In general, the problem is ... I don’t know how, but the settings went wrong, I don’t even know what .. the red color began to prevail, there was almost no black.
monitor ACER AL1751 ... I press the AUTO button on it and it restores the colors for a couple of seconds as it was before, and then resets them or something .. I already climbed into the menu manually, into the screen setting too. I don’t know what to do
