Use USB-C to Displayport on desktop PC?
My regular video output port on my desktop PC is starting to glitch a bit and seems unreliable. The same monitor and cables work well with other computers, so I'm pretty sure they're not faulty.
My PC has a USB-C port, so I'm considering getting a USB-C -> Displayport adapter, or a USB-C dock, to connect the monitor via USB-C instead.
Would this be feasible / a good idea?

What make/model desktop PC, and what graphics card, etc.?
You might consider researching "solutions to upgrade your Desktop PC to have either a USB-C with DisplayPort alternate-mode OR a Thunderbolt 3 output":

I have a pretty decent graphics card (RTX 2070), and if I remote desktop into the PC I can see that it still works. I can still use it for e.g. CUDA, and Windows discovers it and reports no problems. It's just that the output ports, both the HDMI and DisplayPort, seem glitching, especially the HDMI. The DisplayPort seem to work some times.
That's why I thought I'd maybe use the USB-C port.
Otherwise it's an Intel i5 CPU with an ASUS motherboard and 16 GB ram.
Edit: I also have a USB-C port on the PC. Do I need to add anything else for a USB-C dock or adapter to work?
If your graphics card has a usbc port, it should work just fine for display out and usb signalling. Ive used a usbc hub on my 2070’s port and gotten display out without a problem. Just make sure you have Nvidias drivers for it, they should come with the normal graphics drivers.
The USB-C port is not on the graphics card, but it does use NVIDIA drivers, I think. At least I can see NVIDIA USB-C drivers installed.
Edit: Or maybe there is one on the graphics card too. I’ve got to check when I get home.
Edit2: It turns out I do have a USB-C port on the GPU. I just didn't find it before, below the plastic thing covering it.
Thanks :)
