Done on gamma mode 4 and RGB values set to (50,48,53). You can check the contrast ratio by obtaining a measurement report (for me it ended up at 992:1 after calibration) After finishing it will generate an ICC profile and prompt you to use the included profile loader. It will first ask you to adjust the RGB values on the OSD while it does repeated whitepoint measurements until you reach 6500K. Click "Calibrate & profile" and follow the onscreen prompt Open the settings dropdown list and select "Office & Web (D65, Gamma 2.2)" Under Display & instrument tab: load the correction downloaded earlier (this only applies for colormunki display and i1Display Pro users) Next, calibrate with Displa圜AL using these settings: Assuming you have a colormunki display or an i1Display Pro, head over to the colorimeter corrections database and download the 34GK950F correction.ĮDIT: A 27GL850 specific correction is now available in the link above! There are no corrections available yet for the 27GL850, so I had to use the closest one I could find which is for the LG 34GK950F, a panel with a similar lg nano IPS backlight. This is where a colorimeter and Displa圜AL come in.Ī colorimeter correction is needed for wide gamut monitors to ensure proper colors post calibration. The second problem is the whitepoint now measures at 6300K and looks too greenish. Mode 4 measured gamma 2.3 (and actually looks washed out) - I calibrated using this mode Mode 3 measured gamma 2.5 (colors look darker than they should) First the gamma curves are all whack on these modes and need to be corrected: If you change it to any other gamma mode, you will notice right away the image is brighter, and no, this isn't just different gamma at play, I have measured a max brightness of around 360 nits with a contrast of 870:1 on default gamma mode 2, and measured 430 nits with a contrast of 1060:1 on every other gamma mode. While that setting has perfect gamma 2.2 tracking, the whitepoint is bluish and the contrast is low. The thing is, the low contrast is only on the default OSD "gamma 2" setting. PremierColour is a pile of poo, and best not used anyway it creates inaccurate absolute-colorimetric profiles that don't work with most software.Figured I'd post this for people who aren't happy with the ~800:1 contrast ratio of the monitor and want to get closer to the typical 1000:1 of IPS panels.įor myself 800:1 vs 1000:1 is not as noticeable as the VERY blue whitepoint (7200K) out of the box, and adjusting the RGB values to bring the whitepoint to 6500K results in further loss of contrast so, here we go. If it does, you need to remove it or disable it (disable its service and disable its startup entry) or it will mess up any other profile creation. I don't know if the 9570 comes with PremierColor. sRGB uses a TRC which is similar to a gamma 2.2 curve, but not identical at the black end. Note that the gamma is nothing to do with the colour space. However, that can normally be done only with the monitor maker's proprietary software, as the APIs to load and control the internal LUTs are not normally public. For those monitors (many Eizo, NEC, some Dell etc) the colour space can be calibrated. That is, if the colour gamut were the same as Adobe RGB, it could emulate sRGB as that's entirely within Adobe RGB. Some monitors have hardware 3G LUTs that allow the monitor to emulate any colour space that is entirely within its native colour gamut. Displaycal doesn't allow you to calibrate to a particular colour space the monitor's colour space is what it is. It's a while since I used Display Cal, but I suggest you set it to calibrate/profile to the monitor's native colour space, which is almost certainly the default. That has a gamut approximately the same as Adobe RGB bit not identical. I think the 9570 uses a similar screen to the 9560, which I have (the 4K screen). But there is no option for Adobe RGB and from what I understand, my laptop's screen is beyond Gamma 2.2 which is basically sRGB right?Īny help greatly appreciated, it's weirdly complex, I thought calibration would be a standard colour that everything tries to get as close to as possible. Specifically the Tone Curve option: Gamma 2.2 / As measured / L* / sRGB etc etc. But now I have a laptop with a screen with a wider colour range I want to be sure I've set up Display Cal correctly before hand. I have used it before with default settings on a previous laptop. I have a Dell XPS 15 9570, and want to calibrate the screen using my Spyder 5 and Display Cal.
