Why each option

Screen flickering is caused by an incorrect or unsupported monitor refresh rate, which is adjusted under Display Settings via the Adapter properties.

ADisplay -> Settings -> Advanced -> General -> DPI

DPI (dots per inch) under the General tab controls text and element scaling, not the screen refresh cycle.

BDisplay -> Settings -> Resolution

The Resolution setting controls the pixel dimensions of the display, not how frequently the screen is redrawn.

CDisplay -> Settings -> Advanced -> Adapter -> RefreshCorrect

The refresh rate setting controls how many times per second the display image is redrawn; an incorrect rate causes visible flickering. In Windows Control Panel, this is found under Display - Settings - Advanced - Adapter - Refresh Rate (List All Modes), where a compatible rate can be selected for the monitor.

DDisplay -> Appearance -> Effects -> Transition

Appearance - Effects - Transition controls animated visual effects for menus and windows, unrelated to hardware flicker.
