After researching this problem further I found others complaining of the same issue, and the 'auto calibration' button fixed it. How to calibrate your screen, and looked for the 'auto calibration' button you describe in the article, but cannot find it on my monitor. This only seems to happen when the games change resolution to 1024x768 - however, in Windows 7, changing resolutions worked flawlessly. When this happens, my screen shifts to the left, leaving a black bar of about 4 centimeters on the right side. Since the upgrade, I have encountered problems with my screen shifting whenever I play some games. I just upgraded to Windows 10 and am using a monitor with 60hz and 1600x900 resolution.
