    Hi all

    Has anyone calibrated an AOC Q27G2S/EU? Curious as to the results and if anyone knows any settings that will get the best out of this monitor, including ‘Correction’ choice . My initial calibration so far with an i1 Display Pro Plus is getting about 950:1 contrast ratio and to my eyes, the result doesn’t look as good as my previous monitor, AOC 24G2U.

    Self check report enclosed.

    Thanks!

    It should be a WLED backlight type. I would assume “LCD PFS Phosphor WLED IPS” but I could be wrong. Try the 98% Adobe RGB/96% P3 one.

    YouTuber Hardware Unboxed says it’s 95% P3 with his measurement. The AOC website says 110% which is completely misleading.

    Thanks Raj! Why would you assume LCD PFS Phosphor WLED IPS? Is that the most common?

    Is there a website that has any of this info regarding which LEDs / panels monitors use?

    We rely on manufacturer specs, color gamut coverage and maybe third party reviews.

    The spec sheets only ever mention WLED, so that means it could be any of the WLED options. If they mention Quantum Dot, we use the Quantum Dot option instead.

    Since your panel’s a WLED IPS and it has 95% P3 + equally high Adobe RGB, we use the 98% AdobeRGB/96% P3 one.

    Most displays these days (including TVs) are WLED PFS Phosphor. Usually the 93% P3 one is the right one. That’s because most use standard WLED but with the red phosphor to boost reds because that’s what the DCI-P3 (HDR) color space favours. Like for deep red highlights and fire scenes.

    The normal White LED category is there for old monitors only. Only for standard SRGB gamut monitors!!

    For anyone else who has the AOC Q27G2S/EU, these are my post calibration specs / details.
    Settings I chose were Gamma 1, 100 cd/m, 175 test cards, WLED IPS 98% Adobe RGB.
    Gamma setting 1 is the closest to 2.2 at 2.23 so I used this (Gamma setting 2 = 2.04, Gamma setting 3 = 2.44)

    I achieved a contrast ratio of 944:1, 99.9% sRGB, 85.8% Adobe RGB, 92.8% DCI P3.

    Then it is not. More likely to be the lesser WLED PFS 94% P3 or pFS family alone. Depending on ypur i1d3 firmwre it may not noticeable in whiepoint.

    Thanks Vincent! I’ll try both PFS WLED 94% P3 and PFS WLED family and see if I get better results.

    Hi, can you share the Q27G2S profile for DisplayCAL? I bought a monitor and tried to calibrate it myself, but without a calibrator I can’t really adjust it manually. I would be very grateful)

    Hi Kalwant, thanks so much for your ICC profile, I just use it, and have safe me a lot of time. Thanks so much for sharing it.  🙂

    Just keep in mind a shared ICC profile won’t be very accurate. Every unit is different. Same goes for settings

    I’d agree, but if one hasn’t got a calibration device, it’s surely better than nothing or trying to do it manually…..
