Lighting Conditions For Projectors
The room in which the projected image is being viewed should be as dark as is
practical. Especially during calibration there should be no lights shining on or near the
projection screen. Be sure that no ambient light is shining toward the Spyder sensor.
Screen Saver
Screen Savers and Energy Savers should be turned off before calibration. If the
monitor turns off or dims during the calibration process the process will have to be
repeated. If the monitor goes to sleep and wakes up again during regular use, color
accuracy will be affected until the monitor warms up
