  1. Q1 202688/1004.8★4 reviews

    Buyers praised the monitor's picture quality, smoothness, and value, especially during sales. Some noted the side-mounted controller and lack of speakers as drawbacks.

    • Excellent colors, brightness, and picture quality; a major upgrade from older monitors.
    • High refresh rate and smooth performance, ideal for competitive gaming.
    • Side-mounted controller is awkward, especially in dual-monitor setups; software partially mitigates.
    • No built-in speakers, which was a disappointment for one buyer.
  2. Q4 202595/1005.0★3 reviews

    Buyers in Q4 2025 praised this 1440p 300Hz monitor for gaming, image clarity, and value. Setup was easy, and Amazon's secure packaging was noted. One mentioned color calibration needed out of the box.

    • Excellent 1440p gaming performance with 300Hz refresh, minimal ghosting, and sharp, bright visuals.
    • Great value for the price, especially as a primary or secondary monitor upgrade from 1080p.
    • Secure Amazon packaging with styrofoam and plastic bags ensured safe delivery.
    • Color accuracy off out of the box, but easily fixed with tweaking; not a dealbreaker.
