=== OpenGL and Video input/output === | |||
The following answer covers missing video input/output and knocked out OpenGL support after updating nVidia drivers. | The following answer covers missing video input/output and knocked out OpenGL support after updating nVidia drivers. | ||

To do so, I'd suggest the following procedure: | To do so, I'd suggest the following procedure: | ||
# Enter Control Panel > Add/Remove Programs<br /><br /> | |||
# Remove both drivers "NVIDIA Drivers" and "NVIDIA WDM Drivers".<br />If asked to remove stored nView profiles, answer "No"<br /><br />If your current driver was very old or if you have problems to install newer driver versions, perform steps 3) through 5):<br /><br /> | |||
# Reboot into "Safe Mode" (press F8 while booting)<br /><br /> | |||
# Remove C:\WINDOWS\system32\nv4_disp.dll and C:\WINDOWS\system32\drivers\nv4_mini.sys if present and any copies of these files in C:\WINDOWS\system32\dllcache (Note: directory has 'hidden' attribute). I don't think you need a commercial driver cleaner utility to get rid of the driver.<br /><br /> | |||
# Reboot and abort the "Found New Hardware Wizzard" that may pop up.<br /><br /> | |||
# If you need to try out several driver versions, you can speed up the test cycle by setting a "System Restore Point" entitled "No graphics driver" right now.<br /><br /> | |||
# Install the display driver. Do not install the WDM driver yet. System detects "NVIDIA GeForce4 MX 440" and uses newly installed driver. You only need to reboot the system immediately if the setup recommends to do so.<br /><br /> | |||
# Install WDM driver and reboot.<br /><br /> | |||
# "Found New Hardware Wizzards" will pop up and detect devices<br />"nVidia WDM A/V Crossbar" and<br />"nVidia WDM Video Capture (universal)"<br />and offer to search for a suitable driver.<br /><br /> | |||
# Select "No" for search and let the system install driver automatically.<br /><br /> | |||
# System will use the newly installed WDM drivers for both devices.<br />During installation, it may complain about missing certification - confirm to continue setup.<br /><br /> | |||
# If driver exposes any bugs, restore system to point "No graphics driver" and go back to step 7)<br /><br /> | |||
# Send a complain to NVIDIA or ATI if your hardware is in the "Products supported" list but not all features (like video capture) are supported by the newest driver version.<br />The NVIDIA and ATI programmers are still very busy to compete against each other. They apparently do not test new driver versions with all released hardware versions. So they need this kind of feedback in order to track down their bugs or at least publish compatibility issues on their web site. | |||
