TCL 55Q7D Pro vs Samsung QE55QN70H Comparison
The TCL 55Q7D Pro is the better choice for most buyers who want a faster and more gaming-focused 55-inch TV, thanks to its 144Hz refresh rate, VRR, HDMI 2.1 and AMD FreeSync Premium Pro support. The Samsung QE55QN70H counters with a strong Mini LED feature set, Samsung's NQ4 AI Processor, 7 years of OS upgrades, HDR10+ Adaptive and useful smart-home features. Both TVs offer 4K resolution and Quantum Dot technology, but their priorities are different. Choose the TCL 55Q7D Pro for high-refresh-rate gaming and Dolby Vision; choose the Samsung QE55QN70H for Samsung's software ecosystem, long-term OS support and AI picture features.
The TCL 55Q7D Pro has a major advantage for gaming with a 48–144Hz native refresh rate, VRR, ALLM, high-frame-rate support, two HDMI 2.1 ports and AMD FreeSync Premium Pro. The Samsung QE55QN70H is limited to a 60Hz native refresh rate in the listed specifications, although it includes ALLM, Game Bar, AI Auto Game Mode, Gaming Hub and HGiG.
Both TVs use Quantum Dot technology and 4K resolution, but their HDR approaches differ. TCL lists a 2000 cd/m² peak brightness and supports Dolby Vision, Dolby Vision IQ, HDR10+, HDR10+ Gaming and HLG, while Samsung adds HDR10+ Adaptive, HDR remastering and AI-based picture features through its NQ4 AI Processor.
The TCL 55Q7D Pro runs Google TV with Google Assistant, Google Cast and AirPlay, while the Samsung QE55QN70H uses One UI Tizen and adds 7 years of OS upgrades, Samsung TV Plus, Gaming Hub, Samsung Daily+, Samsung Health, Bixby and SmartThings support. Samsung is therefore more feature-rich for users invested in its wider ecosystem.
TCL offers four HDMI ports with two HDMI 2.1 inputs, one USB 3.0 port and a built-in 20W subwoofer alongside its 2 × 10W speakers. Samsung has three HDMI 2.0 ports and two USB 2.0 ports, but adds features such as Q-Symphony, Object Tracking Sound, Adaptive Sound and Bluetooth audio.
