Smart Features

This TV’s Wi-Fi connectivity lets you access apps and online services including Netflix, YouTube and Amazon Prime. Enjoy the latest shows, films and video content at the touch of a button.

YouView and Freeview HD are also included, adding over 70 TV channels and a range of on-demand services. Watch your favourite shows live, or catch up on any you’ve missed.

Plus, Android’s Marshmallow 6.0 features on the KD55XE8577SU, giving the screen a clean and clear layout for finding content.

4K HDR Processor X1

Bringing together three of Sony’s picture-boosting technologies, the 4K HDR Processor X1 improves colour, clarity and contrast. These features include:

  • X-tended Dynamic Range Pro – by boosting the range of light and dark shades, this feature improves contrast. The screen’s unique backlighting system offers over three times the brightness range of other LCD TVs.
  • 4K X-Reality PRO – this feature improves image clarity, comparing each pixel onscreen to the TV’s picture database. Using this smart technology, details are restored that would otherwise be lost in transmission.
  • Triluminos display – By using a wider colour spectrum than other LCD TVs, this Sony feature prevents colour fade and gives more natural skin tones. Colours appear deeper and more vibrant.

The Sony KD55XE8577SU also uses Motionflow XR1000. When watching content, movements between frames can cause a ‘judder’ to the eye. This function inserts additional frames, ‘smoothing out’ footage. It also uses the panel’s LED backlight and blur reduction to make images appear sharper.

Additional Features

Connect a range of devices to the four HDMI ports at the TV’s rear, including games consoles and Blu-Ray players. You won’t need to keep switching between devices – just have everything plugged in and ready for when you need it.

You can even use voice control with the KD55XE8577SU. Simply press the remote’s microphone button and talk to your TV. No lengthy installations or set-ups are required – just pick it up and press to use.

This Sony TV also comes with a 2 x 10 W sound output, and offers full support for Dolby Digital, Dolby Digital+ and Dolby Pulse. Enjoy your content with a range of high-quality sound formats.

Offering a huge choice of shows, the Sony KD55XE8577SU also has image-boosting features so you can view them at their best. Order now.
