A friend gave me an MSI monitor while moving, but the original power adapter was lost. I tried finding a replacement through the manufacturer's site but wasn't sure which one to choose. The label appears to identify the monitor as a 3DA6 model. What voltage, amperage, connector type, and replacement adapter should I look for so I can use it safely?

If the model marking is 3DA6, look specifically for a replacement power supply listed for that monitor model. A compatible model-specific adapter is safer than choosing one based only on wattage, since the plug size and polarity also need to match.
You can search for “replacement power supply” together with the exact model number printed on the monitor label. Before connecting anything, compare the replacement’s output voltage, current rating, connector, and polarity with the specifications printed on the monitor.
The label appears to indicate a 20V, 3.25A power requirement, which works out to a 65W adapter. Search for an MSI 65W replacement adapter, but make sure the connector style and polarity match the monitor before buying. The photo isn’t clear enough to confirm whether it uses USB-C or a barrel connector.
