LCD monitors and external power supply

[Jan Alter]

I'm noticing some LCD monitors are now being made with external power
supplies; meaning they have the voltage transformer on the line cord. Other
than misplacing these cords when moving the monitor from one location to
another, can you thaink of any disadvantage, or advantage, to using monitors
with this configuration?

Thanks,

Yes...
o SMPS tend to be a point of failure
---- so you can just replace the external PSU brick vs the monitor
---- at least, it is easier to get a replacement on Ebay or such like
o Many such monitors use a 12V supply
---- which is also what PC PSUs output
---- so you can power say a LAN-Switch, KVM & Monitor off your PC
o SMPS tend to be quite chunky re minimum size / form-factor
---- externalising the SMPS allows a (very) flat LCD monitor

If the LCD monitor is to be flat-mounted to wall or such, low profile counts.
