How bright should an outdoor display be?

Brightness is the first thing that separates a screen you can watch outside from one you can’t. It is measured in nits (candelas per square meter). Most indoor TVs are designed for living rooms, where a few hundred nits is plenty. Outdoors, the sun and every reflective surface around the screen compete with the picture.

A practical way to think about it

• Fully shaded, evenings only: a bright indoor-class screen can be watchable after dark, but it struggles in the afternoon.
• Covered patios and porches: daylight still reaches the screen from the open sides, so you want considerably more brightness than an indoor TV.
• Partial or direct sun, signage that must read all day: this is where high-brightness displays in the thousands of nits earn their place.

SSI HighBright displays run at 3,000 nits on every size, which keeps the picture readable in daylight.

Brightness alone isn’t the whole story

Glare washes out a picture as much as low brightness does. The HighBright glass is anti-glare and anti-reflective and is bonded across the full panel, which reduces internal reflections between glass and screen. Placement still matters: avoid aiming the screen straight at a pool, a white wall or a west-facing window.

Too bright at night is the other problem. A built-in light sensor turns the brightness down as daylight fades, so the same screen works at noon and at movie night.

Checklist

• Where is the sun at the hours you’ll use the screen?
• What reflective surfaces face the screen?
• Is the screen covered, partly covered or open?
• Will it show video, or text that must be read at a distance?

Next: choose a size or compare prices.
