Hi guys,
we use double sized images so they display crisp and nice on smartphones. However, one client has embed text into images and we started noticing some blurriness on desktop. The images embed text won't be ever that sharp as live text but we would like to bring it as close as possible.

I found this but it doesn't help:

I tried both:
-ms-interpolation-mode: bicubic !important;
-ms-interpolation-mode: nearest-neighbor;

The bluriness remains.

I hard coded only the height on the images.

Any idea what else to try? Thanks, any input appreciated.
