I'm using a Pi 4 to drive the dashboard display in an experimental race car (showing speedometer, fault lights, etc). The Pi is connected to a display via HDMI. Unfortunately, no matter how we've tried to mount the Pi (vertically, horizontally) and despite our use of a few different enclosures, the micro HDMI on the Pi end always works itself out of the Pi a bit at a time and the display flickers and eventually disconnects.
I've tried multiple HDMI cables and micro-to-full-size HDMI adapters, so I know those aren't the issue. I can also reproduce the issue with a different monitor on the workbench (just by holding the Pi in one hand while gently jiggling the cable).
Any ideas for how to fix this? I've already tried crimping the micro HDMI connector on the Pi tighter, but that was a temporary fix. Has anyone experienced a similar issue before or have any other suggestions? Makes me nostalgic for the security of a screw-in VGA connection!
I'm almost considering cutting an HDMI cable open and soldering the wires directly to the pins on the Pi, but I'm not quite that confident in my surface mount soldering skills and I would like to be able to disconnect the cable if necessary.
Thanks!
