I'm new at this but having fun so far;
Finally picked up an Eyeone LT the other day and put my KDFE42A10 through an initial calibration; just did a quick "before" and then tweaked the rgb gains/bias a little to produce an "after," both files attached. My goal was simply to follow the curtpalme.com guide
to get my 30 IRE and 80 IRE rgb levels right on the 6500K spot. As you may see, goal achieved! But looks like I'm nowhere near done yet...
Watched some hi-def Dr. Who afterwards and my initial impression is quite mixed; contrast is *definitely* improved, but actually too high as now the whites are blending together and wayyy too bright. I also perceive a large amount of "blue push," so there's just a kinda blue haze over the entire screen.
Looking over my files, I *think* I'm "running out of red" at the top end. And also my gamma is way too low, running around 1.8-1.9 across the board. I believe this is because I failed to calibrate my contrast and brightness at the beginning; I just jumped right into the r/g/b gains/bias. Another mistake I think I made was to mess with the "green" gains/bias, even though it is recommended not to do so; I did so because on the low end (30 IRE) I couldn't lower my red/blue bias' any further to meet green and I wanted to "push" the green up to compensate.
So tonight I'll do another run and begin with contrast / brightness calibration; my gamma appears to be not quite linear, but if I can bump the 10 IRE up to 2.2 properly, I still think I'll be in better shape to re-adjust my rgb's.
FYI; this Sony is a rear-projection 3-LCD model. It actually had a very acceptable picture to begin with - I just enjoy the process of tweaking it to perfection. Natch.
Oh, P.S.; patterns I'm using are the "AVCHD" from this thread
on a Sony Playstation 3. This is connected via HDMI to my receiver (Sony STR-DG910) which is then HDMI 1.2 out to the TV.
Any suggestions based on my files here much appreciated.Attachment 162945Attachment 162946
