Just as soon as all this is released....heck the HDMI 2.0 protocol will be out. 1.4a is limited on Hz (3840×2160 (4K Ultra HD) at 24 Hz/25 Hz/30 Hz or 4096×2160 at 24 Hz).
The Haswell chipset in the NP-H1 is limited to 24Hz.
....the 2.0 will go up to 60Hz.
These things get dated so fast......the limitations of the tegra 4 and whether it can capitalize on the new specs....I don't know...
