I have a flat monitor and never used a curved monitor. I read some online reviews that if you are going for a larger monitor then you should go for a curved ultrawide monitor as curved monitors provide an immersive viewing experience. But curved monitors are generally more expensive than flat monitors. Do you have a curved monitor? what was your experience with curved monitors?
