I have an LED wall that has a resolution of 3072X1408. It is currently being fed by 2 NovaPro wall processors from a Christie Spyder. It is using the DVI inputs on each, over 10BaseT for transport at 1536x1408 per side. Since this processor also has 3G SDI inputs, I wanted to run the copper to each, and eliminate the DVI extenders. However, I can't get a signal to them. Will 3G recognize a format with over 1080 vertical lines? I understand that there are specific formats related to 3G SDI, but the data being passed seems well within the limits. Any ideas?
