Question about LG 55UP77009LB
Despite correct default settings, the monitor always switches off after four hours (switch-off function OFF, economy mode OFF, timer settings according to opening hours). The TV is in a showroom and should run for at least 10 hours without interruption. A Rasperry Pi is connected via HDMI. Can this problem be solved by a software update? Any other suggestions for a solution?
The TV has an eco-mode, you should also switch this off, then the TV will not switch itself off after a certain time.
