What reviewers say
Reviewers agree it is an immersive, fast ultrawide OLED with a vivid, accurate picture and perfect blacks. They differ on HDR, which PC Gamer found superb and Tom's Guide dim; Tom's Hardware noted there are no speakers or headphone jack, and PC Gamer thought the older panel and modest pixel density a harder sell against 4K OLEDs at similar prices.
