Blurred images in chrome

Hello,

I'm having a problem and i can't find a fix.

I have an image in container with width: 100%.

Even if the image is bigger than the container the image is still blurry in Chrome.

In Safari i fixed it with "image-rendering: -webkit-optimize-contrast;" but i can't find a fix for Chrome.

Here you can see the problem (look at MacBook Air text): http://newadw.yup.ro/projects/cos-technics

The image is 1147px width and the container is 1140px (so the image is resized with css from 1147 to 1140).

If i remove the width:100% and height: auto from css it will looks ok and crisp like original image (but without responsive).

Anyone had this problem before?
