If the suggestions you have been given don't work, you may have a defective monitor profile.

Go to Control panel > Color management, and try setting the monitor profile to sRGB (use Adobe RGB if you have a wide gamut monitor).

You will need to restart Lighroom after changing the profile.

If this fixes the issue, you should ideally calibrate the monitor with a hardware calibrator, which will also create a custom monitor profile that accurately describes your monitor.
