what is the size of the panel master ivan?
It's a 56" pro/industrial screen used for design applications, master joko. The problem with these older pro implementations is that they run many cables (the screen is cut up to 4 areas, so the computer may see it as 4 monitors). The drivers would have to tell the OS to span those areas to let the screen work as a single monitor (like how Eyefinity works now).
That part is now greatly simplified with standalone devices and graphics adapters supporting 4k using a single HDMI connection. Unfortunately, HDMI 1.4a 4K is limited to a maximum of 30p so that probably means that we won't get fluid motion without motion interpolation. Maybe the next version of HDMI will have a provision for 4K 3D and higher frame rates.
I hope HEVC would get wide acceptance soon, as this may make 4k data more accessible.
