Softh is all well and nice but it was made as an add-on hack, while brilliant it's only a workaround to the existing framework. I'm talking about implementing it natively for the cards, drivers-wise.
I was attempting to agree with you. I was simply pointing out that SoftTH is a nice proof of concept that shows triple-screen spanning is fully possible.
And lastly, try reading a reply with all the posts that came before it, I clearly meant for NVIDIA to put their software where their mouth is, not some 3rd party app.
You might want to "try reading a reply with all the posts that came before it" yourself.
There's always the possibility of Nvidia and ATi implementing a proper span mode that can be used across two cards (and three monitors), which would make both the TH2G and SoftTH redundant.
