@2X Images Not Showing Up

I'm using iMac, but instead of @2x images, normal images are loading

Why it is happening?

Please make sure that the "HiDPI Displays Support" module is enabled

Also note that you should reupload detailed images:


HiDPI is enabled and Thumbnails set to PNG. Anyway they are not showing

And i tried about 50 times to reupload, nothing changed
