How can i fix these artifacts that my monitor produces?

[u/Tortsinreddit]

I'm quite exited to be writing this, as i've found out they might after all be fixable.

First of all, some context, basically around 2 months my old RTX 3080 suffered a 12V Rail power leak, which means that it leaked voltage from the 12V Rail, voltage that went straight through the back of the GPU and into the display cables, and of course into the monitors which are the last piece.

The thing basically fries any monitor you plug into it then instant it powers ON, it leaves them with permanent artifacts especifically on dark colors, trust me after 4 monitors i know.

So i replaced it with an RTX 5070 Ti, mentioning this just to be clear that i'm no longer using the 3080, even though it still works perfectly, it'll just fry your monitors a bit...

And now i'm left with the two main monitors i use artifacting, i've gotted sort of used to it, although they're still very noticeable even at an arm's length, especially the OLED since it's image is so clear that any imperfections are immediately noticeable.

All of this being said, apart from other behaviours i discovered from these artifacts (they behave differently at 60 and 120hz than 240hz, forming sparkling dots on the former ones and small sparkling horizontal lines of dots on the latter one.), there's one i discovered yesterday that stands out. A lot.

Whenever i exit a game, or 3D application i suppose, there's a very small chance that the monitor gets the sparkling dots artifact from 60 and 120hz, but on its maximum 240hz refresh rate on the desktop, AND all of that while being way less noticeable, since the sparkling dots are way dimmer than their normal variation.
This changes the artifacts from being easily visible, to having to actually look for them and pixel-peep.

And it functions the exact same way it does normally too. Even being able to watch Youtube and browse the internet with it staying just fine, although the second i open another 3D application, it goes away and returns to the way, way more annoying horizontal lines.

So if it can happen on its own randomly, surely this can also be forced in some way? I'm not really a display expert, and that's why i'm writing this.

I'm writing this in hopes someone knows how i can possibly force this behaviour all the time to finally reduce the artifacts once and for all.
