Just a quick question. Is there a simple way to adjust the contrast on a Christie 2215. About half way through the life of its first lamp and the picture seems a bit washed out. Thanks!

No, and that is on purpose on a Digital Cinema projector!

Probably the picture looks washed out because the projector does not compensate for the lamp ageing.

Has the LiteLOC been enabled? What was the light level when the lamp was installed? Did you begin with 14fL or did you begin with something less for any reason? (How big is your screen?)

Do you align the lamp regularly?
