DLP3010EVM-LC: DLP3010EVM-LC: DLPC3478+DLPA2005, change the projected picture size.

Part Number: DLP3010EVM-LC

Hello 

In the process of burning pictures and projecting, I encountered the following problems. I need to burn the original size of the picture is 1280*720P, but I want to change its size to 720*720P when projecting.

Therefore, I performed the parameter modification operation on the Display Setting interface of the DLP EVM GUI.

The specific settings are as follows. Interestingly, the size of the projection image built into the DLP EVM GUI does change, but when I burn the image I need into it and project it, the size does not change. Hope to get your help.

Grateful

Lee

    Hello Lee,

    Welcome to the E2E forum and thank you for your interest in DLP® technology!

    For splash screens to be loaded properly, they must follow a specific procedure of commands. This is shown in Table 10 of the DLPC3478 Software Programmer's Guide.

    To update the image size please do the following:

    1. Write desired image crop (opcode 0x10), display size (0x12), and image orientation (0x14)
    2. Select Splash screen as input (0x05)
    3. Write Splash Screen Execute (0x35)

    Please let us know if this resolves your issue, and thank you for your business.

    Kindly,

    Austin
