Rigol DHO814 HDMI output
(1/1)
Tubeoman:
I recently purchased a Rigol DHO814 oscilloscope and tried to connect my HP Z24i as an external monitor. The cable is a HDMI -> DVI for the input on the monitor (no HDMI input on this monitor).
The Rigol scope will not switch on its HDMI output unless I unplug and replug the cable and then everything is fine, but this will eventually ware out the HDMI connector. It would be much better if there is some menu entry by which I can enable the HDMI output, but I cannot find this menu point - maybe you can.
The DVI connector has a full house of pins and is of high quality.
Do you have any suggestions - thanks.

I see two possible solutions: extension cable or HDMI splitter.

Just to let you know, it seems that the HP Z24i monitor does not communicate properly with the Rigol DHO814 scope on when to switch on the monitor display.
I connected an older Lenovo ThinkVison monitor using the exact same HDMI to DVI cable and this monitor automatically recognizes the signaling and starts as it is supposed to.
I don't know whether it is the Rigol or the HP Z24i that has the problem, but it works now with the Lenovo monitor!

I wonder if a cheap EDID emulator might resolve the problem, eg https://www.amazon.com/dp/B0BR7N9CBS
No idea if that specific one is any good, just a random result to demonstrate. It does somewhat align with your description of the problem, you might not be getting EDID from your monitor.
