I have a VAIO SVZ1311C5E notebook with a docking station VGP-PRZ20C. The docking station is equipped with a grafic card AMD Radeon HD 7670M while the notebook is equipped with an Intel HD4000 grafic card.
After having installed Windows8 I am not able to activate the grafic card of the docking station any more. Obviously I have not yet found the correct drivers. Unfortunately the are no drivers to download especially for the docking station from the Sony websites.
The grafic card displayed in Windows control center is "AMD Radeon HD 6700M Series (Microsoft Corporation - WDDM v1.20)". This obviously is not correct.
According to the technical specification of the docking station the grafic card should be a "AMD Radeon HD 7670M" (when SVZ131XX is connected).
I already tried the following:
1) Downloaded "catalyst_mobility_64-bit_util.exe" from AMD's website. Unfortunately the software states that grafic adapter is not supported due to inkompatible hard/software".
Some of the features may not work after the upgrade to Windows 8. Drivers and steps are available to troubleshoot the issue. For U.S model computers, Power Media Dock will not work as with Windows 8. A software update is tentative for Windows 8 by mid January.
