I have since learned that the AMD graphics driver installed in the Samsung Series 7 Chronos #NP780z5E-s01ub is a pre released factory installed driver with no additional updates. Version 22.214.171.124. is all there is available until the AMD, I guess, releases the product and then Samsung will define what updates we will need. It is listed in devices as an 8700 Series AMD.
The reason the auto detect here at the AMD site cannot detect our AMD graphics driver is because it's not a released version they are supporting yet.
The fact that you uninstalled the windows 8 that came with the computer for another version ould very well be incompatable with the only AMD driver version Samsung is offering for that computer. There are no patches, or updates for this driver at all. Pre-release, as I am told, is, AS IS! Samsung informed me this morning any new updates for that driver will come when it's appropriate to release them.
