If your refresh rate settings are grayed out, it could be due to a few possible reasons. Here are some steps you can try to resolve this:
1. **Update Display Drivers**: Sometimes outdated or incompatible drivers can restrict display settings. Check if you have the latest graphics driver installed by visiting your GPU manufacturer's website (e.g., NVIDIA, AMD, Intel) or through Device Manager.
2. **Check Display Cable and Port**: Ensure that your monitor is connected using a cable that supports the desired refresh rate (such as HDMI 2.0 or DisplayPort). Some ports or cables may limit your refresh rate options.
3. **Monitor Settings**: If your monitor has built-in settings, try adjusting the refresh rate there. Some monitors allow changing settings directly through an on-screen display menu.
4. **Resolution Settings**: Check if the current screen resolution supports your desired refresh rate. Some resolutions may limit the available refresh rate options.
5. **Try a Different Port**: If you're using a desktop, try connecting to a different port on your GPU, as some ports may have different refresh rate capabilities.
If none of these solutions work, check your monitor's documentation to confirm that it supports higher refresh rates at the current resolution, or reach out to the manufacturer for further assistance. This problem was happening with me too while playing rummy wealth 999 but I solved it by this method.
