Hello,

I would like to know how the DLP4500 chooses the incoming video that will be projected.

If I am using FDP Link and HDMI as inputs with different videos, how it will choose which to project.

Also, could I manage this choice via I2C?

Helo Diogo,

I believe the video source is chosen through a combination of I2C commands issued via the GUI with assistance from the TFP401 PanelBus IC. You can change the video source via I2C commands issued to the DLPC350 controller. See section 2.3.4 of the DLPC350 programmers guide www.ti.com/.../dlpu010g.pdf for the I2C commands.

Thanks,
Kyle
