SN65DSI84: Question for SN65DSI84 output LCD image incomplete issue

Part Number: SN65DSI84
Other Parts Discussed in Thread: DSI-TUNER

Hi Experts,

Our customer is using SN65DSI84 to drive a LVDS panel, but we are facing the output image is incomplete issue as below picture. We checked the MIPI input clock and LVDS output clock without issues. According to the panel vendor, they can not provide the Sync delay, H sync, V sync, HBP, VBP, HFP and VFP parameters, I'm not sure if it is related to these parameters. If panel vendor can not provide them, may I know how to set these values?

BTW, we checked the test pattern which works fine with no issues displaying on the panel.

Thanks.

    Hi Jacky,

    It looks like half of the display is missing. Is this for single DSI to dual LVDS? Have they made sure to ensure that the horizontal parameters on the DSI side (Hactive, HBP, HFP, Hsync) are double that of LVDS side? Please enter the settings in the DSI-Tuner and share the .dsi file here. 

    Regards,

    I.K.
