Ok, so this is actually unrelated to what I was planning on posting, which was GPU brute-force password cracking and some stats I pulled using Multiforcer and different nVidia cards I had laying around. In order to get Multiforcer to run I needed to update my nVidia driver to the latest version, which is 266.58. The problem is I have a Westinghouse LM2410 monitor that has the good old EDID issue with the nVidia drivers. No problem, easy fix right? Modify the inf file with the correct values for my monitor in the OverrideEDIDFlags0 and we are back in business. Problem is that, with the new driver anyway, adding the binary value for the EDID override via the inf file on Windows 7 64-bit doesn’t seem to actually add the value to the required key. But, as this approach was simply adding a binary value to the registry during install, and it is just as easy to add it manually post driver install. If you’re not familiar here are some simple steps to manually add the value:
1. Run regedit, find the Video key under HKLM/System/CurrentControlSet/Control/Video
2. Inside you should see a bunch of GUIDs, open each one until you find the one with two folders, 0000 and 0001, that also have subkeys of Display, Settings, and VolatileSettings.
3. Create a .reg file to add this key, or do it manually. The binary value you need to add under the 0000 key is going to be specific to your monitor, so if you don’t have a LM2410 then do not use these settings. Here is what I added (right click in in the pane showing the contents of the 0000 key, choose new -> binary value):
Value name: OverrideEdidFlags0 (that’s a zero)
Value: 5c,85,80,51,00,ff,ff,04,00,00,00,7e,01,00
4. Reboot and your LM2410 should now be recognized as a monitor, not a HDTV, and should look good as new.
If you don’t have the LM2410 monitor then this probably isn’t going to help you. I know other people have posted this issue and solutions for Acer and Viewsonic monitors on other sites…good luck. Now I can brute-force those damn NTLM hashes and not strain my eyes doing so. Hope this works for you.
