Samsung 55" 4K Smart TV | UA55DU7000UXTW
The Samsung 55" Crystal UHD DU7000 (UA55DU7000UXTW, 2024) is a 55-inch 4K LED smart TV with a 3840 x 2160 resolution, Samsung's Crystal Processor 4K and HDR10+ support. It runs Samsung's Tizen Smart TV platform, has 20W 2-channel sound with OTS Lite, and connects over Wi-Fi 5, Bluetooth 5.2, three HDMI ports and Ethernet.

Crystal Processor 4K and 4K upscaling: The processor drives the 4K picture and upscales lower-resolution content toward 4K, so regular TV channels and HD streams look sharper on the 55-inch panel. Mega Contrast, UHD Dimming and Motion Xcelerator are part of Samsung's picture processing on this model.
HDR10+: The TV plays HDR10+ content, which adjusts brightness and contrast scene by scene on supported streams and discs. Filmmaker Mode shows films closer to how the director intended.
Tizen Smart TV: Samsung's Tizen platform gives access to streaming apps, a web browser and the SmartThings hub for compatible smart home devices. Phones can share to the TV with Mobile to TV and Apple AirPlay, and Bixby voice control is ready.
Gaming features: Auto Game Mode (ALLM) switches to game settings when a console is detected, and the TV supports VRR and HGiG. The HDMI inputs accept 4K at 60 Hz.
Sound: 20W two-channel speakers with Object Tracking Sound Lite (OTS Lite) and Adaptive Sound. Q-Symphony lets the TV speakers play together with a compatible Samsung soundbar.
Good to know: The panel refresh rate is 50 Hz. The TV has a built-in tuner (DVB-T2/C/S2) with terrestrial, cable and satellite RF inputs, and it stands on two flat feet.
