DLP6750Q1EVM Phase Light Modulator control

Hi, 

We recently received a DLP6750Q1EVM Phase Light Modulator. I followed the instruction from user guide as below.

1.  connect the board with 12 V power supply.

2. Connect the mirror bias power (J5 port) with a lab power supply (voltage:1.66volt, Current, 10ma)

3. Connect HDMI with computer 

4. Configured computer video source to output 2560x1600

But, even if I display the 4 bit hologram pattern and illuminate the DLP with laser, there is nothing shown from the DLP. 

I am wondering if there is any missing part in my control process. Please let give me an instruction for how to correctly turn it on. 

Thanks
