Sorry to answer this late, but since no one was alking by here... I have searched more in a couple of Facebook groups I am in and 3 out of 5 people I reached about this Samsung model had either way an issue like mine or some other thing with bleeding, even worse. One of the guys got 2 monitors and he says both are fine, luky guy. Another never answered. So I guess, in my case, the QA people on the Samsung factory where I bought it is not really thorough on the process.
