scale - retina @2x image not crisp when scaled down on FF / Chrome -


i feel silly posting basic html question, thoroughly stumped. have 100x100 pixel graphic (test@2x.png) serving image , resizing 50x50. should result in crisp image both retina , non-retina screens… not (in chrome , firefox, safari fine).

that same image saved @ 50x50 (not resized css) , original show okay @ 100%, when original 100x100 scaled down choppy.

technically not understand how possible happen. given have retina screen should exact opposite: images @ 100% aren’t quite crisp , 2x images scaled 50% are.

i must have done thousand times before without issue, have idea what’s happening?

screenshot of i’m seeing (imac/retina support, chrome v37): http://i.imgur.com/cs3sjod.png

the answer question idiot... imacs not have retina support. how acknowledged seeing "the exact opposite" of retina screen should (aka: showing non-retina screen) didn't put 2 , 2 together. i'm going go hide now....
