How to roll back ATI Radeon HD 4600 Series driver

client came in this morning after being away for the holiday.
he turned on his Windows 10 Pro pc with 2 monitors and only one monitor was recognized.
He rebooted, Disconnected both displays, plugged each display into the adapter and each worked.
When he goes into 'display' settings, it only shows one display.
Clicking 'detect' returns nothing
Device manager only shows one display, even though two are connected.
Device manager does have a problem with the video adapter,
ATI Radeon HD 4600 series, shows no drivers installed
The driver tab shows:
7/25/17
22.19.128.0
The rollback driver button is greyed out and the computer is not configured for restore points
I tried to find new updated driver, but it comes back that the latest is already installed.
How do I rollback or find a driver that will allow both displays to work?

With this being such an old graphics card, it's likely using the generic Microsoft driver that windows will install automatically. To combat this you'll want to navigate to Device Manager and uninstall the current display driver. Do this with driver updates disabled:

Next, you'll want to download this driver:

http://support.amd.com/en-us/download/desktop/legacy?product=legacy3&os=Windows%2010%20-%2064

Restart the machine. You should then be able to reverse the changes you made in step one as the AMD driver is registered for Windows 10 and SHOULD (mind you should) be seen as the most up to date.

And  check this current thread where you can sympathise with another customer in the same situation.
A workaround from the AMD forums is included

If Roll Back driver is greyed out, that means there is none. I see that myself in my own Device Manager. I have both:  Can be rolled back and Cannot be rolled back.

So you need to ask ATI support for an older driver (which may not work or may just update again).
Acronis True Image 2019 just released!

Create a reliable backup. Make sure you always have dependable copies of your data so you can restore your entire system or individual files.

Aha, then I am not the only one with this problem.
However there is one trick. In device manager click on you video card and select update the driver. In opened window select let me select Browse my computer... then in next windows select “Let me puck from a list of available drivers...” and there select the older driver.

Hello,

I experienced the same problem after a Windows update from last week. Since today I didn't find the answer but I just discovered I now can select an earlier installed driver. This option was not there 2 days ago so maybe Windows updated this in the past few days.

Device manager >> video card >> update driver >> choose option: install older driver. Problem solved.

To think I almost bought a new video card for my old desktop :)

Let me correct my instructions.
In Device Manager you need to click on video card - update driver - a window will open with double choice - select Browse My Computer - then select “let me pick up from a list of available drivers”. You will see older driver there.
I had this problem all of sudden after some updates last week. Fixed through the same steps.

Turns out after the windows update, the driver was changed. And you are correct, Windows 10 did not support the video card with two monitors. We replaced the card and all is good. Thank you all for your input.
