Header Image is blurred - Upload upscaling to 1200px

Hello Colorlib team,

I use your WordPress Theme Iddly. I noticed a possible bug.

Ask a question about the image upload. When I upload an image (for example, 2000px for the header), this image is scaled down to 1200px. In the theme, however, it appears blurred.

How can I fix this?

Thanks and greetings from Germany

Hello there,

I hope you are having a great day thus far.

Could you please reduce the image to 1200 px and check to see if that newly added image has the same blurring problem?

Best Regards,
Cheers
