Is everything plugged in? You may need to tell Windows to enable the TV.
Right click desktop -> properties -> settings tab -> make sure 2 monitors are showing up and both are enabled.
Make sure you clear all the old drivers off your system before installing new ones.Fucking great. Now my Windows is telling me I need to reactivate because of significant hardware changes, and that my CDKey has been used too many times.
Also, the Nvidia drivers I just downloaded off of the Nvidia website won't install.
This has just gotten real shitty, real fast.
