Has anyone else had issues with the LAN port on Samsung QM displays going to sleep?? I have two QM75R displays controlled over LAN as Crestron Connected Devices.? I had no trouble controlling them initially, but two days later I found them not responding and not connected in the IP table.? After I manually turned display power on they showed as connected again, and showed as connected the rest of the day, even when power was off.? A few days later I found the same situation.? I have disabled every energy saving function I can find in the menu.?
