    Hello

    Firstly, thanks for the great software. I’ve been using for a while now but am still not certain I calibrate with the correct settings. I use the Office & Web (D65 2.2) defaults.

    I have a Benq EW3270U monitor (99% Adobe RGB, 95% DCI-P3). On the displayspecifications website, it states that it’s a W-LED. Do I select ‘LCD White LED’ in the instrument mode or do I just leave it on ‘LCD Generic’.

    I’ve imported colorimeter corrections from the Spyder5 software.

    Thanks.

    Also, do I need to change the correction settings in the software? It’s currently on ‘Auto (None)’.

    I have a Benq EW3270U monitor (99% Adobe RGB, 95% DCI-P3).

    If that monitor has those specs it should be one of those widegamuts WLED PFS or close relative. Spyder4/5 bundled corrections does not suport that backlight, the closest one whould be “Widegamut LED, RGB LED” or something like that.
    Device its not very accurate so you may need to fix whitepoint visually.

    There are four options of ‘WLED PFS’ settings but three have IPS next to them. There is also a ‘LCD PFS Phosphor WLED family’ setting. Shall I try that? My monitor is some variety of VA panel.

    It’s all very confusing.

    Anyway, I’ve decided to give it an overnight run in LCD White LED mode.

    I think I’ve previously used both LCD (generic) and LCD White LED in the past without noticing a huge difference between them.

    There’s a CCSS correction file for that panel (same as the AOC U3277PWQU both use the M315DJJ-K30 panel) in the displaycal database here: https://colorimetercorrections.displaycal.net/hash/5776c08dba92a3dc7e10267f9304d1da/BenQ%20EW3270U%20%28spectraval%201511%29.ccss?download=1

    I gave it a run overnight and things appear to be OK. Blacks look especially inky.

    99.9% sRGB, 91.2% Adobe RGB and 90.2% DCI P3.

    Thanks for that A.ces. Are those correction files not specific to each colorimeter/instrument? I wouldn’t have the first idea how to use a CCSS file anyway.

    Hmm unsure how good the ccss file is for the spyder5, If you can I would recommend purchasing either the i1d3 pro, or the less expensive but around 2x slower i1d3 studio, the spyder5 isn’t particularly good especially in the near black regions where it struggles compared to the xrite.

    I think I’ll leave it for the time being.

    I’ve just compared pre-calibration results with calibration results.

    Uncalibrated:

    17:26:09,907 Setting up the instrument
    17:26:09,907 Instrument Type: Datacolor Spyder5
    17:26:09,907 Serial Number: 50062660
    17:26:09,907 Hardware version: 0x0a0f
    17:26:09,907 Uncalibrated response:
    17:26:09,907 Black level = 0.0578 cd/m^2
    17:26:09,907 50% level = 23.34 cd/m^2
    17:26:09,907 White level = 101.25 cd/m^2
    17:26:09,907 Aprox. gamma = 2.12
    17:26:09,907 Contrast ratio = 1753:1
    17:26:09,907 White chromaticity coordinates 0.3111, 0.3280
    17:26:09,907 White Correlated Color Temperature = 6600K, DE 2K to locus = 5.0
    17:26:09,907 White Correlated Daylight Temperature = 6603K, DE 2K to locus = 0.4
    17:26:09,907 White Visual Color Temperature = 6416K, DE 2K to locus = 4.8
    17:26:09,907 White Visual Daylight Temperature = 6590K, DE 2K to locus = 0.4
    17:26:09,907 Effective Video LUT entry depth seems to be 8 bits

    Calibrated:

    17:10:53,874 Setting up the instrument
    17:10:53,874 Instrument Type: Datacolor Spyder5
    17:10:53,874 Serial Number: 50062660
    17:10:53,874 Hardware version: 0x0a0f
    17:10:53,874 Current calibration response:
    17:10:53,874 Black level = 0.0579 cd/m^2
    17:10:53,874 50% level = 22.00 cd/m^2
    17:10:53,874 White level = 100.48 cd/m^2
    17:10:53,874 Aprox. gamma = 2.19
    17:10:53,874 Contrast ratio = 1735:1
    17:10:53,874 White chromaticity coordinates 0.3123, 0.3280
    17:10:53,874 White Correlated Color Temperature = 6531K, DE 2K to locus = 4.2
    17:10:53,874 White Correlated Daylight Temperature = 6534K, DE 2K to locus = 0.6
    17:10:53,874 White Visual Color Temperature = 6380K, DE 2K to locus = 4.0
    17:10:53,874 White Visual Daylight Temperature = 6554K, DE 2K to locus = 0.6

    Any comments would be appreciated as I’m not sure how to read or compare these results.

    Also, why does it say Effective Video LUT entry depth seems to be 8 bits in the uncalibrated report?

    Fiinally, contrast ratio seems low – 1735:1 calibrated and 1753:1 un-calibrated. Specs say its contrast ratio is 3000:1. Mind you, it also says 95% DCI-P3.

    With a i1d3  contrast ratio would be around 2850-3100, and dci-p3 around 94.5% like my panel, also remember to set the display to 10 bit in the GPU control panel settingsz and do a restart of the pc.

    Yeah, it would seem my Spyder5 Express is very limited. I might well sell and put the money towards a i1Display.

    It was already set to 10bit in my nVidia settings.

    Thanks for the help.

    Hmm weird it reports 10/12 bit video LUT for me
