ASUS has published a price list for the ROG Zephyrus G14 and G16 series laptops unveiled at CES 2026. The devices are far from budget-friendly: for the price of some models, you could buy a top-of-the-line gaming desktop.
MSI has begun sales of the Titan 18 Ultra (2026) gaming laptop. The new model stands out even in the flagship segment, both for its hardware configuration and its impressive retail price.
LG has announced the launch of production of an LCD display for laptops, whose main feature is support for a refresh rate starting at 1 Hz. The new product is positioned as an alternative to LTPO smartphone panels, which will improve the battery life of portable PCs without compromising image quality.
