  1. In the case of digital signage I suggest considering “a display” as a single very large display like a LED video wall or a display network, ie using multiple LCD displays. There are various reasons for considering or planning replacement:
    – Brightness, displays are about to fall below acceptable brightness levels;
    – Reliability, displays are approaching the end of expected operating life (presumably outages are unacceptable), the backlight and power supplies are likely to be the main lifetime constraints for a display and any mechanical parts like fans and hard-disks may have shorter life expectancy;
    – Operating cost savings from a new network justify the replacement.

    Another factor is display network expansion. It may make sense to replace the original installation if a network expansion will use different new displays with more advanced capabilities, with old displays it may results in working to the lowest common denominator in a display network.

    One of the challenges is the lead time for replacement, so letting things fail is very unlikely to be the best approach for deciding when to replace a display in a digital signage installation.
