I recently calibrated my U2412M Monitor and have since noticed I have soft blurry text that occurs down the page. The area of the soft text can occur down the left hand side, middle or right. I recall having this issue when i purchased it new, but can't recall how I solved it. Also when going into my Lightroom software, when on the import screen, I get flickering occurring. None of this used to happen before the calibration

Any help would be appreciated
