Hey guys, I have a Cine7 with HDFury and GammaX at 1080i. I am using the power supplies. Problem is with gamma correction at full there are these dark lines on the screen. See screenshot below. Is my gammaX defective? These lines go away with the gamma correction turned all the way down, or the GammaX removed from the system.

where do you have the switch set on the side of the GammaX? Do you have the power supplies plugged into the same circuit as the projector?

1) Switch is set to pass. If I remember I had it on INV and the projector wouldn't sync.
2) They are plugged to the same outlet but not same powerstrip.

Thanks!

It looks like a ground loop to me.

Disconnect everything but an bluRay source connected to the Fury and Gamma right under the projector. Disconnect all audio etc from the BR player. See if the lines go away.

Also, try disconnecting the Fury power supply. you only need the GammaX one connected, the power loops through the Gamma to power the Fury. Try each supply to eliminate one of the supplies as a possible issue as well.

Which HD Fury is it? Mine did the same when the image was shifted too far.
