C.1 How to calibrate
General
Barco recommends to always calibrate the projector within the environment it is to be used. This to
compensate for screen type, coating, lens and other environmental factors in a multi-channel set-up. For the
reason explained in the Laser pulse calibration section, Barco also recommends calibrating both laser pulsing
and native colors at the same time.
All projectors are calibrated and tested before leaving the Barco factory to ensure build quality and
performance of the product.
Laser pulse calibration
Laser pulsing is a feature of Fx70 that enables the projector to obtain a specific white y coordinate while
keeping the brightness loss to a minimum, and as the brightness loss happens in both white and black also
keeps the contrast at the same level. Using RealColor to do the same will result in additional brightness loss
and lower contrast. The projector SW is tuned to a white y-coordinate of 0.329 for optimal performance but
any desired white y-coordinate can be used.
When adjusting the laser pulse value to obtain the desired white y coordinate, the white x coordinate will also
change accordingly.
Laser pulse calibration must be done before the color calibration.
C.2 Laser pulse calibration
Calibration introduction
If the projector is to be used only on one laser power setting, use this guide for calibration:
1. Allow unit to run for at least 15 minutes to enable stable light output.
2. Select RealColor mode preset: Native. Menu -> Image -> Advanced settings -> Realcolor P7
Image C–1
3. Select desired BrilliantColor mode. Menu -> Image -> Advanced settings -> BrilliantColor
Image C–2
4. Select desired Smear reduction mode Menu -> Image -> Advanced settings -> Smear reduction
