Important Buying and Safety Advice

• Check the Voltage: When replacing your LG monitor charger, always confirm that the output voltage is exactly 19V.
• Understand Amperage: It is completely safe to use a higher current adapter (for example, using a 1.7A charger on a 1.3A monitor) because the monitor will only draw the power it needs. However, you must never use an adapter with a lower current rating than your monitor requires.

Additionally, always double-check the physical connector tip to ensure it contains the necessary center pin, which is essential for stable power delivery and a secure connection.
