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.

Hi,

I am also looking to find LCD computer monitors that have an external power supply. We are installing it in a track system where there will be movement back and forth, and for safety reasons we prefer to have low voltage running through the power cable than 120vac.

Could anybody provide a link to such monitors? I have done a search and nothing comes up, and I also checked out the local Fry's and they don't have it either.

Thanks in advance.
