The first OLED monitor for the public was released almost 4-5 years ago, yet prices have remained stagnant for the past years. There has been no price evolution whatsoever. Every year, I consider getting one, but I change my mind when I see that prices have sometimes even increased in the meantime. It seems odd to me. I would expect an increase in production of these panels over such a period.
Are you looking for lower or higher refresh rates?
240hz 4k OLED is probably never gonna come down much in price my friend.
