When in epics7 a channel or pv is monitored with a deadband (perhaps also in 3.15), then a value
will only be given when the value exceeds the deadband. This is the expected behaviour. However in case of a display manager, no value will be displayed when monitoring values until the deadband is exceeded. This seems to me a rather special behaviour for
existing display managers that rely on monitoring the values.
Perhaps I am wrong, but perhaps a first value should be send?
