So I acquired an NEC PA271Q and a Spectraview II sensor pro. I found the latest update on Sharp's site, version 1.1.44. The menu of the PA271Q is confusing me.
Under picture are 5 choices:
Picture mode, Emulation, 6 axis color trim, picture settings and calibration.
Under picture mode are these options:
Adobe RGB(160nits),eciRGBv2, DCI-P3, Rec709, Rec 2100HLG,Rec2100(PQ)HighBright,LowBlue,Full,DICOM,Programmable,sRGB(80 nits)
Since I want to calibrate this for photo editing in prep for making prints I think I should set it for Adobe RGB (preset #1). There are a bunch of settings I dont really understand
Brightness at 160 (good?)
Black min
Gamma 2.2
White 6500k x 0.313. y 0.329
Red 0.640 0.329
Green 0.210 0.710
Blue 0.150 0.060
But then there is a preset #5 labeled 'Spectraview II'
Brightness 130
Black min
Gamma 2.2
White custom x 0.310 y 0.322
Red x 0.682 y 0.312
Green 0.214 0.727
Blue 0.153 0.041
Are these remaining settings correct?
Then under emulation is
3D LUT emulation off
color vision emulation off
Do these stay off?
Auto brightness off
Uniformity 5
ECO mode off
Calibration
color stabilizer On
metamerism Off
Under Video
Displayport settings 1.2 (not 1.1a)
DP out multistream SST (not MST)
Are these settings correct?
Firmware R1.302
Spectraview engine 5.00
I assume I should warm up the monitor for 30 min, calibrate it and set it to profile #5?
I ran the calibration and it said it created an ICC profile. It also changed the brightness and the white point in the 'Spectraview II' profile. The color offsets remain unchanged.
Brightness 151
Black min
Gamma 2.2
White custom x 0.311 y 0.335
Red x 0.682 y 0.312
Green 0.214 0.727
Blue 0.153 0.041
It also created an ICC profile which I can see in the color management control panel.
Am I done?
I use the following settings to calibrate.
White Point: D65
Gamma: 2.20
Intensity: 90.0
Contrast Ratio: Monitor Default
Color Gamut: Native (Full)
I have the SpectraView II users guide that explains the calibration process. I recently downloaded Spectraview II to a new computer and the guide is in the zip file.
Thank you for your reply. On entering the calibration option, there are 4 function selections
Self calibration, Reset Calibration, Validation and White copy.
Only Self Calibration is selectable
The menu also shows no date for the last calibration
At the bottom it shows MDSVSENSOR3: Connected
Pressing the 'set' key starts the calibration.
The screen shows:
Calibration result: Failed
Measurement data is invalid.
Please confirm sensor placement and measure again
This happens even if I set the profile to full.
This happens even if i max out the luminance to 400
Interestingly, the spectraview software only sees the sensor if it is plugged into one of the blue usb ports and the internal calibrator only sees the sensor if is plugged in to the top usb2 port (as the manual indicates)
Interestingly, the internal calibration can be updated using spectraview.
Entering the menu on the display now shows today's date for the last calibration.
However, the screen fails calibration when trying to use the internal calibration from this menu
I don't have any experience with NEC's self-calibrating monitors. I suggest you talk to the person you bought it from to see if she ever experienced the calibration failure. If there is an issue with the monitor that was not revealed to you, a partial refund might be in order.
Have you done calibration on any monitor before? Are you familiar with the concepts of monitor calibration in general?
If not, then you'll need to learn a bit about what is the purpose of calibration and some of the common parameter values or target values that you have to choose or decide on that you want to calibrate to.
To get the image on the screen to better match a print, one of the key thing is to work in a dim room and set the monitor to a very low brightness, 80-100 cdm. Setting 'white point' to a lower value like D5000 or D5500 to better match the not so 'white' of the paper. Color space is the 'full' gamut of the monitor (best it can do) instead of restricting it to Adobe RGB.
I have the NEC 272W which doesn't have self calibration. I believe you still use the Spectraview II software and the sensor to set the desired calibration target values (brightness, gamut space, white point, etc) and do the initial calibration which saves the calibration values inside the monitor. After that, for follow up calibration using the same target values, you can run the monitors self calibration with the sensor but you no longer need the computer and spectraview software. But you will need the Spectraview to create a new or different calibration target values. I think you can save several different target calibration result in the monitor and switch between them via the front buttons menus.
