Portsdown 4 and external monitor

Post by IK0YYY » Tue Oct 14, 2025 12:37 pm

Hello everyone,

I have a simple question: is it possible to use an external HDMI monitor together with the standard touch screen monitor to review the monitor output of the Portsdown 4?

Some time ago, Dave replied that it wasn't possible, but I reiterate that this could be an interesting addition, so that I could use the fantastic Portsdown 4 at home too, with a nice 27-inch monitor!
Who knows, maybe I'll be able to convince him to perform a miracle!

Thank you.

Hi Luca

No, you can't use the HDMI output at the same time as the touchscreen (dsi) output.

If you are trying to monitor the test equipment or simple text screens, the web view provides an alternative, but this does not play moving video.

Thanks Dave,
this is something that, once implemented, could really add enormous value.
Think about it.
Thanks for all the updates you provide, see you soon.
