Did you leave the EyeOnePro attached to the monitor for ONE hour before
making the measurements?
Because of thermochrism effects (EyeOnePro's don't have Peltier-cooled CCD
like more expensive spectroradiometers), their response when measuring at
the edge of their sensitivity threshold are heavily influenced by their
internal temperature I am told. Leaving them on the monitor for ONE hour
before helps minimize this effect.
