Can a monitor arm cause screen flicker or display issues?

A monitor arm does not cause screen flicker or display signal issues — it is purely a mechanical device with no electronic components. Screen flicker is caused by: loose or faulty video cables (the arm's cable channel may create stress points if cables are routed too tightly — avoid sharp bends at pivot joints); a failing monitor power supply; incorrect refresh rate settings; or a failing video cable connector. If flicker appears after installing a monitor arm, check that cable routing through the arm does not create kinks or sharp bends, and that all connectors are fully seated.
