If you are okay with the quality of the graphics then fine. But it wont even let you play solitaire!

Standard VGA
Well, I don't have blu-ray but my TV episodes (AVI files) still played okay with the standard VGA graphics. You can't get all the usual resolutions though. You can't get Hardware Acceleration to run, so games are no good - even solitaire! I definitely would never settle for cut down graphics - what a waste! Sony could so easily rectify all this!

Mass Storage controller- Nvidia 8400M-GT, and Touchpad
Hello all -
Just did a clean install of Windows 7 premium on my Sony VGN-FZ21E.
Suffered the following problems afterward - but managed to fix all but one of them... Perhaps I've just been lucky, but might work for others.
1/. Wouldn't recognise the Nvidia 8400M-GT - showed up as a generic VGA adapter in device manager...
2/. Partial loss of of touchpad function -no scroll faility etc - showed up as a generic PS2 mouse in device manager...
3/. No drivers at all installed for the Mass Storage Controller - (card reader..)
4/. Device managetr showed the display screen as being a generic PnP monitor.
I had backed up the machine before the clean install, and I'd also created some discs using the Windows Transfer wizard - none of these however would fix the above problems. My recovery discs also proved useless.
Went to Sony website - logged in my machine serial number and went to the download section. Clicked on the originally installed tab and dowloaded the original drivers package direct into the temp folder on the C drive (all 113 Mb of it...)
Went into device manager and told it to search for new drivers on the C Drive - three minutes later the 8400M the mass sotrage controller and the touchpad were all up and running.
After that, visited the Nvidia website and downloaded the full application pack for the 8400M GT and now all singing and dancing ...
The only minor niggle I still have is that device manager still shows the display as being a generic PnP display. Not really a problem though as doesn't seem to have affected image quality now that the 8400 is fully functioning.Last edited by Koru; 13 Nov 2009 at 23:30.

I also have got everything right on my Sony Vaio, except for device manager showing generic pnp monitor. Has anyone got a fix for this? Does it matter or make any difference for games or such? Anyone know? Thanks.

This worked!!!

I have a Sony Vaio VGC LT19U on which I did a clean install of W7 64 bit, but had the nVidia driver problem with the nVidia GeForce 8400M GT. I have looked high and low. Tried several modified nVidia drivers from laptops2go.com. Tried modifying inf files myself, used the nVidia Mobiiity Modder Tool. All allowed the display to work properly but I COULD NOT PLAY BLU-RAY disks! This worked! The Cyberlink PowerDVD still has a red mark next to the newly installed driver but it works so I don't care. I am having some issues burning DVDs in some video creation software (Ulead VideoStudio X2) but not sure yet whether that is problem with driver or the poorly documented and explained software package...
