Need advice re power supplies

[samchan]

Hi wonder can anyone help. My monitor need power DC 12V 4.0A external lead, which I have not got, but I have a AC/DC adaptor output : 12V DC 500mA Can I use this one?

Generally monitors use that, including my own, and also every PSU out there

^ Some monitors require 120, or 240 VAC as an input, But some require a AC to DC converter (brick)

If your monitor Requires a "Brick" Power pack: short answer NO you can not use a power pack rated @ 12V/500 mAmps inplace of one rated at 12V/4Amps. It will not power your monitor and the DC output would be very low - You could damage your monitor. Also the brick will Overheat if left attached for very long.

You are kidding, right? You need 4 amps and you only have 1/2 amp and that assumes that the plugs are compatible.
