I'm looking to have a workstation with three to four monitors in an office that has borderline cooling capability in summer. These LCDs would be for a developer, and I'd like to find units that have low power usage in normal mode (meaning fully on, without any attached USB or speakers working).
The assumption is that the great majority of the wattage of an LCD translates into heat.
Is there enough variability for me to be able to make a difference?
