In real AV installs, it mainly depends on site access, not display type.

  • Front-service: Used when there’s no rear space (walls, façades, recessed installs).

  • Rear-service: Used for billboards, rooftops, or structures with rear maintenance access.

In r/CommercialAV discussions, the rule is simple: if rear access can’t be guaranteed long-term, front-service is the safer choice.

In practice, it’s a building constraint decision, not a screen feature.
