Monitor goes black randomly connected via 4-in-1 adapter and HDMI

Hello,

I'm afraid I don't have a brand or model specifically. If you take a cable which is supposed to work for high speed communication, you can hope it is of better quality.

You can test for ESD by using the old way of lighting the gas hob: a piezzo gas lighter.
A ferrite choke on the cable should also improve immunity as it is a filter.

Kind regards,
Alban
