Other differences. I notice in your preferences, you are using auto luminance. That may be doing some automatic backlight control. I have this off. You are using a targeted contrast as well. I am using monitor default.
The auto luminance results from targeting a numerical value instead of setting it with the slider, IIRC. Are you saying that you have targets like "140" and don't show auto-luminance?
I originally used "monitor default" contrast, I set it to 500 to see if that helped anything when I was getting low 200s at first. It's clearly not even making 500 so I wouldn't think that was lowering it but I'll set it back to default for my next run.
Colorcomp. I started with it off, because I wanted max contrast. I was going to use it off and see if I noticed anything that needed compensation. I didn't so I kept it off.
I have the exact same vintage of monitor as you D2, 2008/06.
Well, so much for any of those theories. I have toggled colorcomp just to see what it was doing, and I feel it is removing some blotchiness. I will play with it when I have a chance (maybe later tonight).
Your curves are significantly different than mine. It looks like your uncalibrated setting was already matching the calibrated line almost perfectly requiring almost no correction. Mine diverges as the you go up the range. Requiring the correction line to drop below the 1:1 slope to compensate.
But yours is oddly perfect except at the black end of the scale where mine does nothing, your correction line is clearly indicating a pull up on the blacks?? Wierd. It is almost as if you specified you wanted a .35 black and it is pulling the LUTs up to comply.
"Oddly perfect". Go figure. As far as I know I have completely disabled the video card LUT modifications which were being applied for my CRT (not that I'd expect it's needs to match uncal'ed 2490 needs). All of the profiles in Vista colour control show NEC settings from SVII. I have to admit I'm a Vista WCS N00b. I think everything is right in there and I know that SVII goes and sets any system color control up properly after finishing a calibration.
On pulling up the black, that's exactly what I think is going on but I have no idea why. I also don't know what's going on with "oddly perfect" but I'm curious. When I run a cal I see it retargeting the whitepoint color balance so I know it isn't actually perfect...
I guess at this point I should just do another round of factory resets followed by a recal with some changes to the options? Do you know a way to change the default expansion to "ASPECT" for all modes? Sometimes I let the panel do some scaling for certain applications and it defaults to FULL which bothers me.
Thanks again,
