A grounded neutral is key!

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.

A grounded neutral is key!

Post by Sirkiwi » 14 Feb 2026, 19:31

Excuse my English

At my house, the neutral is grounded at the base of the meter. An engineer (a friend of my dad's) kindly checked the neutral-to-ground resistance and measured 84 ohms. The solution was to install a grounding rod 2 meters from the existing one, connect them, and the final resistance was 12 ohms.

I play on my Xbox Series S/X with a 1080p 120Hz monitor, and the experience is far superior to what I had on my old PC with an R7 5700X and an RTX 3060.

Before, in games like Fortnite, Halo, and Overwatch, my aim assist was practically nonexistent, and 120Hz felt like 60Hz or less. But now, the aim assist is incredibly sticky all the time, and 120Hz looks so smooth it feels like I'm getting a retinal massage, haha.

My electrical installation does not have a ground connection , it is a pure TN-C with a grounded neutral.

and what about ur computer did u played aswell on it ! and did it change there too

I used to think that my ground was also the problem (80 ohms) , but then i realize i had a generator nearby and i tried offgrid whitch should get rid of the bad ground right ? didnt work for me.

even generator need grounding aswell and it need to be low resistance under 15 ohms

By default, portable power stations like this one have a "floating neutral" or "floating ground". This means that even if you plug your PC into it, there is no physical path to the earth (the actual ground). The electrical potential remains inside the unit.
latency is caused by electromagnetic interference (EMI) or "dirty power" from the lack of a proper earth discharge, the power station's internal inverter can sometimes create its own high-frequency electrical noise, which might even worsen sensitive peripheral lag.
so at the end of the day u have to ground ur unit aswell and make sure resistance is lower or equal 15 OHM

I tested a 600W inverter with a LiFePO4 battery and got good results on my old PC, but it's necessary to ground the battery's negative terminal and one of the inverter's outputs to create a neutral and 0V reference point. Otherwise, it would be a floating system, as mentioned earlier, and the filtered power from the switched-mode power supplies would remain in the casings.

You can also opt for a hybrid inverter; these already have a ground terminal and handle all neutral and ground connections internally.

I don't currently own a PC; I sold it because of input lag and decided to buy a console. I can say with certainty that even the Xbox had input lag, which fluctuated throughout the day and improved considerably at night. The monitor's colors would lose intensity, and the graphics would seem to flicker, as if they were poorly scaled. Now my game looks good; everything has true 3D, the image is no longer flat and dull like before, and the colors are vibrant. I had to increase the brightness because the blacks are deeper.

It's hard to explain, but games feel slower. Before, even though my game seemed to be running at 60Hz, the pace felt too fast, and that made me lose track of enemies. Now the game is so smooth that the pace is slower, and I have plenty of time to react and aim.

Nice, can you be more specific about your installation and what you did for that ? thanks

I still think that electricity is actually affecting monitors, not PCs...computers are working perfectly fine even on dirty electricity (because modern quality PSUs have extremely strong filtering), but monitors are fully unprotected and unfiltered, and then bad electricity cause display lag, dull colours, less sharp text, 60hz feeling etc.

Did someone try those wireless portable monitors which run on batteries?
