Expert LCD Brightness Max = Sounds Best?

[hardcore]

I always had auto dim active, but after removing the wifi cards the displays are switched on again. If you find a way how to avoid this would be greate...

I also have the Wi-Fi cards removed, and the auto dim is working for me on both units. I only have XLR and Optical 1 inputs enabled. When I set up auto-dim on either input, it works and turns off the display on both units.

Do you have Ethernet enabled? Do both displays switch on or only the master / companion?

In my configuration files, the relevant section looks like this. It is set per input, and set on both Master and Companion config files:

    "XLR":{
      "BACKLIGHT_MAX_LEVEL":100,
      "_auto_dim_timeout":3,
      "BACKLIGHT_TIMEOUT":3,

Here are some ideas to try:

In the web configurator: In the remote-control settings, disable "App Remote Control". In the Wifi settings, remove your wifi ssid and password configuration.

I also tried deleting these lines in the Master config file:

  "WIFI_CONFIG":{
    "DEVICE_NAME":"My Devialet",
    "SSID":"",
    "KEY":"",
    "DHCP":"ON",
    "IP_FIXED":"192.168.0.77",
    "ADHOC":"OFF",
    "IP_MASK":"255.255.255.0",
    "IP_GATEWAY":"192.168.0.1",
    "IP_DNS":"",
    "ADHOC_CHANNEL":6
  },
  "ETHERNET_CONFIG":{
    "DHCP":"ON",
    "IP_FIXED":"192.168.0.77",
    "IP_MASK":"255.255.255.0",
    "IP_GATEWAY":"192.168.0.1",
    "IP_DNS":""
  },

I also changed the USB_INIT to OFF on both Master and Companion and it works fine. Sounds more open too.

  "CONTROL_CONFIG":{
    "USB_INIT":"OFF",

If you want to manually edit the config files, you need to update the CRC checksum using the procedure described here:

manually manipulating dp_cfg.txt (devialetchat.com)
