I'm very interested in this monitor too. I don't think they actually demonstrated the monitor at CES 2017, but here is the only info I found:

"Best Display: Samsung UH750 31.5″

We’ve always been impressed by the quality of Samsung displays, but the consumer electronics giant is really turning it up a notch for 2017. The Samsung UH750 is a great example. Available in both 28- and 31.5-inch variants, this Quantum Dot display provides a 4K UHD (3840 x 2160) resolution, 4ms response time, and AMD FreeSync capabilities for the best possible performance."
