I see there are quite a few who have asked about the RS232 protocol or at least clicked "I have the same issue" - I have emailed Monoprice 2 to 3 times over the past month to ask for the Protocol and have yet to hear from them. Has anyone found the protocol and if not shouldn't Monoprice take any reference to RS232 off of this listing?
This multi-view is easy to use and has very simple set-up. I plugged in HDMI cables and was working in no time. That being said, it adds an input label with resolution information over each source, and has white lines dividing the sources in the various multi-view modes. My use case is for client-facing digital signage, so this unit did not fit my needs. It is best used for production monitoring and applications where that extra information is not a problem.
