For a 500-square-meter conference room or lecture hall, P3 or P4 LED displays are typically chosen. These models offer suitable pixel density for viewing distances while ensuring image clarity and a good viewing experience.
The specific model chosen depends on factors such as the audience's maximum viewing distance and budget. If the audience seating is far from the stage, P3 might be a better choice due to its higher resolution.
If the budget is limited, P4 is also a cost-effective option. It is recommended to consult a professional LED display supplier for more detailed advice and customized solutions.
