Looking for a PCI card with USB-C output that supports DisplayPort Alt Mode. You need to connect your existing DVI monitor and add a second display, possibly using an unconventional setup. I'm here to help demonstrate that it's possible.

Ironically, that card is actually present... though it appears as a GPU with some RTX models featuring a USB-C port intended for VirtualLink. However, it supports full displayport over USB-C. Beyond that, your request isn't feasible. You're after an adapter from USB 3.0 to HDMI that includes a very low-power graphics chip, suitable for streaming services like YouTube, Netflix, or Discord on an external screen—though not for gaming. You could purchase an HDMI to DVI adapter for around $7 if needed.

Sure, I'll make that sound more natural.

I'm planning to share it on YouTube while playing on my main screen. Thanks for the tip—I'll check one of those out.

There is something available now. You'll need a SUNIX (UPD2018) USB 3.1 Dual Port USB-C PCI Express with alternate mode. It might be hard to find, but it's out there. Good luck!
