Question about CSL HDMI cable 2.0b - 4k Ultra HD 2160p - 3D Ready - High Speed - 3 x shielded - HDMI 2.0b 2.0a 2.0

Dear Galaxus, what is correct now, is 2160p supported as in the title or a maximum of 1080p as in the description? I ordered the thing by title because I need 2160p and have now cancelled again because I'm not sure if it works. When you cancel, you'll probably make a fuss again because the stuff comes from Germany. That's really annoying.
