Question How can I stop the backlight turning off when the display output to my LG monitor is black?

[BKsniperguy]

I have an LG 22MP55 and the backlight keeps turning off when the screen is mostly black. I HAVE "DISABLED" THE BUILT IN POWER SAVING FEATURE AND IT DISABLED THE AUTO DIMMING BUT IT KEEPS DOING THIS. At this point I don't even care if I have to break the thing open.

And your problem is that it doesn´t turn on anymore after this? Do you have to turn off and on to get a picture then?
