After many years of search, unlimited efforts and suffering, I came myself to the conclusion that one of the most important factors regarding the reduction of the symptoms is the Graphic Card factor.
I must also notice that after many experiements I felt myself a huge difference using some specific graphic cards which I will mention bellow..
First of all, I have myself till now tried many different graphic cards, not only from Nvidia, but also from Radeon, as well as many integrated graphics (like Intel or Ryzen). Some of the cards were the GTX 1660, GTX 1650, GTX 970, GTX 960, GTX 680 and very old cards like the GT 230 or the Radeon HD 6950 and a couple of other cards as well.
I must say that i felt some noticable difference using older cards pre 2012, like the GT 230 or the Radeon HD6950.
However the difference was quite small.
In addition the GTX 970 and 1660 (claimed from many to be some of the best) did not have any positive results at all…
Then I found out about the memory chip thing…and I realized that both of the above 2 cards had the Hynix Memory chip…Maybe that could be the reason they were not comfortable at all and not the model of the cards?
Therefore I tried buying and experimenting with some Nvidia Graphic Cards with the Samsung memory chip…which I have read in many posts that had very positive results for many members.
Specifically I bought and tried the GTX 960 with Samsung chip, the GTX 680 also with Samsung chip and realized…that all the cards with the Samsung Chip had a HUGE difference in my experience, minimizing extremely my symptoms!!!
This is the reason why I would like to share my personal experience, after suffering for many years and trying unlimited possible solutions ( like screen filters, silver and iron sheets, different operating systems etc etc etc,) from which almost nothing helped enough, except the "old" nvidia graphic cards with a Samsung memory chip!
The difference is significantly big and thus i want to share my experience with all the people suffering from the same or a similar situation.
Finally I would like to request everyone here to post their experience with Graphic Cards writing down also the specific characteristics of the card, if possible, including the memory chip. Other aspects that have significantly improved your are welcome as well.
Thanks a lot everyone and I will be happy to read your experiences.
