I recently bought the HP w2228h monitor on the cheap locally. It didn't come with a power cord and I was amazed at the price of the HP 8121-0739 power cord that originally comes with it.
I am not too keen on spending £30 pounds on a power cord - but I know little about power cords and transformers. I spotted a £5 C13 power cord on ebay claiming it can be used for LCD monitors. However, this cord is rated at 250V, 5A.
The HP w2228h manual has this to say about the power cord:
The monitor power supply is provided with Automatic Line Switching (ALS). This feature allows the monitor to operate on input voltages between 100–240Vv, 50/60 Hz, 1.5A.
The power cord set (flexible cord or wall plug) received with the monitor meets the requirements for use in the country/region where you purchased the equipment.
If you need to obtain a power cord for a different country/region, you should purchase a power cord that is approved for use in that country/region.
The power cord must be rated for the product and for the voltage and current marked on the product’s electrical ratings label. The voltage and current rating of the cord should be greater than the voltage and current rating marked on the product. If you have questions about the type of power cord to use, contact your HP-authorized service provider.
However, this specifies a 240V, 1.5A input voltage. I do not know whether the cheap 'alternative' will work. Please advise!
