Hi narikin,
sorry for the long delay, I have been out of town for some days. HDMI is not a standard it seems, Zacuto just released the firmware update, now it is possible to use the Gratical with the IQ3100. 100% is 1 to1 for the HDMI signal, which is about 1080x1920 and not the genuine 11608 x 8708, so you get much less detail. The VF is fine in bright sunshine and the monitor has about 5,2 Million pixels and a great picture quality. Until now I found no way to get liveview on the back and HDMI out at the same time - maybe someone has a solution?
Regards
Wolfgang
