Has anything changed lately with madTPG? I use both Calman and LightSpace via a laptop to calibrate my Sony 940E HDR display using madTPG as the pattern generator on my HTPC. With both programs this evening, madTPG would disconnect randomly in the middle of taking reads. My network is solid and did not drop, so i am not sure what is causing this behavior. Being that this behavior is happening with both Calman and Light Space, makes me think the issue is with madTPG. Calman, Light Space and madvr are all on the latest version.
