Picture & Audio Quality
Refresh Rate
How many times per second a display updates its image, measured in Hertz (Hz) — commonly 60Hz, with 120Hz on newer gaming-focused hardware.
For standard IPTV streaming, content delivered at 24, 30, or 60 frames per second doesn't require the higher 120Hz refresh rates that features like HDMI 2.1's VRR specifically target — those matter much more for gaming than for typical live channel or on-demand viewing.
