When sourcing LED screens, you must prioritize Pixel Pitch (P), which determines the minimum viewing distance; for indoor use, P1.2 to P2.5 is standard, while outdoor displays typically require P4 to P10. Additionally, evaluate Brightness levels, measured in nits—indoor screens should offer 800-1,200 nits, whereas outdoor screens must exceed 5,000 nits to remain visible under direct sunlight. Ensure the Refresh Rate is at least 3,840Hz to prevent flickering on camera, and verify the use of High-Quality LED Lamps (e.g., Nationstar) for color consistency and longevity.
