I have an LG display with this anti-feature built in as well. An amusing anecdote about that: The OSD is not documented very well. There's a feature named “SUPER ENERGY SAVING” and a feature simply named “DFC”. As I learned via google, “DFC” is supposed to mean “Digital Fine Contrast”.
Now, about these two features: One of them turns off the backlight when I lock my screen, the other adjusts the backlight intensity automatically based on the display contents.
Did you think “SUPER ENERGY SAVING” was the first and “DFC” was the second? Nope, of course not - it was the other way around. “SUPER ENERGY SAVING” advertises itself as “saving energy” by reducing the backlight intensity when it's “not needed as much”, and “DFC” advertises itself as increasing the “dynamic” contrast (by basically turning off the backlight during the black frame test pattern).
Good job LG. This is actually one of the least sad bits about the OSD's horrible design and implementation.
