My ASUS LCD monitor will sometimes black out with indicator led ON and won't return to normal unless i turn off and on again (monitor is still detected as ON by computer). This has been happening for long enough (5 yrs) and isn't frequent (usually happens once a month/two months)
-I've changed hdmi cables, monitor power cords, power outlets, i even change from computer to a totally different one.
-I'm not sure if monitor is broken since works fine most of times and this is not that frequent. I do a heavy usage of him.
-I suspect something related to home wiring interference or a power sag but I'm not sure if it's possible since this is the only device i notice some malfunction.
This is bugging me and i have no clue.
