Derek Smith has already left a teaser in his thread, but we are targeting July 1, give or take, to nail down v2.0. We will have full interoperability with ANY VERSION OF SPYDER2. However, I do still strongly recommend using either the STV or S2PRO, though (most people will want the "improved" sensor). However, from a grayscale standpoint, the differences won't matter. No more having to transcribe numbers, and no real risk of Colorvision being able to change a window or font and break the functionality. I will, of course, be supporting it fully elsewhere (announcement when it comes), to the extent my day job allows me. Yes, it will be a commercial product, so this is about the last I will say on the subject here.
Looking over my final calibration results, the 20 IRE window throws a wrench into an otherwise nearly perfect calibration. Both the x and y data from the xyY meter vary 0.003 after the 20 IRE mark, but at the mark, the data jumps .17 in x, and .12 in y. The color temperature also dropped nearly 1000 points below standard. Maybe its a bad sensor, and I should return it for an exchange since all of the other points seem to fall into place.
With the black level you have, I would be concerned about ALL of the measurements if the sensor were bad. To even start worrying about low-light accuracy issues, you need to be <1.0cd/m^2, which your 0 and 10 meaurement qualify, but your 20 does not. Are you running the STV? If so, have you increased the exposure time for these measurements?
I've attached the basic relative RGB graph to show the spike at 20, along with the Gamma Curve. I also thought it was noteworthy to supply the DeltaE vs D65 to further show how large this odd jump is.RGB graph/dataGamma graphDeltaE
Bill, I really appreciate your input so far, and if I have stepped over that thin line I was tight rope walking before, please just pm me and I can let you stay focused on more pertinent topics.
In looking at your graphs, and with you having said that you have to make some pretty significant changes to the green brightness to get it to move, I am still hung up on either a display limitation or ambient light pollution.
If I look at what the guys at Secrets got for the Sceptre 37", your results aren't out of line:http://www.hometheaterhifi.com/volum...05-part-2.html
Looking at what Sony LCD review I could find, I'm still seeing something similar:http://hometheatermag.com/lcds/106sony/index2.html
Of course, the latter only gives us color temp and gamut, so it is much harder to see what's going on there.
Checking a few WSR reviews gives me also adds some evidence to the thought that what you have may be a good calibration for a direct view LCD (a 37" Sharp had a dE of 8 at 20% and 34 at 10% after calibration
). If we can't nail down the ambient light pollution issue...
