I know old thread, I'm new to the forum, but...I'm setting up my optoma HD20 and noticed that extreme reds have noise or static. I'm not really great on adjusting picture quality to begin with, but am just wondering if this is due to the projector, the HDMI cable, or the receiver. Is it that red is over boosted and I should lower it. There are 2 settings for red on the projector "Red Gain" and "Red Bias". What's the diff? Thanx for any help!
I'm having the same problem with my HD67. Is there any fix to it?
