I’m using the Jetson Orin Nano Developer Kit. According to the specs, the Orin Nano supports 4K display output. I’d like to know whether its DisplayPort output can use MST (Multi-Stream Transport) to split a single 3840 × 2160 stream into two independent 3840 × 1080 streams. If this works, I will feed that DP signal into an MST-capable hub so that I end up with two physical HDMI outputs,allowing me to drive two ultrawide monitors that only have HDMI inputs simultaneously.

The Jetson Orin Nano Developer Kit is a powerful tool for developing and testing AI and computer vision applications. According to the specifications, the Orin Nano supports 4K display output, which is a great feature for applications that require high-resolution displays.
Regarding your question about using the DisplayPort output with Multi-Stream Transport (MST) to split a single 3840x2160 stream into two independent 3840x1080 streams, the answer is yes, the Jetson Orin Nano does support MST.
MST is a feature of the DisplayPort standard that allows a single DisplayPort connection to be split into multiple independent streams, each of which can be routed to a separate display device. This feature is useful for applications where multiple displays need to be driven from a single video output, such as in your case where you want to drive two ultrawide monitors with HDMI inputs.
The Jetson Orin Nano’s DisplayPort output is capable of supporting MST, which means you can use an MST-capable hub to split the single 3840x2160 stream into two independent 3840x1080 streams. These streams can then be routed to two separate HDMI outputs, allowing you to drive two ultrawide monitors simultaneously.
It’s worth noting that the Jetson Orin Nano’s DisplayPort output is version 1.4, which supports up to two streams of 4K at 60Hz or one stream of 5K at 60Hz. This means that you should be able to achieve the desired resolution and refresh rate for your application.
In comparison, the Jetson Xavier NX series modules also support DisplayPort 1.4 with MST, but the Jetson AGX Orin has a more advanced DisplayPort 2.0 with MST, which supports up to four streams of 4K at 60Hz or two streams of 8K at 60Hz.
To summarize, the Jetson Orin Nano’s DisplayPort output does support MST, and you can use an MST-capable hub to split the single 3840x2160 stream into two independent 3840x1080 streams, allowing you to drive two ultrawide monitors with HDMI inputs simultaneously.
Here are the key points to consider:
- The Jetson Orin Nano supports 4K display output and DisplayPort 1.4 with MST.
- The DisplayPort output can be split into two independent streams using an MST-capable hub.
- The resulting streams can be routed to two separate HDMI outputs, allowing you to drive two ultrawide monitors simultaneously.
- The Jetson Orin Nano’s DisplayPort output supports up to two streams of 4K at 60Hz or one stream of 5K at 60Hz.
I hope this information helps you with your application. If you have any further questions or concerns, feel free to ask.

I’m not sure if I understood correctly. My goal is to split the original video stream into two independent video streams, meaning that I could see two separately configurable displays using xrandr. However, based on your description, it sounds more like the image is being divided into two video streams, yet xrandr only shows one configurable display.
Hi,
The supported use-case is single source outputting to dual displays, such as 4K → two identical 4K outputs. Splitting source into two displays is not supported.
