When deploying digital signage networks, one of the most critical decisions is selecting the correct display panel brightness (measured in nits). Selecting too low of a brightness panel results in washed-out images under bright lighting, whereas selecting too high of a brightness panel inside offices leads to visual fatigue and excessive energy consumption.

Understanding Nits and Lux

A nit (candela per square meter) is the standard unit of measurement for screen brightness. The rule of thumb for B2B signage deployment is:

• Indoor Office / Meeting Rooms: 350 to 500 nits. This provides comfortable reading under standard ambient office lighting (around 500 lux).
• Window-Facing / Semi-Outdoor Displays: 1,500 to 2,000 nits. Required to overcome reflection from bright daylight.
• Outdoor / Direct Sunlight: 2,500+ nits. Must feature high-contrast filters to maintain readability during peak summer sunlight.
