What Customers Say

Owners of the 4‑Series 50‑inch model like the broad selection of streaming apps and the familiar Fire TV interface, noting that it is easy to set up and offers decent upscaling of low‑resolution content. They also appreciated that the screen handles reflections reasonably well and has low input lag for casual gaming. Nevertheless, several reviewers warn that the panel has narrow viewing angles and loses colour and contrast when you sit off‑centre, and the picture looks dim in bright rooms. Response times are slow, so fast motion appears blurry, and the TV lacks the brightness and colour punch needed for impactful HDR.
