Question about Mag Innovision LT576s 15" Flat Panel LCD Monitor
It is a good solution, but only use the Analog Volt Meter or multimeter (just $8 dlls in a electronic store) and make the first steps that guest wrote:
"Plug the red lead into the center post of the adapter and touch the black lead to the outside ring. With a DMV it should show a positive voltage if the center post is Positive or negative voltage if the center is Negative. With an analog meter (red - center) positive voltage, (black - center) the needle tries to swing to the left of 0 volts" it is enough.

Use a DMV (AKA Digital Volt Meter) or an Analog Volt Meter) to check the polarity of the plug. Not sure how to use a meter? Plug the red lead into the center post of the adapter and touch the black lead to the outside ring. With a DMV it should show a positive voltage if the center post is Positive or negative voltage if the center is Negative. With an analog meter (red - center) positive voltage, (black - center) the needle tries to swing to the left of 0 volts. Being 12VDC don't worry about being shocked the voltage and current is low enough that if you were to get shocked it feels like a little tingle and is direct current not an alternating current (AC) which if handled improperly will cause your heart to stop. Remenber it's not the voltage that kills, it's the amount of amperage. (12VDC 3A -- AC Adapter) vs. (12VDC 700A -- Car Battery) Car battery wins !!! You can weld metal with a car battery but not with the AC adapter. Rule of thumb, You can always under supply the amperage just not over supply it except with fuses. Fuses were designed to limit the amount of amperage that the circuit can handle. Putting a smaller amperage fuse might get by for awhile,but will blow instantly during a power spike. Replacing with a higer amperage fuse will not allow the fuse to blow and cause the circuitry to overload and cause a fire. (Bad !!!!! Do not ever do this).
Hopes this helps.
