No errors...But display is blank

[Just Me]

I was able to force my external monitors to run on the NVidia card and the laptop to run on the Intel. Unfortunately, I forgot how I did it.

I ran so many troubleshooting steps trying to fix this that I cannot say for sure. You might try installing new USB drivers from the manufacturer's website. I had to follow these steps to update my USB drivers as Intel does not write any for Windows 8:

I also disabled the following Intel services - hkcmd Module, igfxTray Module, and persistence Module. They were set to auto start but are now set to disabled.

You can download DevManView from nirsoft.net and write a batch file to run at startup to automatically enable the Intel graphics card. At least then if you forget to re-enable it before shutdown, you will be able to use your laptop when you are away from your external monitors.

To use DevManView automatically you will have to turn off UAC. There is a way to turn it off for one application only. Microsoft released a KB on how to do it and then withdrew it. This page goes over the details:

I have not tried it. There is also an application that turns off UAC for selected applications called UAC Trust Shortcut. I have not used it either.
