TFP401A: Movable pictures having glitch with black line on the left of the screen

Poh Kok Keng

Part Number: TFP401A

Dear Sir/Madam,

I am using the TFP401A for DVI to LVDS bridge conversion as per block here.

I am having an issue to have the picture glitch on the left side of the screen for the movable photoes. Video is output from the Android platform in Rasberry-Pi.

You can see when the Webpage is moving up and down, the left side of the screen like have a picture glitch with black line. What could be the issue to this? could it be some setting in TFP401A or this is display driver related? any suggestion?

Issue highlighted in Yellow below.

Best regards,

Kpk

Hi Kpk,

Have you checked to see if you have mapped the bits to the correct channels? Can you share your schematic and panel datasheet so I can check? You can email them to i-anyiam@ti.com if you do not want to share them on this forum.
