Part Number: SN65DSI84

When I use SN65DSI84 outputs to LCD, the image outputs well but the black color region looks wrong like this.

A part of black region display red. The image is static. Would you please suggest how to debug this? Thank you.

Hello Hunter Cai,

Can you enable the internal pattern mode and send a picture?
I need to understand your configuration, please download our DSI Tuner to configure the device and send the .dsi file (export it from the tool) or send screenshots of the tool.

Regards

Hello Joel Jimenez0,
The internal pattern mode does not contain black color, but our problem is black color ,so the internal test mode is nomal .
Can we see the black color in the internal test mode?

Thanks.

Hello zero,

No, it is only one test (color bar) in the device.

Seems to be caused by the GPU video format. Could you share details on your DSI8x configuration? Please, export a .dsi for DSI Tuner based on your settings, and share it along with the panel's spec.
