Part Number: SN65DSI84

Hi team,

As DSI84, I have some questions, could you kindly help me? Thanks!

Will DSI84 change blanking parameters in the process from MIPI DSI to LVDS?
Display D.S blanking parameter is as below, if valid resolution is 1920*1080, what is the blanking? 140, 45 or 280, 45? Why?

Please use the DSI Tuner SW to generate the DSI84 register programming value.

1030.DSI Tuner 2.1.zip

Please also see this TI training on how to use the DSI Tuner to program the registers base on the display datasheet, https://training.ti.com/configuring-sn65dsi8x-single-channel-dsi-single-link-lvds-operation.

Can you please share the full display datasheet?

Thanks
