Hi TI Team,

Regarding displayport output, can the resolution be customized in rtos driver?

Hi,

I think this resolution should be possible over eDP, can you please try it?

Whats difference between eDP and DP?

From the hardware point ,eDP and DP also use DP0_TX0_P/N、 DP0_TX1_P/N and AUX CH on TDA4VE

So we only modify the video timing in the Dss_dctrlDrvDpStartVideo function?

thanks

Yes, that's correct.

Which SW component are you using? In vision apps, you need to update timing appInit in vision_apps\platform\j721s2\rtos\common\app_init.c file.
