I know there are a lot of discussions about this already. But im hella mad right now.
I installed Windows 10 four months ago and noticed fast that i cant play anygame stretched with a 4:3 Resolution.
I looked up many Support threads and couldn't find any answer how to solve it, I only found a Statement which says that ist a problem with Windows 10.
But in my opinion ist not a problem with Windows 10, ist a problem with the amd Driver cause every issue is fixed if you run your Windows 10 with an amd Driver for Windows 8.1.
But thats not a solution forever because it brings too many issues with it.
However i tried every single driver for Windows 10 with 0 success.
For people with the same issue: Install a Windows 8.1 driver (Version 14...)
If someone knows a fix for the newer drivers please let me know.
PS: I wish all of you good luck solving this issue. You will Need it because its seems like AMD does not give a **** about this.
