Radeon HD 4850 not working properly after update to newest drivers


I have windows 10 64 bit and Radeon HD 4850 card. I found out that my system recently updated drivers into version 15.200.1062.1003 from 28.07.2015 via Windows Update.

Sorry for polish on the screens, but I hope that doesn't have too much impact.


Couple of thing happened then:

  1. System was recognizing only one connected display, ignoring the second one
  2. It allowed only couple of resolution options to choose from: 800x600, 1024x768, 1152x864, 1280x1024:pastedImage_5.png
  3. When I have chosen to show advanced settings of the card, it said it's using "Microsoft Basic Display Driver":

I therefore manually reverted the driver to previous one: 8.970.100.9001 from 13.01.2015, which is working properly: it recognizes two connected displays, and allows to choose proper resolutions: 1920x1080 and 1280x1024.


However with this driver some of videos (mostly through Silverlight VOD components) don't play correctly - I can see only green screen. I was curious and checked and it looks like new driver solves that issue for me. However due to the other factors I had to revert anyway.

I would appreciate any guidance how to solve the issue.

Here are my specs, FYI:

  • AMD Phenom II X4 970
  • Asus M4A88T-M
  • Gigabyte ATI Radeon HD 4850, 512 MB
