How to Choose
When selecting a 70‑inch smart TV, start with the panel technology that matches your viewing environment. Mini‑LED and QLED excel in bright rooms thanks to high peak brightness, while OLED delivers perfect blacks for dark‑room cinema. HDR support is another key factor; look for models that handle both HDR10+ and Dolby Vision to future‑proof your purchase.
Next, consider connectivity. HDMI 2.1 is essential for 4K gaming at 120 Hz, and having at least two such ports gives flexibility for consoles and a potential PC hookup. Finally, evaluate the smart platform - Tizen, webOS, Google TV and Roku each have unique strengths. Choose the interface that feels most intuitive and supports the streaming services you use most often.
