So I adjusted my pot last night, but I'm not sure if there was an improvement or not. I watched Moon to test the luminance, but it was also the first time watching the movie. Regardless, I was only really looking at the black bars, which are universal in luminance for movies. I do have an i1 LT, but I'm in the Yukon where we currently have 24hrs of daylight, and making any luminance measurements would be pointless. I can get the room very dim, but not pitch black. I'll have to wait until August to take any accurate measurements.
I'll report back tonight after I'm done watching some more material and looking at more blank screens. Note that my luminance level was/is at 0.012ftL, so if I went to, say, 0.009ftL, the changes might not be easy to discern. Also, maybe the new voltage will settle in, or maybe I'll burn the house down. Who knows. In the name of science, at least... kinda.
