I have an LG 55" client monitor and since a firmware upgrade a few months back now auto dims if the image on screen doesnt change after 2 mins. This is very annoying when you are sitting on a shot and the client says "why has the image gon dark?
There maybe a setting to turn this off in the settings (engineering) menu only accessible through a key combination but for the life of me I cannot get to it.
you have to get another remote then you can switch that setting off its a service remote, then type in the LG code which will unlock other settings, the code I can’t recall but I can find it if your unable too.
