OBS or other capture software loses signal after standing from the gas chair

Hi,
I have a strange issue.
My camera SONY a6400 loses signal to the OBS Studio every time I stand up from the gas gaming chair.

I'm familiar with the EMI effect this chairs release but the thing that is bothering me is that after losing the signal, the camera still operates and there is a picture on the camera display.

Fixing this is either turning the camera off/on or change input of the camera in the obs source to SDI then back to HDMI and the signal is back.

I have tried everything. Changed all cables connecting the camera to the capture card.
Changed the battery. This effect happens when powering with a battery dummy from SONY and powering over USB. Same.

The pc is powered over UPS and the grounding is confirmed.
The capture card is Black Magic Decklink 4K but the effect occurs for Elgato HD60 S+ also.

Any... absolutely any suggestions are greatly appreciated.

Standard chair with lift that going up/down. It works on gas. Every gaming chair has gas in it, thats how they work.

Ohhhh ok. Now I see what you mean. Yes I do have a gaming chair too, but I didn't know mine as gas in it as well. I didn't even notice that. I thought one has gas in it.

Better shielded cables is the only real way to prevent this. Whether the device properly re-syncs after losing signal is entirely up to the device and not OBS.

I managed to isolate (and maybe fix the issue). I added Ferrite core (Ferrite bead) to both ends of the hdmi cable and the issue is gone.
I will test it and will write back for changes.
tnx
