Lenovo yoga 520 brightness issue

I have just bought my laptop 2 days ago. It has been updated to windows 10 and now I can't increase or decrease the brightness using the button or in settings as there is no option for this. I have tried what lenovo has suggested with the moniter, however my moniter is a generic non PnP moniter. I am just wondering how to fix this issue. Any help welcome please.

Re: Lenovo yoga 520 brightness issue

To be clear, you're using the laptop with an external monitor?

If you lost brightness controls after a Windows Update, you might need to roll back to a prior version and let it take the update again. Which version are you on? Both 1803 and 1809 have caused the issue for some users.
