I want to run display port and USB about 10m with one cable?

[Joe W]

Okay so where I live is very tight on space for the most part, I have my PC behind my TV in the living room in the corner. In the opposite corner of the room I have my desk with my monitor where I want to be able to do my coursework ect. My tv will be what I game on due to it being 4k, the distance is too far for any Bluetooth devices to work properly else I'd just run a display port around the room. Am I right I thinking I could use a thunderbolt card and run just the one thunderbolt cable to a dock on my desk which I could use to run display to one monitor but also have access to USB 3? I'll need to get a motherboard with more pcie slots but I've been meaning to upgrade it anyway because the case has so much space, I've also got a 3080 in there so how would I get the display out from thunderbolt?

Thanks

The maximum specified length for Thunderbolt over wire is 3m. It might be difficult to find a cable longer than that, and since that is outside the official spec, it might not work properly if you do.

 

Search for a PCIe card that has DisplayPort in and Thunderbolt out. Your typical TB add-in card does not transport a video signal. You need one you can plug your GPU into.

I'm watching the video of linus titled I may never upgrade again, where he inserts a Thunderbolt addin card - then plugs displayport to mini displayport in on the new card. I assume then you could run that Thunderbolt to a dock and output the display from the dock?

That card listed above will give you a USB Type C port with DisplayPort Alt Mode, however its not Thunderbolt. Those cards are talked about here: https://dancharblog.wordpress.com/2020/07/20/add-usb-c-with-dp-alt-mode-to-your-desktop-pc/

Before buying some add-in card think about just running 2 cables. 1 DisplayPort and 1 USB. Both have to be active or fiber cables for this length though. So either way, it's gonna be quite costly.
