it is in a cocktail cabinet , to the left of the monitor is a fan, as in most cocktail cabinets,
also it was recently transported to my house and it was ok before the journey,
i live in uk, sheffield and there are road humps all over the place, so maybe this hasnt helped ,
the guy who i bought it off said it was fine before transporting it to me( but maybe didnt notice!)
The cabinet is moon cresta, i was thinking of replacing the monitor anyway but the colours look really nice on this monitor, so if i can fix the picture ,i'll keep it
