Profile Header Image Blurred?

Hi Gliders…

Anyone knows why profile header image blurred (unfocused)?

I used an image with dimensions: 2000px x 200px.

Thanks in advance.

Is it an issue on smaller devices?

No @ThinhDinh. I took a screenshot of above picture on my laptop.

When I use an image on common container, it looks clear. Actually, I redesigned the background image (container) and profile.
