Yes. I'm using a digital connector, DVI. That's what I should be using, right?, to take advantage of the display? I have the option to use a VGA connection, but I assumed DVI = better.
Digital is sharper, but often has fewer controls, most prefer it, but analog has its adherents.
The Optical info report says uncalibrated white was 217. The calibrated white is 216. Uncalibrated black was .4 and calibrated black is .34. Doesn't mention what the units of measure are.
Candelas per meter squared.
If I reset the display to factory defaults and profile, it is substantially brighter than when I launch Optical. Once Optical is running, the screen gets darker and contrastier. So Optical is doing something even before I click the "calibrate" button. I assume it's imposing the settings I selected for white point and gamma?
Yes, its a bit different in the newer Spyder2PRO, in OptiCAL you are seeing settings applied in real time.
the easiest trick to distinguish the two in most cases is to lower the control while the on-screen menu is up; if the whole screen, on-screen menu and all, darkens, its probably a backlight control.
So I gather that's a good thing in that I can dim the display without eating into the 256 levels per channel in the video card? Do I have that right?
Yup...
The Spyder/PreCal manual says that LCDs can be anywhere from 150 to 300 luminance, and the Optical instructions says that the suggested white luminance should end up around 200. So at 216, I wasn't too far off. It's just that the darker tones were too dark in photos I was familiar with.
Again, Spyder2PRO is more advanced about this, but if you run your monitor bright, and your ambient light not so bright, you may well see shadow detail differently than desired...
Based upon CDTobie's and other's recommendations, here's what I'm thinking I should try next:
- dim brightness buttons to lowest level and brighten my workspace some
Good starting point
- use 'normal' sRGB preset and don't fool with PreCal or the individual RGB sliders for now (and if I later decide to try it, don't use the individual RGB sliders to dim the display)
Right...
- Set Optical for native whitespace and 2.2 gamma
Bingo...
