I had the exact same issue, they pretty much said it is what it is. Bottom right corner is just too annoying for me too, it grabs your attention while gaming, watching a movie, browsing or work. For this price I expected much better quality control. The purchase I was most excited about, turned out to be the most disappointing.

What did you do in the end, did you ask for a refund and try again with a different monitor brand? I went with Dell because I know how good their return policy is, and I too expected quality control to be top notch. I don't really want to have to live with this... but I'm not sure I want to hassle of tring to return it etc.

@Sephzer  My return is on hold for other reasons, they haven't said no to the return yet. I'm not sure about their quality control anymore and their tech/service support was horrible, so if I return I will definitely go with another brand. That's my experience anyway, might be different for others.
