What Customers Say

owners praised this 77-inch model for its perfect blacks without blooming, broad viewing angles and excellent reflection handling, vivid colours and high HDR brightness with low input lag; but people mentioned its black levels rise under ambient light and no Dolby Vision, slight stutter due to fast response times, out‑of‑box colour may need tweaking for accuracy. In summary, the feedback suggests a television that excels in certain areas yet leaves some room for improvement.
