HD350 - Calibrated but need help with gamma curve!

post #1 of 3
Thread Starter 
Heya all.

Ive been calibrating my JVC HD350 and everything is getting close regarding colour/greyscale/bright/cont but when looking at the gamma graph it seems too high at 20% (around 2.5) and moves on an almost linear downward gradient to end up too low (at around 1.7) by 90% white.

What control needs to be adjusted to flatten the gradient of the gamma more evenly across the board?

Any help would be greatly appreciated

You should use the gamma equalizer of the HD350. But it's a little bit tricky to use is correctly.

Thanks for the reply Nudg.

I managed to get it tracking close to 2.2 all the way up, but to do so I had to put the Lens apertur on 3 and reduce the contrast heavily.
Everything is reading pretty close to correct, but I now have quite a low FtL, reading, around 10.

Looks ok to my eyes, perhaps a little washed out as I had to reduce the colour significantly to compensate for the HD350's incessant need to oversaturate green and blue.

I have cleaned the lenses after reading about the fogging issue on these projectors, and I'm sitting about 4m away and throwing onto a 110" screen.
Cant seem to get the screen any brighter though - maybe I need a new lamp!

One powerball and Ill be buying a Lumagen Radiance!
