There are physical limits to the size, mainly determined by the size of the filter capacitors in the front-end power supply. The capacitors have to have enough microfarads to supply current between AC cycles. There also has to be a transformer and those can be made smaller, to a point, but there are limits there too. Therefore, you need to ensure that the charger you get is 19.5V. The issue then is, does your specific laptop use the 3.34amps or the 4.62? If you aren’t sure and cost is the same, just go for the higher amperage (therefore wattage) one. As long as the volts are correct, you wont damage the device. How do AC adapters work, and why are they so large? The adapter output voltage needs to closely match the monitor requirement. (V-monitor -1v)

The reason I say reasonably sure without damaging the monitor is that the internal regulators that operate off the 12vdc, normally will now get hotter because of the higher input voltage. This could eventually cause a failure of the internal regulator if it gets much hotter than the design can handle. But this should be OK if the monitor is not used in a room that is excessively hot like 40–60°C. My laptop is rated "19.5V - 3.34A / 4.62A", should I buy a 65W or a 90W AC adapter?VGP-AC19V76 VGP-AC19V28 VGP-AC19V42 VGP-AC19V59 VGP-AC19V60 VGP-AC19V34 VGP-AC19V38 VGP-AC19V44 VGP-AC19V47 VGP-AC19V49 First the power requirement of the monitor must be known. This information is on the product safety label usually on the rear of the device. What is needed is the voltage and current or voltage and power requirement.

Adapter has 13.5vdc output. Monitor requires 12vdc. 13.5vdc > 12vdc OK. 13.5vdc < 12vdc + 2vdc = 14vdc OK.
