The usage model really depends on you, but I can see how that could be useful for something like video editing where you may want to see more information horizontally (and accurate colors!). Traders could also replace two smaller displays with a single 29” panoramic screens. Since most computers only allow the connection of two displays, this would be a much simpler solution than switching to a quad-output graphics card.
With a resolution of 2560×1080, there are q few competitors already on the market, and although not all of them use such an exquisite IPS display, many users don’t need the high-quality color reproduction either. I have to say though: even if you’re not a designer, IPS is a very nice option to have if you can afford it.
The Lenovo LT2934Z also comes with a KVM switch, which lets you toggle between multiple PCs. This is not a very common option, but it makes sense since the monitor can display two different video inputs side by side, which is idea to control two computers from one monitor.
If you need some video chat capabilities, there is also a 2 Megapixel webcam, integrated speakers (2x3W) and an array of microphones that support noise-cancelling. As it stands, the Lenovo LT2934Z offers a lot more features than most 29-inch monitors, but we will have to see what the price tag is.
