Workaround for SVZ and Z2 PMD with Windows 8

I wrote this thread to confirm that a third party driver for AMD+Intel works for PMD in Windows 8.
This is not what I found, I just follow some steps from other thread here, I forgot where it is.

You need Leshcat driver pack dated Jul 12. Run it to extract driver to a location.
Then go to device management to update to extracted drivers.

My SVZ is now working on both stock lcd and external display. Brightness works fine.

Thank you! What about undocking or switching between intel and AMD part?

I just uninstall AMD 6650M driver and clean all files.
I downloaded and installed new package from Leshcat dated Nov 2 2012 12.10

It worked perfect. Undocking button worked. I disconnect and reconnect dock and it also worked perfect.
To use Intel, dock has to be disconnected. If dock connected, AMD will be used. Correct me if I am wrong.

Because of PMD driver issue for Windows 8, I am wondering if Sony is temporary taking it out to work on this issue for a new fresh model.

 

Hm, so i think it is possible to use the Z series with same PMD features as on running windows 7? Maybe it´s time for an upgrade

 

I can confirm it working but for me lashcat driver installing available only in test mode. As a result - a watermark on right desktop corner (((( How you installed the driver ( from .exe file ore device manager)?

 

Leshcat installer has an option for you to turn off watermark.
However, I found out version 12.10 dated Nov 2 worked without need of turn on TESTSIGNING.
I turn it off on my and and driver still worked.

 

Meaning of "TEST MODE" is to turn off checking of Digital Signing for driver. Third-party drivers may not have digital signing, so Windows 8 won't let it run.
Basically, Windows works the same under test mode or not except it will accept digital unsigned drivers to work.

 

One question to you guys.
I have my external monitor connected to the PMD via HDMI.
Now when the notebook screen is turned off (only the external monitor is active) and I restart windows, still only the external monitor screen will be used but the backlight of the notebook screen turns on.
To disable that I have to press win+p, change to "PC screen only", press win+p again and choose "second screen only".
Now the backlight is turned off again - until the next windows reboot.

Unfortunately this even affects standby and hibernate - do you guys have this issue as well? I'm using the beta6 from Nov 2012 leshcat driver.
