How many bits are used for the Make Noise Image? I see some banding... Maybe it's my monitor?


It's 8bpc.

One reason that you might see banding is if your monitor supports fewer colors. If that's the problem, adding some noise (as in the attached composition) should help.

To check if you really are getting an 8bpc image, you can open it in an image editing application and check the number of unique colors. For example, in Photoshop, go to Image > Mode > Indexed Color. The maximum unique colors you could see with 8bpc is 256. If you see slightly fewer than that (like 246), it's fine. If you see a lot fewer, there's a problem.
