So we now find Ultra-HD TVs 40 "to 700, here an offer of a monitor 31.5" to more than double ... "The Digital" indicate that this monitor was the first Ultra-HD monitor to arrive on the French market during the summer of 2013. Those who want to learn a little more, can read the article about it. I summarize; average ergonomics, poor reactivity as well as the color rendering (Delta E = 3.9) if you are using Photoshop. Rest two positives: a nice brightness and wide viewing angle.
My advice; wait for lower prices you see on 4K TVs (which is not complete) are spreading to monitors.
