Hello, i have some problems with reflection in my render.
When i use resolution (2400x1880px) i can see all reflection right, but if i increase resolution like to (3000x2200px) its all starts to look blurry, and not glossy.
Can someone explain how does it work.

Can you attach the images with an issue and a screenshot of your material tree? Without this, it's hard to tell what's going on, could be texture filtering issue, could be something else.
