Thanks for providing that info!
There’s quite a lot of complexity here and I’ll say right off that I think you’d be disappointed if you were to use USB graphics adapters to accomplish this.
Again, keep in mind that as you add more USB graphics adapters, your available system resources are depleted. This is fairly static if the display content isn’t actively changing, but as the display updates, more system resources are used. If you’re watching a full-screen video, every pixel on the display is being updated 60 times per second, which is quite a lot of data to push over USB. Multiply that by 6 displays and you can see where performance might take quite a hit.
The primary concern I have is your usage. You noted that you’ll have a movie going on one display, a game going on another, and trading charts (I assume that are actively updating) on the remaining four. The first red flag is the game. DisplayLink displays do not support 3D games, these are for 2D rendering only, and you will absolutely have a bad time trying to run any game on a DisplayLink display. The second is the movie; if you’re actively watching a full-screen video and the other 5 displays are updating content, you may (or likely will) see slow framerates on the movie.
The setup you’ve already tried will not work. What you’ve done here is connected a display in this fashion:
- DisplayPort port from display to DisplayPort cable
- DisplayPort to Mini DisplayPort adapter
- Mini DisplayPort to USB-C adapter
- USB-C to USB 3.0 Type-A adapter
- USB 3.0 to USB hub
- USB hub to computer
The video signal dies at step 4 in that process. The USB-C standard can carry DisplayPort signals, but USB 3.0 cannot. In order to carry a video signal over USB 3.0, you must have a specific USB graphics adapter. This is very different from just carrying a standard video signal over a USB-C cable (native GPU path vs USB graphics hook).
The final straw is your location. It appears you’re ordering from Russia, and we don’t sell in your region. Even if I were to come up with a workable solution (which is unlikely given your requirements), I couldn’t get product to your location.
