77 inch BRAVIA 8 OLED TV

The Sony K77XR80B is a 77 inch BRAVIA 8 OLED 4K Google TV featuring over 8 million self-lit pixels for precise contrast and deep blacks.

Best for cinema-grade picture quality

This TV suits viewers who prioritise per-pixel lighting control, high luminance highlights and advanced processing for upscaling and motion clarity. Buyers needing a smaller screen size or a different operating system ecosystem should look at alternative models.

Sustained brightness and processing stability

The high luminance panel works with a temperature sensor and XR Contrast Booster to manage heat during extended viewing, maintaining consistent peak brightness and colour accuracy. XR OLED Motion and XR Clear Image handle fast action and noise reduction continuously without frame drops or processing lag.

Questions about this item

Do I need an HDMI 2.1 cable to use the 77 inch BRAVIA 8 OLED 4K Google TV with my PC?

The TV supports 4K resolution; use a certified HDMI cable rated for the bandwidth your source requires.

Will my older soundbar with only optical output work with this Sony TV?

Connect the soundbar to the TV's digital audio output; the TV passes stereo and encoded surround formats through that port.

How can I confirm the XR Processor is upscaling correctly after setup?

Play a 1080p source and open the picture menu — the information banner shows the detected input resolution and the active output resolution.
