I just recently noticed, when playing a video game, that during white letters display or small white objects on the screen there is a green-blue tint about half centimeter to the left.

It is the same as the what should appear but it is off center.

How can I fix that? How do I get into the calibration menu for this TV and what settings should I adjust?

It is already too late to return so I will have to try to fix it myself
