I have not tried that yet. I assumed that the onboard would not work with the RX470 active. I will try that today and let you know the result. Thank you!
The new drivers did not fix all. That's the point of my post. I had 3 running monitors, now only 2 work after the Adrenalin update. My AOC monitor went Blue.
Runescape required me to update my graphics driver for my RX470. My 3rd screen went blue. Can't get it to work again. RIIIPPP! (sound of me tearing the RX POS out of my motherboard.)
I am now using the onboard 1G graphics card. Spent $300 on a 4G card just to have a driver update make it...
