I'm not sure if you have the same type of problem I had, but perhaps something in this will help.
I had display issues when I updated my old desktop PC from Windows 7 to Windows 10. (This PC is more than 5 years old, but it still runs well. The monitor is an HP 25" screen.) The screen display was all "mooshed together" when I booted up into Windows 10. I think this was because the Catalyst Control center for my ATI Radeon HD 4300/4500 video card was out of date. The installed Catalyst Control Center was dated 4/19/2010 and was version 3.0.765.0 (and yes, you're right, that's an ancient driver. I just don't bother updating drivers unless I am having problems).
I searched on the Internet for a solution. (And I saved a text file with all my steps in case I ever needed to follow the breadcrumbs and redo this.) This link was helpful:

This AMD support site had the Catalyst Legacy 13.1 and 13.4 drivers:
http://support.amd.com/en-us/download/desktop/legacy?product=legacy2&os=Windows 8 - 64
I downloaded versions 13.1 and 13.4 of Catalyst Control Center.
Contrary to the advice, I then installed version 13.4 (by double-clicking the downloaded executable file) without deleting the old version of the Catalyst Control Center. (Perhaps that was a mistake?) There was no improvement.
I then ran Windows compatibility mode. (Link:
http://www.laptopmag.com/articles/set-compatibility-mode-windows-10) I selected Catalyst Control Center from the list of applications. I let Windows try the recommended settings for Windows 7. Nothing seemed to happen to improve the display, so I told Windows that this hadn't fixed m problem and it offered to run Catalyst Control Center under Windows 8. Again, there was no improvement. At this point, I ran Windows Screen Resolution and changed from 1920 x 1080 to a lower resolution and OK'd that. I then changed back to 1920 x 1080 and the problem was fixed. (I'll be darned if I understand why.) So I saved that setting. Everything has been fine since.
I am unsure now if it was absolutely necessary to run the Catalyst Control center under Windows 8 compatibility. I don't know what would have happened if I had installed version 13.4 of Catalyst Control Center, ran screen resolution, changed to a lower resolution and OK'd that, and then changed back to 1920 x 1080. And I don't know what might have happened if I had exactly followed the original advice in that hyperlink. But in any event, the problem was fixed !!
