The Samsung QE77S99HXUXUA is a 77-inch 4K UHD television that utilizes QD-OLED technology to deliver deep blacks and vibrant colors. At its core, the NQ4 AI Gen3 processor optimizes the image quality, while a 165 Hz refresh rate and Motion Xcelerator ensure that fast-moving scenes remain smooth. Support for HDR10+ allows for a wider range of contrast and detail in both bright and dark areas of the screen. Designed with a sleek black finish, the display is remarkably thin at 26.6 mm without its stand, making it a discreet addition to your living space. For those who enjoy gaming, the inclusion of AMD FreeSync Premium Pro prevents screen tearing, providing a more fluid experience. The Tizen operating system manages the smart features, which are supported by Wi-Fi 802.11 ax and Bluetooth 5.3 for stable wireless connectivity. Audio is handled by a 4.2.2 channel system with 70W built-in speakers and Dolby Atmos, creating an immersive soundscape that complements the large screen. You can connect your devices via four HDMI ports, including one with ARC, or use the two USB Type-A ports for external media. With a weight of 32.2 kg including the stand, it can be placed on a sturdy surface or mounted to a wall using a 400x400 VESA bracket.
