Hi Peter,
As far as the Ultrascope, I hope that the answer will change by tomorrow... The ultrascope hasn't been updated in a while and cannot receive a 2K signal or even 444 HD signal (although it is 3G, the 3G is only taken advantage of for higher frame rates in HD). It would make sense that they would update it to support the same formats that the Decklink 4K outputs... unless they do, I think the only option would be a dual link > 3G multiplexer and SDI scaler... something to get a support signal to the ultrascope... I've never liked the idea myself. But there is no way to make the outputs on the decklink extreme 3d (or the 4K) output both 3G and Dual-link.
3rd question: In the video monitoring section of the config page, are you always working with the monitor output set to "full-range unscaled values"? If the config monitoring output is set to "legally scaled values" DaVinci will scale the blacks up to 64 and the whites down 940. It defaults to legally scaled values, which is convenient when monitoring with a broadcast monitor but your Barco preset is probably configured to expect full-range values. The Barco preset could also be set to expect legally scaled values, but more likely it would be set that way on the rec. 709 profiles.
