Simultaneously Use HDMI Native and DSI to HDMI Converted Outputs on Verdin Development Board with Verdin iMX8M Plus Module

I’m working on a project that requires to use two HDMI displays. I was wondering if anyone here has experience or knowledge about using both HDMI native and DSI to HDMI converted outputs simultaneously on this setup.

Specifically, I’d like to have one display connected via the HDMI native port and another through the DSI to HDMI converter. My goal is to extend the visual output to two different HDMI displays for my application.

Has anyone attempted this before, or does anyone know whether it’s possible with the Verdin iMX8M Plus module and the Verdin Development Board? If so, I’d greatly appreciate any insights, tips, or steps to achieve this dual display setup.

Thank you all in advance for your assistance, and I look forward to hearing your thoughts and experiences on this matter!

Greetings @imeshsps,

Using 2 HDMI displays one on native HDMI and one on DS to HDMI should be feasible. Referencing our documentation: Display Output, Resolution and Timings (Linux) | Toradex Developer Center

The DSI interface and HDMI interface use completely different display controllers on the SoC. Therefore there should be no conflict. The only things to remember is to make sure the device tree overlays for native HDMI and DSI to HDMI are enabled on the device.

My goal is to extend the visual output to two different HDMI displays for my application.

As for this point if you are using Weston, then the default behavior should be extending the display output to all displays attached.

Hey @jeremias.tx,

Thanks for your response. Are there any other options you can suggest for using two HDMI ports?

I’m not sure if I understand your question. What do you mean “other options”? For HDMI output on Verdin i.MX8M Plus you either have the native HDMI or DSI to HDMI. Therefore if you need 2 HDMI outputs there’s only really one option. Unless you want to add significant extra hardware on your carrier board or something.

Hey @jeremias.tx ,

I’m considering using Yavia career board for this application. Do you think it will be possible to drive 2 HDMI displays simultaneously with Verdin iMX8M Plus Module?

Well the Yavia board has 2 HDMI interfaces. One is the native HDMI which the Verdin iMX8M Plus does have. The other is an HDMI that is converted from the MIPI DSI interface which all our current verdin modules posses. So yes it should be possible.
