Texture error - polygons outside texture shows black texture


i am new to blender and i have following problem with textures. In one of my projects i would like to reduce size of texture by increasing scale of polygons (however with texture coordinates I have the same effect). When polygons are outside texture in UV Editor i receive black texture. Do you know how can i fix it?

In new blender project with just a cube scaling outside texture in UV editor works great. I only have this problem in one project, have i enable some kind of function?

Best regards,

Check your image texture node if it’s set to repeat.

I had to change this parameter by accident and I would never have thought about it.
Thank you very much.
