I sold my pc but i will be back and I investigate this problem

And how will you solve anything if the harmonics are coming from the grid, and not from your house? They (electricty provider) won't give a shit if your PCs won't work correclty, they would only intervene if this would be a safety hazard.

And I don't know if you tried, buy my problems are almost fully fixed when there is a big load (like oven, stove, ironing, ...) turned on on the same circuit. I'm still sure its some kind of neutral imbalance and high impendance of wiring when the load is low, not harmonics...do you know how good the filters against harmonics are in modern good quality PSUs? They are not just power boxes, they have all kind of complex active filters, it is not possible that a little bit of harmonics would fuck up our PCs like that, unless the values of harmonics are really way above normal.

Bro my electrical installation is fucked up so hard that we have only 6kW for our house and provider don’t want make it higher because we have old electrical installation. So if I don’t check it first, I can’t go further if I don’t rewire my house- first reason is safety(because house can burn basically if something will go very wrong) and then is gaming. Lightning bulb in toilet is running out of life slowly, in my parents room lightning bulbs are burning very fast.
Also my family living next to me can sending us higher harmonics because we are living in semi-detached house. I don’t know… first thing is to rewire house because it can be really dangerous for our livings, if it will not work? I will be sad but happy my family is safe.
Monitors doesn’t have filters like PSUs, am I wrong? Then you connect monitor directly to GPU / CPU and… huh

Did someone try with enterprise-level business monitors from quality brands (Dell, Benq etc.)? Those monitors are supposed to have a much better and robust internal filtering than "gaming" monitors, because they are used in offices with 100+ monitors/PCs connected to the same building grid with a lot of switch noise, and also in industrial complexes where the electricity might be very dirty and they still need to use monitors, not to mention hospitals etc.

Of course, as a trade-off, those monitors would have higher response time than "gaming" monitors, but this doesnt really matter, 1ms resposne time is just a marketing gimmick unless you have 1,000€+ OLED displays... 144Hz 6ms response time enterprise monitors might work much, much better for us with crap electricity than those low response high refresh rate gaming monitors, they 100% have weaker filtering and are unstable with overdrive to reach those speeds (more electricity drawn).

do you have a link to one or a name? ill test one

Literally any "enterprise" monitor from BENQ or Dell, it doesn't matter which one as long as its not some "gaming" model, and it need to have internal power supply, not external adapter a.k.a power brick...Dell UltraSharp series maybe? They are very expensive, but should have robust electronics inside.

Even some cheaper Dell models for 200€ may be good, just avoid "gaming", "ultra low response time", "200hz+ refresh rate" etc., for us on crap electricity, a stable 144hz industrial monitor with 5 ms response time should work the best. And you won't even notice a difference in resposne time anyway, all measuring are just marketing tricks with max overdrive and gray-to-gray method, so obviously they would get 1 ms in those conditions, but in real life the response time on many "gaming" monitors is still above 4 ms.
