Part Number: DLP670S
Other Parts Discussed in Thread: DLPC900

Tool/software:

Hello, Ti expert!

I asked the question before, that is, I need to use the refresh rate of 15HZ, which has been used stably in the project.
However, several different refresh rates need to be tested and verified, which are 5HZ, 7.5HZ and 10HZ respectively.
Please provide me the EDID file （DLP670S,HDMI）including the above refresh rate, thank you!

    Hello Junfa,

    We have only validated standard frame rates such as 30 Hz and 60 Hz. Please allow me some more time to check if the DLPC900 can operate at the lower frame rates.

    Thank you,

    Regards,
    Aishwarya

    Hello Junfa,

    Unfortunately, DLPC900 does not lock to the source with refresh rates less than 10Hz. I will mark this thread as resolved since we cannot provide a solution right now.

    Thank you,

    Regards,
    Aishwarya

    Hello Aishwarya

    Let me ask again, can 10Hz be supported?

    Hello Junfa,

    Please check with this EDID file. Contains video timings for 10Hz, 15Hz and 30Hz.
