Those dc-connectors are actually standardized, you cannot, supposedly, connect the wrong voltage to the monitor.
Current is a whole different question though.

Over current is Ok but if under current won't be enough to drive monitor!
Voltage has got to be the same though, if over will run but not for long!, and if under likely won't run at all!

Depends. Should there not be voltage regulators? If so, 'over' is quite normal to let the regulators work without too much noise and a volt more is less critical than a volt less[^].

Most important is to prevent the smoke from escaping. Devices work on smoke, when the smoke comes out, they quit.
If you can keep your head while those about you are losing theirs, perhaps you don't understand the situation.

Yeah, that's pretty much the science I was using here.
Oh, well, it works.

Think of overclocking your computer. A volt or two may not make a difference but the extra voltage is converted to heat and it stresses the components.
If you buy a Wall Wart rated at, and I forget what the OPs requirements were but it converts and regulates the voltage from 11V, or 220V in other countries to 12v.
If you want to further regulate it you can use a DC-DC Digital Display Step Down Boost Buck Board Converter Power Module | eBay[^] , there are cheaper models but this one has a display.

Digital. Works or doesn't. If the power supply is too weak, the current will be too high, the voltage will drop off and the device will not work. The fuse may or may not save the power supply, depending how high the current gets.

Yes I know, I meant that the current available is not standardized by the contacts.

A man of the law by the name of Ohm wants to see it otherwise.

Not necessarily. Most are positive center, negative outer connector. But not all.

That's why I wrote "Supposedly", just because there is a standard doesn't mean people are following it.
And to complicate things further there are more than one standard, the original EIAJ standard actually specifies the outer barrel as positive and the inner pin negative, while the later IEC standard doesn't specify polarity as far as I know.

Great info. Thanks very much.

The user manual (found by googling your monitor and "power requirements") indicates Output voltage/current Output: 12VDC/3.33A for the power supply.

Oh man! I am so lame that I didn't find that.

I'm going to have to go with the squirrel that looks like it yelling out "STOP!!!!"
if (Object.DividedByZero == true) { Universe.Implode(); }

I pictured it screaming: DON'T!

That works too

Nice find.

TY so many excellent photos.
The very first one - bite your bum. An expression I have used many times takes on a whole new meaning.
