2nd monitor colours oversaturated in LR Classic

I've used LR classic with a 2nd monitor (LG Flatron W2042S) connected to my laptop with a HDMI to VGA adapter for a few years now with no issues. However, since the latest LR update (v13.0.2) the colours keep going out of whack on my 2nd display (very oversaturated, especially reds and greens). Crucially, this doesn't happen to all images on the 2nd monitor window- e.g in survey mode only the selected image becomes oversaturated with the others all still correctly calibrated and consistent with the laptop screen. In loupe mode it sometimes starts OK but then goes oversaturated after a few seconds. Both monitors are calibrated with Spyder 5 express. I'm thinking this may be an issue with which preview is being used by LR? Also in loupe mode, when I try to zoom in on the 2nd monitor, it just goes black, or only a small portion of the photo displays with the rest of the screen black.  Any ideas how to stop this? I've updated the graphics card driver (Nvidia GeForce GTX1050) to the latest version, 546.01

    and if i drag the main LR window (the one with all the tabs and sliders) to the external monitor and use the laptop screen as my second display, the colours also show correctly (even in develop module) on both monitors... This will be my workaround for now.

    Does it make any difference if you disable the GPU?

    Perferences > Performance > Set Use graphics processor to Off.

    No, it's still the same with GPU disabled. Thanks anyway!

    One other fact that may be pertinent: besides the colour issue, I can zoom in on loupe view on the 2nd monitor in the library module, but in the develop module, the screen just goes black at anything above 100% zoom (it's ok below 100%).

     I have tried checking and unchecking the 'use smart previews for editing' option in Preferences/Performance (and deleting the previews.lrdata file and  purging the camera raw cache) but this doesn't make any difference...

    I've also found this only happens when I am in the Develop module: in Library,  the colours are correctly calibrated on both monitors...

    When you calibrate with your Spyder, it creates and installs a new monitor profile.

    Older Spyders have a somewhat bad reputation (it seems that the Spyder Express 5 was introduced in 2017), and it may create profiles that don't work properly with Lightroom (or with the GPU, that handles the conversion from the document profile to the monitor profile).

    The options in the calibration software for the Spyder 5 might be limited, but if possible, set it to create a version 2 (not version 4), and Matrix or Gamma (not LUT) tone curve.

     

    To check for a defective or incompatible monitor profile, try setting it to sRGB.

    The LG Flatron W2042S seems to be standard gamut, so use sRGB for that, but if your laptop has a wide gamut screen, use Adobe RGB for that.

    You need to restart Lightroom (and any other color managed software) for the change to take effect.

    If this fixes the issue, recalibrate with the options I mentioned above. If that's not possible, I recommend getting a new calibrator.

     

    To change the monitor profile:

    Press the Windows key + R, type colorcpl in the box and press Enter.

    Add the sRGB (or Adobe RGB) profile, then set it as default.

      Thanks, Per, I can give that a try tomorrow.  However, the fact that several images on the 2nd monitor are displayed at once with only ONE of them having odd colours (and that the problem only arose this week after the LRC update) suggests this is an issue with LR classic rather than a hardware or profile issue, doesn't it?

      Might be something set wrong in the NVIDIA controlls.

      Specificallt to second monitor.
