I'll probably set everything on all 3 of my XB270HUs when they arrive to 50%, and then adjust the settings for each one individually according to my Spyder4Pro.
Colorimeters make a tremendous difference in color accuracy and I would neve:thumb:r own another monitor that wasn't adjusted by one. I couldn't believe how off my Shimians were before I calibrated them...just worlds apart in terms of gamma/color reproduction. Not only that, but it's awesome that the Spyder software will automatically apply saved calibration settings per-monitor if a game or program randomly resets the calibration settings.
I have an i1 Display Pro, I like it more than the Spyder 4. The Spyders are quite slow and I must say the Spyder software is a bit too simplified (I own a Spyder as well). The i1 Display Pro software will also lock the GPU LUT for each monitor so it doesn't get changed.
While software calibration is great it is no substitute for a good factory calibration.
With a software calibration you are changing the 8 bit values sent to the monitor to adjust the color displayed while with a good factory calibration you can still use the full 8-bit range. If you need to change the color too much with software you often get banding as 8-bit simply isn't enough precision.
I used to generate a profile for absolutely every display I came in contact with but after more experience with different displays I got a bit more relaxed and now I try to tune the OSD options using the meter to get a setting where I do not need to use a profile in Windows. Of course on many monitors I still need a software calibration to get decent results but I am hoping this one will not be one of them. Good settings on the monitor can look better than using a software calibration, depending on how accurate you need the colors and what you have to give up to improve the color accuracy.
Having a meter to adjust R, G, B, and examine the effect of changing brightness and contrast is excellent but don't assume a profile will always improve things in all ways. I use colorHCFR to examine the effects of changing settings and applying a profile.
Both Sypder and i1 Displays Pro calibrate for graphic design workflows and do not have enough options so I tend to use Argyllcms (open source) as I am calibrating for games and movies, not graphic design. It always takes me some tinkering to find good settings for a new display. Argyll can also generate a 3DLUT for madVR which offers a much better calibration than the simple 3 1DLUTs of a Windows profile.
If the XB270HU has a 2.4 BT.1886 gamma and <2 deltaE color errors I don't think I will need to use a profile on it. I really want to know how the gamma was calibrated.
