Here are a few things you might want to try:

1. **Update Firmware**: Check if there's a firmware update available for your monitor model (LC32G54TQWIXCI). Sometimes, firmware updates can fix compatibility issues[43dcd9a7-70db-4a1f-b0ae-981daa162054](https://community.intel.com/t5/Graphics/Intel-UHD-Graphics-630-I-suspect-causes-my-screen-to-randoml... "1")[43dcd9a7-70db-4a1f-b0ae-981daa162054](https://community.intel.com/t5/Graphics/UHD630-4K-screen-flicker-with-HDMI-only-during-XTU-stress-te... "2").

2. **Check HDMI Cable**: Ensure your HDMI cable is high-speed and supports 4K resolution. Sometimes, a lower-quality cable can cause flickering issues[43dcd9a7-70db-4a1f-b0ae-981daa162054](https://community.intel.com/t5/Graphics/UHD630-4K-screen-flicker-with-HDMI-only-during-XTU-stress-te... "2").

3. **Disable Hardware Acceleration**: On your PC, try disabling hardware acceleration in your browser and other applications. This can sometimes resolve flickering issues[43dcd9a7-70db-4a1f-b0ae-981daa162054](https://community.intel.com/t5/Graphics/Intel-UHD-Graphics-630-I-suspect-causes-my-screen-to-randoml... "1").

4. **Change Refresh Rate**: Try changing the refresh rate of your monitor to see if a different rate reduces or eliminates the flickering[43dcd9a7-70db-4a1f-b0ae-981daa162054](https://community.intel.com/t5/Graphics/UHD630-4K-screen-flicker-with-HDMI-only-during-XTU-stress-te... "2").

5. **Check for Driver Conflicts**: Ensure there are no driver conflicts between your Intel UHD Graphics 630 and the NVIDIA GeForce 650 TI Boost[43dcd9a7-70db-4a1f-b0ae-981daa162054](https://community.intel.com/t5/Graphics/Intel-UHD-Graphics-630-I-suspect-causes-my-screen-to-randoml... "1")[43dcd9a7-70db-4a1f-b0ae-981daa162054](https://community.intel.com/t5/Graphics/UHD630-4K-screen-flicker-with-HDMI-only-during-XTU-stress-te... "2"). You might need to update or reinstall drivers for both GPUs.

6. **Try Different Ports**: If possible, try connecting your monitor to a different port on your PC or using a different cable (e.g., DisplayPort if available).

7. **Monitor Settings**: Check your monitor's settings to see if there are any specific options for reducing flicker or adjusting the display.

8. **Contact Support**: If none of these solutions work, it might be worth reaching out to the monitor manufacturer's support team for further assistance
