How to Install EDID Override INF Monitor Drivers in Windows 8

November 9th, 2012 · 2 Comments · Other S3D Tech

Microsoft has been requiring digital signatures for device drivers for a while already, so if you’ve used EDID override INF monitor drivers already, you probably know about the option to Disable Driver Signature Enforcement in Windows 7. In Windows 8 however Microsoft has removed the F8 key during boot that you could’ve used to easily and quickly disable the Driver Signature Enforcement, the official reason for that is the optimizations made in order to improve the speed and performance of Windows 8. The good news is that the functionality to disable the Driver Signature Enforcement is still there in Windows 8, just the way to call it is a bit different.

If you are using the tile-based shell:

1. Hit the physical Windows button to see the new tile-based menu
2. Move the mouse to the bottom right corner of the screen to call an extra menu
3. Select the Settings option (gear icon) and click on Change PC settings
4. Go to the General menu, scroll down the list of options to Advanced Startup and click on Restart Now
5. You’ll see another menu with options, click on Troubleshoot, then Advanced Options and then Startup Settings
6. You’ll see another Restart button that you need to click on in order to reboot Windows 8 with the extra startup options
7. Hit 7 or F7 when you see the Startup Settings menu in order to load up Windows 8 with Disable Driver Signature Enforcement directive active.

If you are using the old Windows 7 shell or just to make your life easier not having to go through the full procedure described above each time, you can create a simple BAT file with the following contents in it and place it on your Desktop (shutdown.bat for example):

shutdown /o /r /t 0

By running the BAT file you’ll be taken directly to step 5 of the above guide and you need to only follow the rest of the steps in order to get the Driver Signature Enforcement disabled and be able to install an unsigned EDID override INF monitor driver. After that you can just reboot normally and the Driver Signature Enforcement won’t be active anymore and you can continue to feel safe… ;)

Share Your 3D Monitor, 3D HDTV or 3D Projector EDID Data

February 16th, 2012 · 13 Comments · Other S3D Tech

Let us try to make a useful list of the EDID identifiers for different 3D-capable display solutions, so that owners of different stereoscopic 3D devices can experiment by making their display recognized by Windows and other software as a different product and thus behaving differently or getting some extra features available. No matter if you have a passive, active 3D or even autostereoscopic 3D solution please follow the simple guide below and share your EDID identifier data if it is not already shared by somebody else. It is something that you can do in no time and with that you might be able to help many other users…

How to save your Monitor EDID info:
– Get the free Monitor Asset Manager
– Install and Run the Monitor Asset Manager
– Click on the File menu and select “Create INF…
– Name the file with your display model and upload it in the forum.

When posting the INF driver for your 3D display it might also help if you include some additional information, such as what interface the monitor is connected over and if you also have some sort of adapter or maybe a receiver connected between the computer and the display. This might be important especially for HDMI connections where you may also need to have support for audio over the interface and not only the 3D video.

You can post your 3D Monitor EDID INF driver here in the forum…

Make Your Passive 3D Monitor or 3D HDTV Work with 3D Vision

February 11th, 2012 · 173 Comments · GeForce 3D Vision

Not that long ago Nvidia has introduced their “Optimized for Geforce” program that allows some certified passive 3D monitors such as Acer HR274H and Acer GR235HA to work with the 3D Vision video drivers, allowing you to use the full 3D Vision functionality with a passive 3D display. Prior to that in the old stereoscopic 3D drivers Nvidia had support for passive 3D monitors from Zalman, and although the newer Zaman 3D monitors were bundled with the iZ3D driver and not anymore with 3D Vision, they actually do work with 3D Vision and get optimized for the Optimized for GeForce functionality. If you have a passive 3D LCD monitor or even a passive 3D HDTV that is not supported by 3D Vision (Optimized for GeForce) you can actually quite easily make it work by installing a monitor driver with EDID override that will tell Windows and the video drivers that you actually have a different compatible display.

Here is an example using LG’s D2343P passive 3D monitor with installed Zalman ZM-M240W 3D Monitor EDID Override and the LG gets recognized as a Zalman 3D monitor. You need to install the INF driver from the link over the monitor driver you currently have installed from the Windows Device Manager, using the Have Disk option and if when get a warning message just confirm that you want the driver installed anyway. After that you may have to restart Windows in order for things to start working and the Nvidia video drivers to be able to properly recognize and activate the 3D support.

Opening the Nvidia Control Panel and going to the Stereoscopic 3D settings page you should see the “Optimized for GeForce” logo if everything is working properly and clicking the Test Stereoscopic 3D button should bring the Nvidia 3D test on the screen that should be working just fine when you put on the passive 3D glasses that came with the monitor. After that you can the 3D Vision Photo and Video Player and even play games in stereo 3D mode just like you would with an active 3D display and with the 3D Vision glasses. Of course using passive 3D would mean that you would have some limitations like the half vertical resolution when in 3D mode, the lower vertical viewing angle etc., but still you will be able to use passive 3D displays with your Nvidia graphics card and with all the features that 3D Vision offers, an not only with the iZ3D or the DDD TriDef 3D drivers, so you will simply have one more alternative available. I’ve tested this method and it works just fine even with the latest 295.51 beta video drivers from Nvidia, so you should have no trouble making it work. If you try this on your passive 3D setup, feel free to share your feedback and how it works with your specific 3D hardware, thanks to Butmuncher for finding out about this method.

Update: Since the Zalman EDID override does not support audio for HDMI connection to the monitor, you should use this driver only for DVI connection to the passive 3D display. If you wan to use HDMI connection and have audio over the interface as well, then you should install the Acer EDID override driver. Both INF files are included in the archive below, and special thanks to Greg Gilbert for providing the dump from the Acer HR274H display.

Here you can download the EDID override INF files that you would need for this to work…
