabit Ethernet, 3.5 mm audio

140 W charging over USB-C needs Lenovo’s own adapter; other adapters may deliver less. Up to four independent displays including the internal one are supported; Lenovo lists up to 4K/60 Hz for external outputs. Ethernet is 1 Gbit/s, not 2.5G, and supports Wake-on-LAN.

Battery and power—99.9 Wh lithium-ion, Super Rapid Charge; 330 W slim-tip GaN adapter

Lenovo says Super Rapid Charge reaches 30% in 10 minutes, 70% in 30 minutes and 100% in 80 minutes. 99.9 Wh sits just under the usual airline battery limit. Lenovo quotes 10.4 hours of 1080p video playback at 150 nits.
