The Samsung CU7000D is a 55-inch Class 4K UHD LED LCD television (model UN55CU7000DXZA) featuring a Crystal Display panel with a native 3840x2160 resolution and a sleek Titan Gray slim-look design. Powered by Samsung's Crystal Processor 4K, the TV upscales lower-resolution content to near-4K quality while PurColor technology expands the color palette for more vivid, lifelike imagery. HDR and HLG (Hybrid Log Gamma) support further enhances contrast and brightness for compatible content, and Filmmaker Mode preserves the original creative intent of films.

Motion Xcelerator at a 60Hz native refresh rate delivers smooth motion handling for everyday viewing and gaming. The set includes three HDMI 2.1 ports — one with eARC for audio return to a compatible soundbar and two with ALLM (Auto Low Latency Mode) that automatically switches to game mode when a console is detected. A digital optical audio output, built-in Wi-Fi, and Bluetooth round out the connectivity options. The 20-watt speaker system supports Object Tracking Sound Lite and is Q-Symphony compatible, allowing it to work in tandem with a Samsung soundbar for an expanded soundstage and Adaptive Sound for scene-by-scene audio tuning.

Running on Samsung's Tizen smart platform, the TV offers voice control through Amazon Alexa, Google Assistant, and Samsung's own Bixby, plus seamless SmartThings integration for smart-home control. Multi Device Experience features include mobile-to-TV screen sharing, Sound Mirroring, and Wireless DeX. Microsoft 365 is available directly on the TV for productivity. An Eco Sensor adjusts screen brightness based on ambient room light, and Auto Power Off conserves energy when no signal is detected. V-Chip parental controls, an Electronic Program Guide, and ATSC/ClearQAM digital tuner are also included. The set is VESA 200x200 wall-mount compatible, weighs 30.6 lb without the stand, and measures 48.4 inches wide by 2.4 inches deep by 27.8 inches tall without the stand. Costco includes free shipping, free technical support, and a 3-year manufacturer's warranty.
