Windows 10: How can I re-enable my Display Adapter that I accidentally disabled?

Hello

How can I re-enable my Display Adapter that I accidentally disabled?

Background
I have a Samsung Series 7 Ultra Notebook 128GB SSD 13.3" (model: NP740U3E-S04UK)
13.3" Series 7 Ultra Notebook 128GB SSD NP740U3E | Samsung Support UK
It comes with a AMD Radeon HD 8570M graphics card, plus a built-in Intel HD Graphics 4000.
For some reason my Brightness control suddenly seems to have gone nuts. I stopped being able to control it when the power is plugged in, and when the power is not plugged in the brightness keeps changing for no reason.

So I tried to install an AMD driver thing (AMD Adrenalin 2020) that I found on www.amd.com but it locked computer completely and after all manner of trouble I finally managed to do a System Restore to get rid of the Adrenalin thing.

Then like a fool, I thought I could reinstall the old AMD driver using Device Manager, so I tried to disable the thing using Device Manager. And now even after a reboot I still can't see the AMD Radeon HD 8570 graphics card. I have tried ticking View ==> Show hidden devices... but that didn't help either!

What should I do?

PS I am using Window10 version 2004 (OS Build 190411.388)

Sorry, was eating dinner.

Yes, the performance tab of Task Manager, at the bottom, is correct way. It looks like your Radeon is primary. Keep in mind that they both will run because they are both enabled, but the system is smart enough to use the Radeon over the iGPU. Example from mine.
