How can I adjust screen brightness in Windows 10 using bootcamp for my 24" LG Ultrafine 4K display?

I clicked on the Windows icon in the left bottom corner.

Then, clicked on Apple Software Update.

I did the update which restarted my computer.

Now, when I go to Boot Camp Control Panel after clicking on Boot Camp, I see a tab for display.

From there, I can slide the slider with my mouse to control the brightness on my LG Ultrafine 4K display!

Thank goodness! I am very relieved.

This is solved.

No the keyboard keys do not work. And I believe the bootcamp drivers are installed, but the boot camp control panel only gives me options to adjust the keyboard and the trackpad. No tab for external monitor

Yes, the keyboard keys change the slider, but the only screen that dims and brightens is the 15" MacBook Pro screen, not the LG Ultrafine 4K external monitor
