Btw... would it possible to use the monitor as a converter from HDMI to SDI and feed the loop into the Samurai?
The TV Logic VFM-056WP (premium) converts the HDMI signal to HD-SDI. There is no HDMI loop through, just HD-SDI. The monitor is quite good- somewhere I recall it had 768 lines of resolution. You can do a pixel to pixel punch in.
