Hi, we are using our custom board using Orin NX, Jetpack version is R3644. And in our DP out we used a mst chip lt8713SX to set one DP out to two HDMI out.

But when we used our board, it seems get some display issue. After boot up, the screen will display several instances of scintillation and screen artifacts before returning to normal.
And the dmesg gets more info below compared with the normal boot up in the same board

[   18.736845] nv_platform 13800000.display: [drm] fb0: nvidia-drmdrmfb frame buffer device

We see similar question in

In this topic, the solution is to update jetpack to R3643.

I dont know our err is as the same as this topic because our jetpack version is more latest than R3643.

Is it the DP to HDMI MST cause this phenomenon?

Thanks

Suggest to use this kind of MST hub which has our validation.

Also, there is nothing much fixed between rel-36.4.3 and rel-36.4.4 in display. If you really want a full set that has display fix, suggest to use rel-36.5.

Okay,
we’ll try rel-36.5 to test.

Thanks
