No, the TH2G is very picky concerning the horizontal timing values - as far as I
could figure it out, the box will only do the splitting when very specific horizontal
timing values are supplied. The box seems to be tolerant concerning the vertical
timings and the pixel clock - but so far, I only tried variants that are only off by a few
percent from the default settings. And to my knowledge, vertical splitting is not
possible at all!

It might be possible to generate at 3840x2400 signal on just one DVI output which
the TH2G might splitt into 2x 1920x2400, but this would be just around 25Hz.

However, I'm wondering if in your special case you could get away without *any*
of the TH2Gs by using a simple twinview setup (off on GPU): each of two DVI
outputs generate a 1920x2400 signal at 48 Hz and the two outputs are then
combined into a single screen with twinview.

I have attached an xorg.conf that might work for you.
