With your K10A, just measure on/off contrast – without dynamic iris – over time. All the VW1100’s I have measured have a native contrast in the area 7-8000:1 brand new. After 4-500 hours, the measure less than 3500:1, and “black” measures a lot higher than the projector did new. A linear gamma is also impossible unless you hock up a LUT-box or some sort of videoEQ
The VW300/500 have lower on/off contrast, but measure the same raise in black level as the VW1000/1100 over time.
By the way, I also use the Klein K10A. Actually two of them, just to always be able to confirm “suspicious readings”. Use my PR670 for profiling.
