I want to share a pair of Dell S2719DC 27" QHD (2560 x 1550 @ 59 Hz) resolution USB-C monitors between two 2018 MacBook Pros. The MacBooks dual-boot to run either MacOS 10.15 Catalina and Windows 10 (work & personal). Each MacBook can drive two monitors by USB-C as is.

I'd like a USB-C matrix switch with four USB-C inputs and two USB-C outputs, so I can plug each laptop's 2 USB-C ports into the switch, and decide which PC uses the monitors at any moment. I've done a lot of Googling and come up empty.

This effectively, but all using USB Type-C connectors:

Monitor    Monitor
   |          |
   +----++----+
        ||
      Switch
      ||  ||
 +----+|  |+----+
 |+----+  +----+|
 ||            ||
Work          Home
Laptop      Laptop

Does anyone know if such a product exists?

Thanks in advance,

Steve.

    Hi K7AAY, yes I can. I'm just fed up of physically swapping both cables depending upon what I'm doing. – Stevo Mar 18 at 17:44

    Hi, thanks for taking in interest in finding a solution. Both machines are 2018 MacBooks dual-booted to run macOS and Windows. The monitors are Dell 27" QHD resolution. Both machines are capable of running 2 QHD monitors. The main thing is I just don't want to keep unplugging 2x USB cables between machines when I switch from work code to personal code. – Stevo Mar 18 at 19:00

    Latest versions of macOS and Windows BTW (on both laptops). The monitors are Dell S2719DC. – Stevo Mar 18 at 19:29

    Hi, yep, the displays are side-by-side. The refresh rate is 59Hz. That switch looks like it may do the job, but wow, it's expensive! – Stevo Mar 19 at 12:44

1) A pair of Acroname Programmable Industrial USB Type-C 4-Port Switches controlled by a NUC, micro PC, or creaky old lappie could do the trick. Sure wish they had a manual switch, though, to make switching easy.

USB-C 3.2 for video is so new, and devices for all the different versions of USB-C are so inconsistently implemented because of all the things it can do, that we're just not seeing much stuff which ain't spendy.

==

Now, since the MacBookPro supports Thunderbolt 3 on the USB-C we have a less spendy solution.

2) StarTech.com has a Thunderbolt 3 device with one USB-C 3.2 in, two 3.2 USB-C out. The second StarTech out port could be converted to HDM(I). Since your monitors also accept HDM(I), adding such a conversion cable provides the second signal to each monitor. Then, an app which runs in Win10, an iOS phone/tablet or Android phone/tablet tells your monitors to toggle (pro version) between the USB-C 3.2 A/V data input to the monitor and the HDMI A/V data input to the monitor.

    They are MacBook Pros. I've edited the question to reflect this. – Stevo Mar 20 at 14:29
