Choosing a flat-screen TV involves selecting display technology, with OLED offering superior contrast for dark rooms, while QLED and Mini-LED provide high brightness suitable for well-lit environments. For optimal performance, particularly for gaming, consumers should prioritize native 120Hz refresh rates and HDMI 2.1 support over 8K resolution, which currently lacks content.
