- Q1 202688/100
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.

- 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.
