    brilliant. Incredible picture and sound

    Except for the Remote Control, the whole process has been seamless and hassle free. The remote control is very sensitive particularly the sound button which makes it hard to operate.

    Samsung S90F O LED Is An Excellent TV.. Picture quality second to None, Whites Are White, Blacks Are Black, Colour renditions deep and rich.Sound very Simple to set up . Already recommended to family members as their Next TV.

    77" OLED TV picture is superb, 4K Ultra HD resolution Second to None, vibrant colours exceptional picture quality, and the fast refresh rate give smooth action when watching the footy, and very good upscaling watching non 4K video. Sound quality is greatly improved and have switched soundbar to an older tv. Plenty of Smarts packed into the remote / interface package with voice control, Wi-Fi 5 and Bluetooth 5.3 compatibility, multiple HDMI and USB ports. Best TV we have owned to date.
