Is your monitor in this list by any chance?

Comparison chart - CNET Reviews

Even if not, you can see that most 19 in monitors are between 20 and 40 watts of real measured power usage... THe only monitors that hit 100+ watts are the huge 27-30 inch variety.

Where did you get the 1.2 amp figure from? It is 240V X 1.2A= 288W. There should be, if no sticker, some raised specs numbers on your monitor power brick on on the back of the monitor.

Another thing to consider is that inside these devices is a transformer which converts the actual volts to something MUCH lower, say, 12V or 36V.
I wouldn't stress over it.

Well as I said before, those ratings for V and A on the outside are not for what your thinking they are for. Most likely they are mainly for consideration of the gauge of wire to use for the power cord and for instances where multiples are hooked up to a single power circuit and safety code requires not overloading the wiring. SO they are WAY cautiously rated. They state that the max V can be 230 and the max Amps can be 1.2 Not even that both would ever be used at the same time.

The fact that the V is stepped down interally means nothing in this case. In fact if it's a CFL LCD then some of the voltage is stepped up by 20-30 times. It doesn't change the fact that externally, on the mains, those are the max usage ratings. Tag does not reflect max A on any internal individual circuit, only on the main power cord.

Bottom line, the external tag is not meaningful for calculating how much power it will use in daily use. Especially when you factor in personal monitor brightness preferences. You need a watt meter or to search on line for someone else who has used a watt meter for you (Such as that PC magazine article I linked too).

And if you think that was hard, try calculating the energy usage of your desktop with it's 12 different components in it Especially with video cards and CPUs now constantly changing their clocks on demand from second to second.
