So, this is my current result with 1800 color panels.
I'm using a gamma of 2.2, which is close to the original gamma.
I'm doing better, but still could improve substantially.
Before I start doing longer runs with more color panels, I thought I would check to see if I can improve my technique and or settings.
When I First started, I was having a lot of trouble with posterising at very dark levels. I was able to mostly eliminate this by increasing the low-level sample time to 2 seconds (up to 10 cd), and setting the black level to 0.
currently the color response and accuracy is good, and much better than before the calibration. skin tones are improved. However, my grayscales are not all gray, and have some small banding visible in test patterns. I also see occasional banding in light blue sky
I have been using user-defined ABL patterns to compensate for the plasma's unusual response. I've been setting them to roughly 18, 18 for size and average intensity.
at one point, I tried to do a 1D LUT first, and although this improved the grayscale and Gamma tracking, it caused an overall reduction of intensity of roughly 10%. Also, it seemed that this one the LUT was acting across all six storage areas in the box.
so, I have various questions:
Is it correct to set the black level to 0, or should I use the measured black level (0.017 with ABL patterns)? There is also a checkbox to use the 0 black level with the auto measure. How should this be set?
Is there a way to use the 1-D LUT without losing so much intensity?
Is there another way to improve my grayscale performance and reduce banding?
I assume that I need to recalibrate my TV inside Calman using the current set up, but the last time I tried this things got worse.
