[EMI] 1500mV When computer is running!!!

Separate area for niche lag issues including unexpected causes and/or electromagnetic interference (ECC = retransmits = lag). Interference (EMI, EMF) of all kinds (wired, wireless, external, internal, environment, bad component) can cause error-correction latencies like a bad modem connection. Troubleshooting may require university degree. Your lag issue is likely not EMI. Please read this before entering sub-forum.

one person sent me a filter on x2 capacitors, and I was able to reduce the amount of mv from 1700-1850 to 500mv, with the PC on, but it did not affect anything at all.

I tried with EMI metter, my computer has 1700 mV when turned on, if not turned on. 90-100mV values in all sockets of house... what u recommend guys?

Fixed!!!!!!!!!!!!!!!!!!, no mor mV with this setup:

Now its like only 45mV with this setup (one GreenWave filter too connected to the Anti EMI Power Strip.... Will see if this fix totally this worldwide problem or is not related to this EMI...

This kind of measurement does not mean anything. It's too generic.
Greenwave is a joke.

Why not??? explain, i changed from 1700mV on line to 50mV...

the frequencies that your tester sees have nothing to do with our problem. The only place where you might be able to hear a difference is sound and image.

As the thread says, this EMI is causing desync and mouse lagg on several users here. In my case i tried 2 different houses, different computers, software, and 2 different ISP, tried with Wifi and Ethernet and 5G on Mobile too. Tried with a EcoFlow Delta Pro offgrid too...
The only reason i think it can cause is this EMI higher than normal (25mV or less).

1 week trying 1 filter GreenWave with this: https://www.amazon.es/dp/B09S64J8Y7?ref ... asin_title. Computer, Screen and router connected to this and GreenWave filter too is in.

EMI Metter now says 50-60mV. And its the first time i can see literally something close to 100% no input lag feeling!. Without the GreenWave filter i had 150-200mV, Now its better in all ways but filter didnt solved at 100%, its a way way better now... I probably buy some filters more to test try low mV under 25.

The EMI filter GreenWave didnt act instantly, it took like 3 to 5 days to react to electricity situation and started working good.
