    Leshcat drivers worked like a charm on windows 8.

    It jumped from 5.9 (intel) to 6.9 (amd).

    Thanks for the heads up. Works perfectly. Don't know if i need to install any other driver. Although I think i did with the intel ones.

    @ Highlander, Redsand:

    Anyone care to post their notebook model #, graphics card name or PID/VID, o/s build #, and driver versions installed, along with any additional instructions?

    Also, can you confirm whether you have Switchable Graphics capability (i.e. switch between Intel HD ONLY and Intel HD + Radeon HD), Intel WiDi, and/or any negative effects on battery life?

    I have switchable graphics
    I had to remove the drivers completely in order for leshcatlab drivers to work. I followed everything from the leshcatlab website and has worked flawlessly.

    Let me start by saying, thanks to Alphastar for posting the following information. I was able to use the following information you posted earlier to correct the problem I was having with getting my HP-dv6t-6100 CTO model laptop's Intel Wireless Display feature to work again, after having upgraded it to Windows 8 from Windows 7 Ultimate. However, I still seem to be having a re-occurring issue with my AMD Catalyst Control Center functioning properly. I still keep getting an error message regarding not being compatible with my current graphics driver at each system startup. Using the resource information Alphastar posted here, I took the following steps to address the graphics issue and restore the functionality of my system's wireless display feature:

    1. I uninstalled both of my current graphics drivers (Radeon and Intel).
    2. I downloaded the replacement drivers list here by Alphastar:

    AMD: +graphics&ProductProduct=2nd+ Generation+Intel%C2%AE+Core%E2%84%A2+Processors+with+Intel%C2%AE+HD+Graphics +3000%2f2000
    3. Rebooted.
    4. Entered Bois Setup upon reboot.
    3. Disabled Dynamic graphics setting in bois setup /set graphics setting to fixed / rebooted normally.
    4. Installed both of the new AMD and Intel replacement Windows 8 Drivers.
    5. While these steps did not appear to fix the problem with the CCC error message continuing to appear at each Windows startup, it did seem to fix the issue with my wireless display not working. I was under the impression that in need to have the switchable graphics feature enabled in the system bios in order for Intel WiDi to work. However That does not appear to be the case with the new drivers installed.

    note: The picture quality is not all that great without both graphics working in tandem, but at least they work now! I think I can live with quality issue for a while until the new official Windows 8 drivers are released for my particular system. That is not to say that my graphics are not working, because they are working just fine. I have no issues with either driver listed under the display section of my device manager with either driver, unlike before installing the new drivers. However, I do still get the error message concerning the AMD Catalyst Control Center not functioning properly, but its related driver does appear to be working.

    Thanks again,
    M. Keys

    UPDATE for Windows 8 RTM (Build 9200):
    Although there are updated AMD drivers as of 15-Aug-2012, the current AMD Catalyst Software Suite 12.8 does NOT support Switchable Graphics:
    See the 4th table at
    As of right now, Intel's HD Graphics 3000/2000 and 4000/2500 driver version is (, dated 11-Jul-2012: Generation+Intel%C2%AE+Core%E2%84%A2+Processors+with+Intel%C2%AE+HD+Graphics+3000%2f2000
    For HP owners (Intel HD Graphics + AMD Radeon HD), there are no available Windows 8 downloads (yet).

    Win 8 AMD Switchable Graphics FAQ: (by Intel/AMD 3000 + 6770M owner)

    Firstly, what is Intel HD Graphics + AMD Radeon HD Switchable Graphics?
    Essentially, this is a notebook with an Intel CPU with built-in HD Graphics technology, as well as an additional AMD HD Radeon GPU.
    This is different from the AMD Hybrid graphics (AMD APU or CPU + GPU) and AMD Dual Graphics (2 x AMD Radeon HD) and AMD Desktop solutions.

    •AMD APU (Fusion) – AMD Accelerated Processing Units
    •AMD Hybrid Graphics (PowerXpress) -
    •AMD Radeon Dual Graphics -
    •AMD Desktop Graphics -
    •Intel HD Graphics - www

    How does it work?
    It uses a custom driver from the notebook manufacturer or a custom-built driver by other 3rd party for the Intel GPU, which is installed via the AMD Catalyst Installation Manager (CIM). AMD switchable features are managed via the AMD Catalyst Control Center (CCC) and packaged together with the AMD Display Driver, HDMI Audio driver, etc. Both drivers (Intel and AMD) carry AMD version numbering.

    •AMD Developer Central: CCC Driver Details -
    •AMD Driver Downloads -

    What does it look like?
    See HP’s Support documentation below.

    •Overview of switchable graphics or dual GPUs -
    •Switchable graphics on notebooks configured with Intel and ATI GPUs -

    Can I get this to work on Windows Vista or Windows 7?
    Yes, absolutely. The notebook manufacturers’ (OEM) drivers should work fine. Also, there are (unofficial) custom 3rd party options that enable additional features and API support. There are also reports of improved performance (for some) with these unofficial drivers, however none claim compatibility with (or support for) Windows 8.

    •Intel’s list of OEMs - Computer Manufacturer Support Web Sites

    Can I get this working with Windows 8 [*] Preview (* = Developer, Consumer, Release)?
    No. There have been unconfirmed reports of success using the following alternatives:

    1.Installing Windows 7 drivers using Windows 8 Compatibility Mode.
    2.Using a custom-signed (via WinDDK) CAT, modified INF driver to support specific PCI vendor and hardware IDs.
    3.Installing Intel and/or AMD Windows 8 Beta/Preview drivers.
    4.Suspending and resuming after installing new drivers to enable PnP detection to fix
    “black” screen and/or Code 10/Code 43 issues.
    5.Installing 3rd party drivers.
    6.Any or all the above methods combined.

    The only confirmed (and supported) working method is to switch the graphics adapter in the BIOS from Dynamic Mode to Fixed Mode (see “What does it look like?” above for HPs). This means that one graphics card will be disabled; this will likely also require the latest system BIOS from the specific notebook manufacturer in order to support this feature.
    If using this method, the Windows 8 Preview drivers from Intel or AMD will also need to be installed to support whichever is the active graphics adapter.

    Why will these alternatives not work?
    Presumably (best guess) because Windows 8 AMD Switchable Graphics is not yet supported by Intel/AMD/OEM notebook manufacturers. Few (if any) OEMs have drivers or support for Windows 8 [*] Preview for their notebooks.
    Note that on Windows 7, the Intel HD Graphics driver is bundled with the AMD CIM/CCC package above, signed by AMD for x64 (i.e. Device Manager says “Intel HD Graphics 3000”, Manufacturer: Advanced Micro Devices, Inc., Version: 8.882.2.3000) and uses custom AMD CCC components (MOMProxy*?) to install/integrate the two drivers.
    Current drivers for Windows 8 [*] Preview (6/2012, **NO AMD SWITCHABLE SUPPORT**):

    •AMD Win8 RP -
    •Intel Win8 RP -

    •Intel’s switchable graphics (official) support position: Graphics — Switchable Graphics feature FAQ
    •AMD’s current 12.4 driver Release Notes state that they do not support Switchable Graphics -

    What else does not work on Windows 8 [*] Preview, and why?
    Intel Wireless Display (WiDi).
    On AMD switchable systems, it seems that Intel WiDi uses the AMD card (secondary display) as the Wireless Display. I have had some success using newer/custom signed Intel drivers on Windows 8 together with the Intel Wireless driver 14.x/15.x and WiDi software version 3.x (i.e. audio worked, but black video on WiDi settop box output to TV).

    [/! \] Unofficial Drivers (WARNING: use with caution - community support ONLY!)

    • are now Windows 8-compatible (Catalyst 12.8 WHQL UnifL for ATi+Intel Graphics, a.k.a. 12.8 WHQL UnifL Release v 5.1 - see posts below)
    • asder00 (AMD Catalyst 12.x 9.001 September 4)

    Confirming that Leshcatlabs' UnifL (Unofficial) driver is working for Switchable Graphics on Windows 8 HPs with Intel HD Graphics 3000 and AMD Radeon HD 6770 (and others too).

    No sign of AMD or HP Official drivers up to now.

    See the first post for details.
