I'm relatively new to using PCs and have had mine for about six months now. It's a fully custom-built rig, and I recently added an extra monitor for playing racing and truck driving games. However, I've been struggling to duplicate the displays; no matter what I do, it just extends the monitors instead. I tried reaching out for help, and even Best Buy took control of my computer to troubleshoot but couldn't resolve the issue. They suggested a Geek Squad member might need to come look at it. I was hoping someone here might have experienced something similar and could offer some advice on what to do next.

Definitely try using Windows + P to switch between display modes. If you've done that and it still doesn't work, your graphics card software might be overriding the Windows settings. This can be a common problem. It's worth diving into that software to see what's going on.
First off, make sure both monitors are connected directly to your graphics card, not one to the GPU and the other to the motherboard. You can also try using the Windows+P shortcut, as it can sometimes yield different results than going through the Windows settings. If issues persist, consider reinstalling your graphics drivers and checking the graphics card software for multi-monitor settings.
I feel you—Windows 11 can be tricky! Just double-check that your graphics card drivers are up to date. Sometimes it helps to reinstall them. Also, make sure both monitors are set to the same resolution in the Nvidia control panel; that can create issues if they're not.
