Interesting news seem like such chairs actually absorb electric field from the environment and pass to the user,
affecting the screen as well. I wonder if the computer are affected too ?

ang mo usually use carpet. They put the PC on the floor is it?

This happens with even Secretlab chairs and some monitors. I had this problem everytime I get off my chair the screen goes blank for a sec and comes back on. But since changing monitor, it hasn't done this before. Something to do with some static discharge when the hydraulic renounces when you get off.

IMHO.
Likely is user fault. Why user?
Static needs to be generated and usually is by movement.
The movement can only be from the user.
Of course the "right environment" is a contributing factor - carpet, aircon, etc
Like someone say, to avoid static, dun wear clothes.

The scenario is similar to static build up in cars of yesteryears.
The seats are fabric, and usually the same for the driver's clothes.
The driver gets "charged" while driving the vehicle.
When the driver gets out of the vehicle, there is a possibility to "discharge" to the metal car body.
Ouch !

P.S. I stand to be corrected.

Our body can absorb electric field from the environment and therefore produce electro static even without clothes.
To prevent this. Wear emf shield clothes as shown below.

Car absorb the most amount of electric field from environment which produce electric static. Ground the internal of the car properly with link shown below. https://www.aliexpress.com/item/100...207530794!sea!SG!0&curPageLogUid=vRTOiFrUI6ds

And a good emf shield device is for best protection.

IMHO.
The T-Shirt is not real world practice.
The car grounding, is totally unrelated. The electrostatic discharge occurs between human and the car.

I think our knowledges need to be update. Even cars need to be fully grounded. See below link.

My knowledge of such straps is that they have been around for ages.
In Singapore, I have seen them on tankers transporting petroleum and flammables.
I believe it is a SCDF requirement and AFAIK, this is current no such requirement for passenger cars.

The static has got nothing to do with the vehicle per se. The charge is generated between the human and car seat. Locally such straps is unlikely to make sense to passenger cars because we are tropical and higher humidity.

P.S. However, I stand to be corrected.

I just want to enjoy having little discussion.
Are you referring to truck/railcar grounding for petroleum/flammable truck ? It's not the same as the link provided.
They are for passenger car, ground from exhaust pipe to road. Exhaust pipe are bolted to bottom of a car and engine.
So it remove any electric static charge from car body and engine compartment.
It the car that's moving and protect driver from environmental electric field which casus electric static charge.
I wonder why would a driver produce so much electric static charge unless they have been expose to high amount of electric field. High amount of electric static charges can cause explosion. I saw it on documentry before
Back when i was younger, i did some grounding on motorbike and car. It does improve electrical performance too.
Cars/motorbike rely on electricity and petrol to move.

No idea what you actually want to discuss.
I suggest you re-read my post again.

Someone posted take a yellow green earth wire and ground it to the table, this method will discharge any static electricity.

Someone doing a lot of rubbing with their feet off the ground?

May I know which chair you are using now?

I am looking for computer chair now while the intermittent black screen really a weire incident

I've been using my Secretlab Omega softweave for almost 2 years now and didn't change it as it feels and looks as good as new.

The problem is most chairs with hydraulic lifters is the static discharge that it creates when you sit down or get up.

I've actually attached some ferrite rings on the display port cable and it reduced the issues when I was using the Samsung G7. But with the LG Oled, I never had this problem. But the ferrite ring has been on my displayport cable since my G7 so maybe that works after all. You're having issue with your monitor which I think is the same one I am using too. So yeah try the ferrite ring and see if it helps. It's a cheap mod before changing your computer chair. Measure the thickness of your HDMI cable so you know roughly which size to get.

Many thanks for sharing. Actually I don't have the issue with the black screen, it's just that I am using the dining set chair and very inconvenient to move around since it does not have roller.

I have seems some real case and video shared that some computer chair really does cause the intermittent black screen when the chair moving around even when the user are not sitting on it.

I want to avoid similar incident and was searching for an affordable computer chair for more comfort purpose.

Most of the issues are related to the hydraulic lifters emitting static discharge when sitting or getting off. It doesn't create any issues otherwise. But any chair with hydraulic lifters can potentially create issues.

Many thanks I will take note on this factor when getting the new chair

Amazon.sg has the remastered Aeron for sale at S$1149. This is less than half the price I paid for my Aeron so I would do some due diligence like checking that it is new and not refurb, warranty etc.

It's not happening with my Herman Miller Aeron, and it has never happened with any chair I used. IMO it's just that the POTATO PC is having a problem.
