Marvel at the beautifully rich picture and sensational colours of Philips' POS901. 4K UHD resolution and OLED screen technology deliver an incredibly lifelike image with a stunning array of vibrancy and contrast. The brand's Perfect Pixel Ultra HD engine combines with HDR capability for the deepest blacks, brightest whites and an astonishing level of detail. The super-smart Android platform opens up a wealth of additional online features, while Visible Sound Articulation adds amazing depth and clarity to the set's audio. Uniquely, its Ambilight 3 Sided system extends the colour out into your living room by emitting a warm, vivid and changing glow onto the surroundings. Completed with razor-slim design, this is a super-sleek television with a breathtaking picture, and a sensational colour experience. OLED Screen At the forefront of modern audio-visual technology, the Organic LED display has broken new ground in picture detail. Unlike regular LED screens, this doesn't have a backlight, meaning that each pixel is self-illuminating. This allows every speck of light to control its own luminescence for true depth and colour gradation. So, you'll experience blacker blacks, whiter whites, and a more lustrous display. 4K UHD Picture To respond to screens getting bigger, brands have packed their screens with more pixels. This 55 inch screen has four times the number of pixels than 1080p HD TVs, delivering stunning realism, natural motion and incredible detail. Experience this high-spec picture across a range of broadcasts, movies, sports and more thanks to 4K upscaling. Driven by Philips' Perfect Pixel Ultra HD engine, as it converts lower resolution content to near-4K quality, anything you watch on the big screen will be truly extraordinary. Glorious HDR Armed with High Dynamic Range Perfect, the POS901 brings a new level of HDR contrast and colour to everything you watch. Deepening your view and showing shades you've never seen in home entertainment before, it reaches previously uncharted levels of vividness for a stunningly realistic picture. Usually, studios are forced to dilute the colour of their shows and films to fit on our TVs. Now, HDR screens like the POS901 can channel content from studio-to-living room with the same precision and utterly otherworldly hues.
