Overview
Not an LED set with a backlight to manage, this OLED lights its self-lit pixels directly and uses the screen itself as the speaker through Acoustic Surface Audio+. The XR Processor handles clarity and motion, and Google TV with Google Assistant runs the apps.
Pixel-level control and Dolby Vision support lead the list, with AirPlay and Chromecast casting built in. The bundle adds a long protection plan. Energy draw is high and the contents list is short.
Who it's for
A large media room where film contrast and a clean, speaker-free look matter. Buyers who need lower energy use or a smaller screen should look at other sizes.
Pros and cons
- Self-lit OLED pixels
- Dolby Vision and HLG support
- Screen doubles as the speaker
- Google TV and Google Assistant
- High listed power consumption
- Speaker power not listed
- Cables missing from box list
Performance notes
Self-lit pixels are controlled individually, so black areas switch off rather than glow, which sets the contrast. The processor adjusts clarity and the OLED motion handling tunes fast scenes. Audio comes from the screen surface, so there are no separate speaker grilles.
