Nec monitors on Dell site - please explain?

Sorry if this would disappoint, but I’m happy with my Dell monitors :emotion-2:
And none requires any attention from service or forum’s advice.

I was informing myself about the latest Dell monitors and then I’ve found this : http://tinyurl.com/6z8z6sx

Since when is Dell selling Nec monitors? I understand partnership in PCs and supported periphery.
But, I don’t recall ever seeing Nec monitors being sold on Dell sites?

Prior of posting this, I tried to search some explanation within Dell domain, but found nothing that would explain this.  Could someone please explain the nature of this sale?

regards
Mike
