What's different in Samsung 2232BW+?

I've read the reviews for the Samsung 2232BW monitor, but I see Best Buy now list a new variant: the 2232BW+.

Does anyone know what features are different in the + version?

I did a web search, but not even Samsung lists a + variant for this monitor.

Thanks for your attention!

The contrast ratio is 8000:1 2232bw+ vs 3000:1 2232bw. Don't really know if that will make any difference. Samsung website doesn't even mention the 2232bw+.
