David Grayscale control: Determines the depth of the image. A high grayscale screen preserves detail in dark areas and avoids overexposing bright areas. When watching movies or sports, the starry sky and highlights on the field are accurately rendered.
Refresh rate: Affects image smoothness. A screen with a low refresh rate can cause artifacts in fast-moving images. For live sports broadcasts, a refresh rate of at least 3840Hz is required to ensure smooth, seamless playback of players and balls.
Intelligent temperature control: Large screens consume high power and generate significant heat. A good display features built-in intelligent temperature control. If the temperature rises too high, it automatically adjusts the fan and even uses water circulation to maintain the lifespan of the LEDs and maintain image stability. Imagine a large outdoor screen blacked out in the summer due to heatstroke. The impact on viewing quality is immense!
