Thanks, I am aware of all of that I've been dong these cals for many moons, the only new part is the alternative meter. It doesn't matter if I do it off of the screen or directly at the lens I get very similar red deficiency and since these lamps a generally red deficient it points me toward the lamp, I just wanted to see if anyone had any other suggestions or can relate to it. If autocal isn't able to boost red enough and cannot even be corrected manually it generally means a new lamp is in order in my experience.just not to get confuse, which ipro are using? is it the i1 display pro?, how are placing the meter during calibration? if u are using i1 display pro. please make sure that the difffuser is in place (ON) and that u are doing the reading in the AOI. mode, at the start up choose a longer maximum integration time, the default is 4 switch it to 6. also choose a qaulity gamma 33 steps.
make sure that u doing the reading from the projector lens with the meter about 3 feet in the front of the peojector lens and leveled up with it, so that the meter is getting the max. reading.
on the x7900 which is the same model i own, i recommend that u turn on the projector for 50-60 min. before u start any calibration , i noticed from measurments that lamp in these projector takes a little bit more time to realy kick in.
finally don't get too much hung up on the generated graph results that u see in the autocal. App.ultimately u want to measure the image that is reflected off your screen, because that is what's your eyes will be seeing, so a measurment off the screen with calm/hcfr. ect. at the end of the session is really recommended.
