New 100b - horizontal lines in lcd, noisy darks?

Well I just opened up my new dvx-100b. I've shot with the 100a before, so it's not a new experience.

But I have noticed some tiny lines running horizontally through the lcd. They don't look like digital artifacts, more like tv fuzz or gain lines. You can see them better when I point the camera at a dark area, or tilt the viewfinder. Is this normal?

Another problem I've noticed is a lot of noise when I point the camera at dark areas - mainly the dark blue walls of my room. Seems like the kind of noise I've noticed when shooting dark blues with gl-2's - sort of a red fuzz.

Anyone out there know if these are problems? Is anything wrong with my camera or lcd? If not, will the lines record to tape? And is there anything I can do to mitigate the noise?

Thanks so much!
 
Are you on scene file 1-4, which are interlaced? Try F5 or F6, which are progressive. Noise can be from gain, from certain gamma curves, detail levels, coring, etc. I found mine quite noisy by default, but much better with detail levels turned down, and coring can help even further.
 
Most cameras can't handle extreme dark areas & show grain as a result of noise. Perhaps you can reduce the detail level & V detail level by 1 or 2 values & increase the detail coring, which effectively tries to remove the graininess as a result of noise. Setting the detail level & V detail level too high with over amplify the noise & grain in the picture. But there's a trade-off between sharpness & a less noisy image. The more you increase the detail coring, the softer the image wil be, meaning that the edges in the subject will not appear as sharp as say if you increase both the detail level & V detail level & decrease the detail coring.
 
I actually know exactly what you're talking about, and like you, I also have an 100A that does not do this. In my experience, it does NOT record it to the tape, so it appears to be just the LCD. I don't know how to get rid of it, so I've just learned to get used to it. For what it's worth, the 100B, in my opinion, is quite a bit better in dealing with noise than the 100A, so even though the LCD might not convey it, you will see when you sit down to edit, especially if you have to shoot in a lot of of low lit situations. Hitting on what the posters above me have said, I generally like to run both the detail and v details levels in the negative (usually -7), with detail coring always at 0. I've found that this keeps what I'm focused on nice and sharp while the background is smooth and the whole picture has less noise. It also makes it look more filmlike with the default lens.
