Maighstir: While f.lux and Redshift are already mentioned, I feel I should probably inform that both of those modify the image that the computer sends to the monitor, but I would take a look at the settings of the monitor itself first with some test images (99.99% of external monitors have some sort of setting/menu system built-in via buttons/dials on the monitor itself - TVs may or may not have them but rarely as full-featured as monitors, and I have yet to know of a laptop that does).
JDelekto: Will do, not sure if my monitors are that advanced though... Post edited December 18, 2015 by Maighstir
