|

Hi,
I have been having lots of problems my JVC X35 projector using Chromapure 125p autocalibration, a Lumagen Radiance mini 3D and an Eyeone Display 3 pro.
It seems to work fine to measure and get decent pre-calibration results. However, when running the autocal the end results gets all wacky with dE´s and gamma completely off the charts and a completely unwatchable picture. It starts out OK but every iterative step seem to put the calibration more and more out of wack.
I have been trying both to measure from the lens and from the screen, with gamma 2.2 and BT.1886, all producing weird, unusable results.
When I first got the equipment 18 months ago I had problems with the 2.2 gamma, but the BT.1886 worked fine, and it was the one I wanted, so I never bothered to look into it further. However, now nothing works anymore and I cant calibrate my projector!
I really hope someone here can help me. Thanks in advance!
Cheers, Ted

I need two things to troubleshoot this.
1. A calibration report for a 125-pt session.
2. Copy/paste all of the text in the activity window into an e-mail and send that as well.

it's better to use BT.1886 or gamma 2.2 ?
if you choose BT.1886 in chromapure, which mode you select in your video projector (you don"t have BT1886 in JVC)
