In Practice
Let's start with the negative points. Video is clearly not the best attribute of this unit. Apart from the video noise, the biggest issue is the poor range of viewing angles. Of course, the panels are not meant for that. Gaming is not bad with good latency and vibrant colors. Still, the high black level is not ideal for ambience games like Doom 3 for example. Then again, the panels are not really designed for gamers either.
The use of this device in an office environment is what's really interesting, and that's actually where a dual screen makes perfect sense. It's a cheap way to get extra screen space and resolution. When you consider that a 1600x1200 panel will cost you $700, the DS1700 offers 2560x1024 for less than $1100. The adjustments are good enough to let you get a comfortable ergonomic work position, and you can also rotate the screens to get portrait mode view if you need to (though in that respect, the poor viewing angles of TN panels are not ideal.) You will also have to lower the brightness quite a bit to get less eye stress.
Conclusion
Based on what I have seen, the DS1700 is a good productivity screen. Its build quality is high and it features good ergonomics. As the video is rather poor and it lacks 5000K color temperature, I am afraid this monitor will be mostly used for monitoring task likes lab equipment, finance graphs, audio studio wave monitoring and so forth, because that's where its qualities make the most sense.
Should you choose the DS1700 or two separate monitors? Well, that's another story. Sure two separate screens like the Samsung 710T will give you a thinner bezel. It will be cheaper too. But the DS1700 still has the integrated display solution card to play and with it you are sure to get matched displays and not devices that may be very different.
