Samsung QN90D 65" vs TCL QM8 65"
Both 65-inch Mini-LED TVs deliver impressive 4K performance, but serve different priorities. Samsung's QN90D ($1799) excels with superior brightness (4000 nits), advanced Neural Quantum Processor 4K upscaling, and premium 4.2.2ch object tracking sound—ideal for bright rooms and cinematic audio. TCL's QM8 ($999) counters with brighter peak brightness (5000 nits), Dolby Vision IQ support, Wi-Fi 6 connectivity, and matching gaming specs (5ms vs 6ms input lag, both 4K@120Hz). Picture quality edges toward Samsung's refined processing, though TCL's extra brightness handles glare better. Gaming performance proves nearly identical with both offering HDMI 2.1 support and low input lag. For value-conscious buyers prioritizing brightness and smart features, TCL represents exceptional savings without meaningful performance compromise. Samsung justifies premium pricing through processing excellence and audio sophistication. Recommend TCL QM8 for budget-conscious performance; Samsung QN90D for those valuing processing prowess and audio quality.
