DLP4620SQ1EVM: Request for DLP4620 Composer project

Kim Yangrae
Prodigy 70 points
Part Number: DLP4620SQ1EVM

Tool/software:

I am trying to drive the DMD using the DLP4620EVM. The DLP Composer project I previously received only allows resolution changes to 1220x610 or 1358x566. My current issue is that I want to display a completely filled screen using all the pixels of the DLP4620. Upon checking the datasheet, it states that for resolutions of 960x480 and 1920x960, the DMD diamond mirrors used can support 960x960. However, neither of these options can be selected in the composer at the moment.
For this reason, please provide a project file in which the resolutions of 960x480, 1220x610, and 1358x566 can be selected.

Furthermore, I want to use a resolution of 1920x960 with the DLP4620EVM system. How can I achieve this?

    Hello Kim,

    Thank you for reaching out to us.

    You can find all software development tools for DLP4620SQ1EVM here.

    There are two composer reference projects:

    1. DLPC230_HUD_p46_nonDDS_VSP.xproj - Supports input resolutions 960x960 and 960x480 for DLP4620S HUD DMD (diamond sampling is not required).
    2. DLPC230_HUD_p46_DDS_VSP.xproj - Supports input resolutions 1358x566 and 1220x610 for DLP4620S HUD DMD (diamond sampling is required).

    For effective resolution of 1920x960, you would need to pre-process the video content at the front-end before feeding to the DLPC23x. You can then select the 960x960 configuration in the Composer project. Check out 'HUD Image Processing' for detailed explanation.

    Thank you,

    Regards,
