Someone gave me an HP 2311x Monitor (a new model) missing the external switching power supply. I'd like to replace it with a generic (due to the high cost of purchasing it from HP), but all I can find out is the power consumption of the monitor (33w).

I have Googled this every way I can think of, but can't find the DC output voltage spec. Even HP couldn't tell me.

Does anyone have an idea how I can find this power supply output voltage?

Thanks...

The power supply is 12 volt, 3.33A. What came with mine is a LiteOn Model PA-1041-0

Thank you very much Jeff. Can I assume that the center pin is + ?

Sorry, I forgot to mention that. The center is "+" and the outside is "-"

Thanks so much Jeff. This is perfect. I've had this question posted for some time now, and was about to give up on getting the info. You've been very helpful.

Happy New Year...
