Hello,

I don't believe this question falls under LDO support unless you are seeing something specifically related to the LDO. Are you using some sort of EVM or is that a board that you designed?

Regards,

Nick

Hello User,

The focal range of the DLP2021-Q1 EVM is between 850 - 1150 mm.

Can you please take a look or send us a picture of the lens cavity at the front of the projector? The blur might be cased by a lens has shifted.

It should look like this, whereby a lens ring is glued on the exterior to keep optics in place:

Regards,

Lori
