Solved monitor watts

[Wicca]

i have a LCD monitor 19 INCH 1440*900 it does not show the watts but only the amps and voltage is there anyway to find out cause i used the amps by voltage but that could not be right as it would not use 120 watts

Hi Wicca. Watts = Amps times Voltage.

 

[Wicca]

my volt is 100-240v and my amps is A1.2 so 100 mutiply by 1.2 and that give me 120 watts but that can't be right can it ??????????

 

[kado897]

It depends on your mains supply. If it is 100v then you get 120 watts. If it is 240v then you get 288 watts. In truth because of the way these things work then the real wattage is somewhere between the two figures.

how can it be 120 watts but my tv say is uses 50 watts on the back and it has volts of 230 and amps of 1.2amps

 

[kado897]

That seems reasonable for an LCD screen. An LCD TV will be around the 200 watts mark.

it says
19" LCD

17-31 watts

but my tv say is uses 50 watts on the back and it has volts of 230 and amps of 1.2amps

I have a HP2310i LCD monitor that is rated at 56 watts.

My mains voltage is 240v so the current would be Watts/Volts (56/240) i.e. 0.23 amps.

I suspect your current consumption is 0.12 amps, not 1.2 amps.

Chances are the amperage figure on the back is a misprint.

Also, the power rating may be a peak rating instead of a working rating.

Things have obviously improved since my TV was bought. My 32inch LCD TV is rated at 166 watts. I suppose it depends on what the voltage supplied to the screen is not the voltage of your power supply. So the real answer is you can't calculate it. If your manufacturer can't tell you the only way is to measure it. Good luck with that.

it is just my lcd 19 inch is not extremly bright and my 41 inch tv use 160 watts max

 

[Wicca]

also i cannot ask the manufactor as it does not tell me volt and amp is meed up as my tv tells me it is 50 watts and it says 230v and A1.2

 

[kado897]

Have you tried googling the monitor to see if you can find out?

 

[Wicca]

i have tried but it does not tell me the watts

 

[seavixen32]

What is the manufacturer's name?

 

[kado897]

It's a shame. These things are always difficult to find out. You would think in these energy conscious days the it would be a selling point.

it is AOC this is my montior ADVENT MW19E 19"W, Reviews & Price Comparison

Does it come with a power adapter. If so there is usually a sticker on that which gives the output voltage and current in the small print. That will give you a better idea.

 

[Wicca]

no sticker
