  1. Q2 202670/1005.0★5 レビュー

    Buyers praised the monitor's picture quality, color vibrancy, and smooth 300Hz performance. One report of a stuck pixel and no VESA mount noted.

    • Outstanding picture quality, vibrant colors, and deep blacks.
    • High refresh rate (300Hz) and smooth gameplay performance.
    • One unit had a stuck pixel near the middle of the screen.
    • No VESA mount; stand is nice but limits mounting options.
  2. Q1 202640/1003.8★15 レビュー

    Buyers praise the monitor's gaming performance, colors, and price, but many report poor build quality, confusing on-screen menus, and quality control issues like dead pixels.

    • Great gaming performance with high refresh rate, vibrant colors, and good value for the price.
    • Confusing on-screen menu system and poorly written manual make picture adjustments difficult.
    • Quality control problems include dead pixels, debris inside screen, and flimsy plastic stands.
    • Warranty support is lacking; claims for defects are ignored or passed to sub-contractors.
