I finally solved the input lag!!!!

First of all I should have said that I apologize for my English.
Yesterday my air conditioner broke down, so I moved my entire setup to my brother's room to use his. I was playing The First Descendant for hours via wi-fi, when I tried to connect ethernet I felt a shock in my fingers, I took a multimeter and measured the voltage between the case of my PC and the neutral of the plug (my house does not have a ground wire) and discovered that I had 6 volts on the case and about 18 volts on the backplate. I unplugged all the peripherals one by one until I found the culprit, the HDMI cable.
I unplugged the HDMI and the case voltage disappeared, I measured the HDMI voltage with neutral and the result was 0v, so I thought the problem came directly from the monitor.
After so many things I tried, the solution was to eliminate the ground pin from the power cord of my monitor, that eliminated the voltage that HDMI was transmitting to my case, I eliminated that weird feeling of the mouse changing throughout the day and my 60Hz looks smoother and clearer!
The question is, why would the ground pin cause problems in a socket where there is no ground wire connected? My house has a TN-C system, where the neutral works as protection. I have a dedicated grounded outlet in my room, but that never solved my problems; anyway, I'll get another power cord and record everything mentioned above. I really hope this helps more people, it's been 4 years since I got excited playing multiplayer titles.
