Mine is new as of last Christmas, and it does that. It's not "blur"... it's "bleed". The colors are there, and as they move, it takes time for the old color to fade and the new one to appear. That's the refresh time.
It's a problem with LCDs.
The good news is that you won't notice it after a few months. You'll acclimate to the condition. If you ever go back to CRT and then back to your LCD, you'll have to reacclimate.
