32GS95UE Factory Calibration

[Michael]

I just bought an LG 32GS95UE 32″ W-OLED monitor for general use.  The factory gamma setting (mode 2) is supposed to be 2.2, but, using various gamma test images, it’s closer to 2.4.  The RTings review found the same thing.  If I set the monitor to mode 1, (gamma 2.0), or mode 4 (sRGB),  test images appear about right, at 2.2.  Any reason to choose one over the other, especially regarding any effects this might have on HDR mode?  Are gamma test images to be trusted?

Also, I finally found a driver, with an ICM profile on LG’s Korea site.  Once installed, the monitor does recognize SDR content versus DCI-P3 content and displays each correctly – at least according to wide-gamut.com.  Do ICC/ICM profiles usually cover both DCI-P3 and sRGB gamuts?   If I bought a colorimeter and generated a profile, would it cover both gamuts?

I don’t do color critical work.  I just want my monitor to look reasonably close to accurate.

Test images are inaccurate with display scaling.    Browser must be set 100% size and windows display set to 100% scale and monitor has to be at exact its native resolution.   Funny my screen 4k 3840×2160 and default native.   It’s true resolution is 4096×2160 and passes visual gamma test at that.   Charts show color gamma and white gamma.   Color gamma is not the same as white gamma.   White does not depend on color.

sorry cant be sure with the question.    ICC/ICM profiles do cover both but profiles implies more than 1 profile.   1 profile does 1 color space.  It can not cover 2.

Thanks Ben.  I forgot about the scaling issue.   I’ll retest with scaling at 100% – resolution is already set to the native 2160p.

As to one ICC profile doing one color space, here’s what confuses me…  My current monitor failed the “Take the Test” page on http://www.wide-gamut.com.  That one page has content in both sRGB and DCI-P3.  My monitor displayed all the sRGB content oversaturated.  But once I installed the drivers, which included a single profile in Windows Color Management, my monitor passed the test, displaying both sRGB content and DCI-P3 content correctly on that page.

It knows.   It can make P3 look like SRGB in a color managed app.    The pictures are tagged I think.   Your non driver profile was not correct.   I see on mine only srgb.  HDR is not enabled in Windows.    I think your display might do 3.5 out of 5 on HDR.    Its not 1000nit display they claim its 600 at a 1.5% screen area.    You have to do measurements to see where your colorspace is.  The driver is good if you do not have a calibrator.

You need a profile inspector to see what driver profile is.    Displaycal can view a profile and you can see what its setting the color space to and info about the type of the profile and details on its measurents.   Its not your monitors but its what it is supposed to be.

Thanks!  I leave HDR off in Windows when I’m not using it.  I used Microsoft’s HDR calibration tool, and it came up with 600 in the calibration screens.  HDR looks terrific in games.  As to the gamma, with everything set to 100%, it is high when on the default setting.  Mode 4, which is supposed to be sRGB, looks good on several types of gamma measurement images.  I know it’s not perfect, but I’m not doing color critical work.  It looks good in pictures, videos, programs, etc.  I’d calibrate it just for the fun of it. but I don’t want to spend the money for a decent colorimeter.

Hi Michael, I just got this monitor as well as the MSI 321URX QD-OLED. I am returning the MSI because I cannot live with the purple blacks, reflective coating and color fringing on text (on all QDLED monitors currently), despite having a larger peak brightness in HDR mode. I really want to like the LG 32GS95UV. But I am struggling as well to get wide-gamut.com to (and other similar pages) to recognize the monitors wider P3 gamut.

I also downloaded a driver from the Korean site of LG as you suggested, but still no luck, the monitor is being recognized as an sRGB monitor only, in SDR mode and native Gamer1 profile.

The monitor is being recognized as an HDR monitor when in HDR mode, and also the P3 wide gamut is being recognized, but I want to be able to benefit from the monitors wide P3 gamut while in SDR mode as HDR will be used only occasionally.

As I understand it you are able to get the monitor being recognized as a wide gamut P3 monitor in SDR mode?

And if so what exact driver did you use? Can you post a link?

Thanks,
Ole

Update; I also tried now with the MSI 321URC QDOLED, and same there, only being recognized as an sRGB monitor in SDR mode on wide-gamut.com, regardless if I specifically choose P3 or Adobe RGB profile on the monitor. Even with proper MSI driver /ICM installed in Windows 11.

Which makes me question; Michael, did you really get this to work or not? If so, how?

If not, this seems to me like an OLED issue. To able to utilize wide gamut on an OLED monitor (in real every real world applications) the monitor needs to be in HDR mode. Which is a bummer!

My Asus ProArt PA32UCR IPS monitor is being correctly recognized as a wide gamut P3 on wide-gamut.com.
Even my 10 year old SDR Dell UP2716D is being recognized as a P3 wide gamut monitor.

This is particularly a bummer if HDR mode in any way is limited (like on the LG 32GS95UE/UV/UX).

HDR mode on the LG 32GS95 does not look very good, even after having calibrated it using Microsofts HDR calibration tool.  So running the monitor constatnly in HDR mode, is just not an option.

If my suspicions are correct, this monitor is going back. Still hoping I can be proven wrong.

After some break in, my monitor proved to be more accurate in the factory default Gamer 1 mode.  I downloaded the proper drivers for the monitor from the Korean website and installed those.  Once that was done, I went to https://www.wide-gamut.com/test, and my monitor is passing the tests there.  It seems to be recognizing SDR and wide gamut content and displaying it correctly.  As so HDR, you do have to turn it on in Windows when you want it, and off when you don’t, at least on my monitor.

[Ole_72]

I know I have to turn on HDR in Windows to enable it. My point is; I can not get my sample of the monitor to pass the tests at wide-gamut.com while in SDR mode – only when in HDR mode.

Again, so what you are saying is that your sample of the monitor, is passing the wide-gamut tests at wide-gamut.com, while your monitor is in SDR mode and Gamer 1 profile, and not HDR mode?

If so, could you please provide a link to the driver you are using?

Yes, that is what I’m saying.  The LG Korea website is a bit odd, but go to https://www.lge.co.kr/support/product-manuals, translate to English,  and start typing in your model number – 32gs95 – and select either the WB OR BB version.  It doesn’t matter which.  Once  you do that, scroll down for the list of drivers.  I’ve tried to attach the Windows 11 driver to this message.  I’ve also attached a JPG of the results of my monitor on the wide-gamut test page.

When you change your monitor to wide gamut from the OSD, do the desktop colors become more saturated compared to the previous sRGB mode?

[Ben]

I think it is the windows displaycalibration profile takeing over.    Disable windows color management in Windows 11 display properties advanced color management.   It is under display / advanced display.     Running the windows colorcalibration in SDR will make a  srgb profile useing hardware info from the display.   Windows color management device profile  does something.   It is not documented what does what to me.   WCS is different than ICC.    Could try changeing the WCS device profile.

[Michael]

When switching between the default Gamer 1 mode and sRGB mode, yes, the colors seem to be more saturated.  I don’t have a colorimeter, so I can’t be sure.  I do know I don’t see any unnatural oversaturation, even on skin tones.

[Ole_72]

The driver you provided a link to is the exact one I already downloaded and installed. It will not make my monitor pass the test at wide-gamut.com, while my monitor is in defaults native wide colorspace in Gamer1 (SDR mode) .

Only way for me to get my monitor to pass the test at wide-gamut.com, and hence being properly recognized as a wide gamut monitor, is to enable HDR mode on the monitor.

I have tried both enabling and disabling Windows 11 ACM (auto color management), nothing helps.

This is driving me nuts! 🙁

Any more tips would be appreciated…

[Michael]

The only other thing I can thing of is this…  Make sure you have the color profile that is included with the driver set as the default in Windows Color Management.
