DLPC350: Discontinuous intensity from DMD device in pattern sequence mode

Part Number: DLPC350
Other Parts Discussed in Thread: DLP4500,

Hi Team,

We would like to ask your help regarding our customer's inquiry below.

I am using a projector that uses a DLPC350 chip to control a DLP4500 0.45 WXGA DMD device. I use the LightCrafter 4500 GUI 4.4.1 software to place the DMD device in pattern sequence mode with the Video Port as the image source. However, when I vary the grayscale of the the projected image, the grayscale-intensity relationship is linear until 50% gray (RGB 128) at which point there is a severe discontinuity where the projector intensity drops significantly. See attached image.

I am working on a project that requires the continuous modulation of individual pixel intensities. How can I access the full intensity spectrum while using pattern sequence mode?
