I have a UK 240v labeled monitor can this be reconfigured to work on US
voltage without buying a step up transformer?

Study the label on the back very carefully. If it has a specification
on it like "90-240 V 50/60 Hz", then all you should need is a different
power cord (mains lead) for a US socket. If, instead, the specification
says something like "110-120 V / 220-240 V AC" then there is probably a
switch or jumper that needs to be adjusted to make it work. If it's a
switch, sometimes it's accessible from the back panel, and is usually
labeled "110" and "220". If it's a jumper, you'll have to open the
monitor to see it. You might also try dell.com or dell.co.uk and look
at the specifications for _exactly_ your model number.

A local TV shop may be able to help. They should know how to
reconfigure the power supply if it needs it, and they should have a
variable transformer that they can set to 120 V to test with.
