I'm not a 100% sure on this, but I think that the Snell and Wilcox Advisor (I believe that's the model) cna do that. I know that it has the capability of splitting the signal for use on a video wall, but it might also be able to do it on the same display device. The downside: price. It is very expensive. I don't know of any reasonable prices units that can do that.
Thanks!
