Product Info

Its street price of around ¥44,980 offers competitive value for a QHD 180Hz curved VA panel with wide color gamut and HDR support.

Best Use Cases

Competitive and immersive gamers: The 180Hz refresh rate and 1ms response time give a clear edge in fast-paced titles, while the 1500R curve enhances immersion in open-world and simulation games. Users who value deep blacks and contrast: VA panel technology delivers a 3000:1 contrast ratio, making dark scenes in horror games or movies look more realistic. * Content creators needing accurate colors: DCI-P3 95% coverage is sufficient for photo editing and video color grading, though professionals may still prefer an IPS panel for wider viewing angles. If you require 240Hz or higher for competitive esports, or need the widest possible viewing angles for multi-monitor setups, an IPS-based alternative might be a better fit.

Things to Consider

VA panel viewing angles are narrower than IPS; color and contrast shift when viewed from the side. Position the monitor directly in front of your seating area. HDMI input is limited to 144Hz. To achieve the full 180Hz, use the DisplayPort connection. The monitor weighs approximately 9.6kg with the stand. If using a VESA mount, verify it can support this weight. The zero-bright-dot warranty is exclusive to the model. Check warranty terms before purchase if buying from other channels. ## FAQ
