SUMMARY After I change the screen resolution from 1280x720 to 1920x1080 (or vice versa), the visible output size is not changed accordingly. STEPS TO REPRODUCE 1. Change the screen resolution from 1920x1080 to 1280x720 OBSERVED RESULT The visible output size is old, and the whole screen is blurry. For example, the size of the visible area is still 1280x720 but scaled to 1920x1080, and the remaining area is outside of the screen.
