Other Parts Discussed in Thread: DLPC350

Hi,

i would like to  display images on the DLP4500 via HDMI.

But it can not correctly connect with my notebook. ( sometimes it  can connect but sometimes can not  before)

Then I test on the  GUI "LightCrafter4500_v1.2.exe" ,  pattern mode can work  but video can not.

How can i do?

Thank you for your help!

Kind regards,

Vic

    Hi, 

    Welcome to TI E2E forums! Could you kindly flash the EVM with DLPC350 FW v4.1.0 and use LCR4500 GUI v4.0 to operate it? After doing this, kindly try connecting it to an HDMI Source and see if you can see the video in "Video mode". Kindly try with another computer also. If it still fails, kindly let us know if any error is shown, and try to read the source video information by clicking the "Get Video Info" button under the "Video Mode" tab on the LCR4500 GUI v4.0. 
    Hope this helps!

    Thanks & Regards,

    Hirak.

    Hi,

    DLPC350 controller has a firmware flash image that helps control and configure the internal hardware. You can download the latest DLPC350 FW v4.1.0 from here.

    You can download the latest DLPC350 GUI v4.0.0 from here.

    Kindly use the latest GUI to flash the latest FW onto the LCR4500 and try again. 

    Thanks & Regards,

    Hirak.

    Hi , i can use the  GUI to flash the latest FW onto the LCR4500 like this . 

    In video mode-input configuration , all the mode selection could work correctly  except  Parallel RGB.

    So that i can't extend the desktop on my laptop to the projector , how can i do to fix it?

    Thank you!!

    Hi User, 

    We can confirm that the "Parallel RGB" setting works on LCR4500 GUI v4.0.0 and FW v4.1.0, and we are able to display external video using the onboard miniHDMI port on the LCR4500 board.

    Could you kindly try another PC? If external video still doesn't work, there maybe some HW fault on the board. 

    Thanks & Regards,

    Hirak.
