Images Not Clear On Mobile Device

Hi all,

I know there was a similar topic but I can't find it...

When visiting my site on a mobile device, I've noticed that my images are not sharp and clear as on my desktop.

I'm using the pluging HiDPI and enabled it.

So all my images are schrinked with 50% when uploaded so I already put in images twice as big but stil no good result. I'm using 72dpi resolution on my images.

Any help in the wright direction very appreciated :grin:

Using version 4.3.3
