LaptopVideo2Go--Which Driver?

I recently bought a Vaio SZ780.The Nvidia card is GeForce 8400M GS.

From a link somewhere on this board, I found the web site laptopvideo2go, which enables one to use more recent Nvidia drivers, than are on the Sony site.

In reading the site, it appeared that one could use any of the NVidia drivers there with any Nvidia card, as long as one replaced the .inf file in the package with the corresponding modded .inf from the web site.

So, I downloaded the newest driver from the site, 179.13 I believe, and the corresponding modded .inf. I unpacked the .exe package, and replaced the original nvar.inf file in it, with the modded one.

I uninstalled the current Nvidia drivers (newest from Sony site), and rebooted. It loaded Windows standard VGA driver.

I then tried to install the new package via the setup.exe file within it. It appeared to be installing correctly. I re-booted. Didn't work. No Nvidia drivers loaded.

Uninstalled the package. Rebooted again. This time tried to install via Device Manager, Update Driver, chose that modded inf in the new package. Got a response that the current generic VGA driver was a better choice, and did not install the Nvidia driver.

Tried to install by right-clicking the modded inf file, choose Install. Got a message that that inf file does not support that mode of installation.

For the moment, going back to the driver package from the Sony support site.

Has anyone got the newer Nvidia drivers from laptopvideo2go to work on your Vaio? With which driver? Why don't they all work, as it appears to say on the main page of that site?

If you did succeed in installing a newer driver, did you find any improvements with it, over the one on the Sony support site. What exactly was improved?

Or--better just to stick with the Sony driver?

 

Hi.

You need to use the update driver method and have disk in device manger as you have to force the system to take the driver, you cannot use the setup with an modded info file.

I will borrow this topic, since I have a similar question.

I have SZ61XN with 8400M GS gfx. According to nvidia webpage, this gfx should support Hardware Acceleration in HIGH-def movies - h264, VC1 and mpeg4.

So I upgraded my gfx driver to the latest one from the laptopvideo2go and installed it corretly.

But HA is not working in any software, I am using PowerDVD and Arcsoft TotalMedia, but it does not work.

I have a HTPC with 8500 gfx, so I know how to set up things and that it should work, but it seems drivers are messed up or there is some reason I dont know about.

Anybody here that is able to use HA with high-def movies?

 

Here are the directions on how to do it, from the guide you cite above:
(my comments below it)
---------

1. Click on the driver version (ex: 91.33) to download the drivers.

2. Once finished, double-click the .exe file and extract all drivers (default location is your desktop). A folder will appear with the name of the version of the driver (ex: 91 33). The installation process will not start yet (you don't want it to anyway).

3. Still on the LaptopVideo2Go website, right click the .INF and hit "Save Link As...". Put it somewhere.

4. Now, take that .INF file, and drag it into the extracted drivers folder. Overwrite when prompted.

5. Now you will be able to install the drivers (you needed to replace the .INF file to do that).

6. Open the extracted drivers folder.

7. Double-click Setup.exe, follow the instructions.

--------------------------

I followed those directions exactly. As I wrote, it appeared to install correctly, but didn't. After reboot, I got the generic Windows VGA driver. Tried a few times.
