Why aren't there other monitors with Samsungs fast VA panels

[hitishakeys5]

As far as I know the panels themselves are pretty good and issues are mainly due to a lack in QA. They seem to deal with typical VA downsides fairly well 10.0.0.0.1 192.168.1.254.

So why aren't these panels more common but there's a flood of mediocre VA and even more mediocre at best IPS monitors. Is it because Samsung just doesn't sell them to other monitor makers? If so why don't other panel suppliers try to replicate it.
