Ok , here is a better pic. I think it may be the inverter. Anyone know? It's a shadow which moves from top to bottom continuously. The photo captures one moment as it vertically crosses the screen.
My monitor, the same model is doing the same. On the left side has black horizontal alternated lines and every second or so, there's a bright large bar going from top to bottom. All this fades to the right half of the screen, where it seems to be unnaffected.
