I've got a lot here, but here is summed up. I installed a 120hz screen into my laptop. It's working great in every aspect except that I cannot adjust the refresh rate back to 60hz in NVIDIA control panel because the display tab is missing, in fact all but the 3D settings are missing completely. Don't give me the "Perform a clean installation and use DDU" I tried that several times and even reset my computer and none of it worked. Only 3D settings appear in the NVIDIA control panel. I can adjust the refresh rate color settings and resolution for an external display, but not the main one. The 'display' and 'video' settings appear when I plug in an external display but only let me adjust settings for the external display. My question is how do I get NVIDIA control panel to recognize my laptop display so I can change it to 60hz to prevent screen tearing in games like Terraria. I've also tried everything with that game too, and you need to physically set the refresh rate to 60hz to get rid of tearing.
Sorry for the mouthful. Any help would be appreciated at all as I'm stumped.
