Important Compatibility Tip
Check Your Connector Size: Most monitor power ports use this 5.5mm x 2.5mm size. However, some smaller monitors may use a 5.5mm x 1.7mm (smaller inner hole) tip. If your current plug has a 2.5mm inner diameter (standard desktop power size), this adapter is the perfect fit.
