Part Number: DLP3021LEQ1EVM

I purchased one DLP3021LEQ1EVM.

I turned it on, but the demo image only appears like this.
Please tell me how to improve it.

The settings are as below
・The Operating Mode Switch setting is Local Host Control.
(S1-A:Off, S1-B:Off)

- LED status is Blue=Off, Amber=Off, Green=On.

- Each LED inside seems to be lit.

- If you look closely, it looks like a racing car is running.

Hello User,

Is this the projected image/video when you first received the DLP3021LEQ1EVM? Have you modified the EVM?

It would be good if you can re-programming the EVM by following the instructions mentioned in Section 5.1.7 of the DLP3021LEQ1EVM User's guide.

One step back, when you use the composer project from the DLP3021LEQ1EVM product page, please use integer numbers for the R/G/B Duty Cycles in the Sequence Set page and build the project. The default image/video in Local Host mode is race car.

Regards,

Lori

Hello

This is the image/video projected when you first received your DLP3021LEQ1EVM.
EVM has not changed.

Best regards,

Hello user,

I haven't hear back from you for a while. My suggestion is re-flashing the EVM by following the instructions. The ghost image artifact of the field lens optics cannot be removed from the existing optical design as I mentioned in the E2E (https://e2e.ti.com/support/dlp-products-group/dlp/f/dlp-products-forum/1335547/dlp2021leq1evm-projection-display).

I will close this thread. Please submit a new E2E post if you have other questions.

Regards,

Lori
