DLP2000: Keep the micromirrors in the fixed position

Part Number: DLP2000
Other Parts Discussed in Thread: DLPDLCR2000EVM

Tool/software:

We have one DLPDLCR2000EVM and want to configure it for static image output. Could you give some help? Thanks.

1. We can communicate with the EVM with one USB to I2C tool, and can change the value of the registers, such as input source 0x0B, input resoultion 0x0C, and so on.
2. Disable the Red and Blue LEDs, leaving only the Green LED enabled, 0x16 register set to 0x0000002
3. Select the internal solid green test pattern, 0x11 register set to 0x00000003
4. Set the current of Red and Blue LEDs to 0, 0x12 and 0x14 register, set to 0x000003FF
5. Disable the WPC function, 0xB5 register set to 0x00000000.

In this case, we record the screen with the phone in the proferssional record mode, and can see the flip. Why? Should the micromirrors keep in the fixed position without any chagnes?

And, it is very strange that we can see one different color stripe in the video. It seems the Red and Blue LED are enable. Could you help to check the reason?
