Random question, since this is kinda the general thread for projectors. When I calibrate (HCFR) I always turn off all aids, iris, contrast enhancer, etc. A large number of the reviews on my projector (HW65ES) said they use contrast enhancer on low. So I figured maybe I will give it a shot, I noticed when I enable it , it drops my brightness down to the point where the black clipping video on the avs disc (I usually use this to set brightness) is no longer correct (I lose 17 and 18). So I guess my question is, if I want to use the contrast enhancer, should I calibrate with it on so the black clipping video is correct or should I calibrate like normal then enable it even though it obviously drops brightness to low on the clipping sample?
