WCH Touch Driver 1.4.1

DisplayLink monitors now restore their saved WCH brightness after reconnecting, waking, or starting the driver. Restoration waits for the connection to settle and retries up to four times if DisplayLink does not acknowledge the setting.

Brightness status clears acknowledgements from earlier connections and reports restoration failures without discarding the saved level. Native brightness restoration is unchanged.

DisplayLink cannot read brightness changes made with a monitor’s physical buttons. Those adjustments work while connected; the next reconnect restores the level last saved by WCH.
