Blurry Texture

I'm adding a wood texture to an object. My file texture is 3000x3000. Rendering a 1920x1080 frame Turned filtering off. Still blurry. Can't see any of the detail in my wood grain. Searched the web but haven't found anything helpful.

depends a little bit on the amount of visible geometry. if you just show, for example, 1/10 of the whole object, then you just get 1/10 of your uv-space (of course, depending on your unwrapping). that would mean, that there are just 3000px * 1/10= 300px * 300px of texture for the special part of geometry -> blurry
