78W 19V AC adapter for Samsung monitors
This 78 watt AC adapter supplies 19 volts at 4.19 amps through a 6.5 by 4.4 millimetre barrel plug with a centre pin. It is built as a direct replacement power supply for the listed Samsung LCD monitors. The unit carries CE certification.
Fits LC27FG70F, LC27FG73FQ and CF791 series
The adapter accepts 100 to 240 volt input at 50 to 60 hertz, so it works with mains supplies worldwide when paired with the appropriate EU, US, UK or AU power cord included in the package. A single cable connects the brick to the monitor, freeing the display from a bulky internal power board.
Replaces lost or faulty BN4400888A units
If the original charger is missing, damaged or no longer holds voltage, this model restores full operation without modification. The jump is worth it when the monitor shows no power LED, intermittent shutdowns or a blinking screen caused by an unstable supply.
